Apera Instruments, LLC-AI314 Premium Series EC60 Waterproof Conductivity Pocket Tester Kit, ±1% F.S Accuracy, Easy Switch of EC/TDS/Salinity, Replaceable Probe

It does cost a pretty good price when compared to those cheap Sub $20 TDS meter. I got an old cheap TDS meter I got from Home Depot but the old cell battery was dead and expanded. Didn't known the battery cell was bad and forced into the meter and breaks the cap and battery slot. I hate those watch battery type cells that is not as reliable as AAA size batteries. I had to get a new and better TDS meter that is more accurate and will last a long time. This Apera EC60 Tester Kit Meter can handle 4 types EC, TDS, Salinity, and of course temperature. I wanted the Apera TDS Meter but they were out of stock. For a few tens this one does 2 additional types. I have ran a few tests. Distilled Water Great Value brand = 1.00 ppm TDS R.O. System = 20 ppm TDS R.O. boiled water = 26.9 ppm TDS (Not sure why slightly higher? Maybe the container we used?) Refrigerator Water Filter = 294 ppm TDS Tap Water = 306 ppm TDS ( I think my refrigerator water filter needs to be changed or it is not working to well. Overall, I am very happy with this purchase I made. The EC60 was pre-calibrated with a tested calibrated quality certification and I was able to get a 1.0 ppm TDS on my distilled water. Other features I found out from the quick laminated guide was you can do 7 programs. Changes like option to turn off/on P1 auto lock, P2 leave 1 min default/off/on, P3 - P3 Change temp coefficient and TDS factor for calibration, P5 change salinity type measurements, P6 change temperature from F° to C°, and lastly P6 does restore back to factory default (factory resetting). This might be a little overkill for some but for me who appreciates accuracy in 1% and a high well made meter, the calibration kit, and sturdy carrying case is a perfect whole kit for testing my home water.

I use this to measure TDS in my water, as I have a filter system for it. It was already accurately calibrated when I received it. It's well packaged, and very easy to use and read. As a HS science teacher of many years, I've had a lot of cheap crappy instrumentation devices and this one is VERY nice and well made. It comes in a very nicely molded case that will stand up to some abuse. Very good value for a well made device. Don't go on the cheap when measuring anything like this. the 1% margin is much better than higher error margins, especially for TDS filter systems. Also, stick color reading are crap. For a hot tub or pool that is probably ok, but not for anything else, like a water filter system, or for water quality studies. This would be a great addition to an environmental science dept at any school or college .

I’ve been running cheap EC pens for a while and didn’t realize how off they were until I got this. The EC60 is legit—readings lock in fast and don’t bounce around, which makes mixing nutes way easier and way more consistent. I mixed a batch and hit 1.97 EC exactly, rechecked it 10 minutes later and it was still dead on. That alone sold me. The screen is super clear, and I like that it shows when the reading is stable so you’re not second guessing. Build feels solid too, not like those flimsy $15 pens. Waterproof is a plus because I’ve already splashed it a couple times…. Overall, if you’re serious about dialing in your feed, this is 100% worth it. I should’ve bought it sooner.

My less expensive meter was a lot quicker to stabilize. It seems like this EC meter takes a veryyyy long time to acclimate to the temperature of the solution.. which for me is normally +10-20F over ambient. This causes a longggg delay while I watch the reading (even with the smiley face showing) continually drift down towards, almost 300-400 microsiemens in total, as the temp indicated slowly comes up to accurate. The delay is so long that I have to press the power button every time the 1min *Maximum* backlight timeout occurs. I end up pressing the power button 3-4 times in order to see the reading as it starts to stabilize and become accurate. Why doesn't apera allow me to set the backlight to more than 1 minute??? If this time wasting daily annoyance wasn't enough in itself to get a bad review, the box only contains two out of the three needed calibration solutions to make sure that this meter is accurate down to reverse osmosis (low EC) levels. There is even a third spot in the box that is filled with a foam piece. As it stands, my tap water and my RO water both read the same at 90 to 100 when I know both are 30 and below (RO is something like 5-7 microsimens on my system). This is because I can only calibrate to the medium and high EC levels unless I go buy my own calibration solution. So while I liked apera PH60 Meter a lot, I really wish I didn't buy this EC Meter. It costs 7x what the cheaper one did and has cost me 3x the amount of time on every use. Buy something else

I have the Apera PH-20 PH meter and have been very impressed by it. I have tried cheap meters that just don't get the job done, so when looking for a Cond/TDS/ Sal. tester I gravitated to the Apera EC60. A little late for me since they have a unit that does PH as well as all the other parameters I was looking for,but since I had the PH meter already, the EC60 was the choice. Just got it today and put it to work. Once you have one of their other units it is fairly simple to learn. I performed a PPM testing on my spring veggie plants from seed, and it went like clockwork. You will pay more for their units, but you will get a unit that works well and should last a long time.

Device is accurate and fast. Calibration is easy once you get a hang of all the buttons and the symbols displayed on the screen. User guide is confusing as it mixes up both EC and PH meters. One example is on the cap it says "do not store probe in distilled water" but user manual says let the probe store in distilled water.

Absolutely excellent product! Easy to calibrate and stays that way. All my meters are apera!

I received the EC60 last week and I have used it once. The case is nice, but it's a bit large for a simple water meter, so a bit more difficult to store. The directions are very clear and easy to read and understand, but I think it should have clearly stated the device was pre-calibrated and ready to use. The calibration process is a bit much and I am not sure when to detect when the meter needs to be re-calibrated. It also does not indicate how to store the meter - dried tip - cap on with liquid, no liquid? Overall the meter has a nice case, easy instructions, easy to use, clearly visible readings but the overall use manual and troubleshooting tips were not available.

Na samym początku od zakupu urządzenie działało prawidłowo. Po pewnym masie musiałem je kalibrować, gdyż odczyty na buforach dawały duże rozbieżności. Niestety urządzenie nie wykrywało prawidłowych buforów i pokazywało tylko wartość dolną zakresu L czyli 84 mikro Siemensy / cm. Próba przywrócenia ustawień fabrycznych funkcją P7 - nie dawała żadnego rezultatu. Po pewnym czasie nie dało się również urządzenia wykrywać za pomocą bluetooth na telefonie. Uważam że jest to zbyt droga zabawka jak na swoją cenę - nie polecam.

very worst product. cannot possible to calibrate the instrument by given solution Don't buy it

Prodotto completamente Fallato. Fin dalle prime misurazioni funzionava a tratti. Dopo 2 settimane si accende ma i sensori misurano sempre 0. Non è il primo prodotto Apera quindi so come funzionano. La mia fregatura è che l'ho comprato ma l'ho usato qualche mese dopo quindi nessun reso. Mi sono fidato. Uno scherzetto da 140 euro. Direi che con Apera ho chiuso soprattutto calcolando le decine di alternative

... muss nicht unbedingt BlueLab sein ... Zur 1. April 2024 Situation habe ich mir zusätzlich das EC60 zugelegt, um den Nährstoffgehalt des Gießwassers zu überprüfen/anzupassen und um meine DWC richtig in den einzelnen Wachstumsphasen mit Nährstoffen zu versorgen. Das PH60 habe ich bereits seit fast 1.5 Jahren im Einsatz (Aquarium) und bin sehr zufrieden. Mit dem EC60 zusammen habe ich nun das Rundumsorglosmesspaket. - beleuchtet (John R.: Es leuchtet blau! ;D) - wasserdicht (Batteriefach mit Gummidichtung, Rest gekapselt, habe ich aber auch nie wirklich komplett unter Wasser gehalten, wozu auch) - mit 3x AAA betrieben (Knopfzellen ade, nachhaltig) - austauschbarer Sonde (nachhaltig) - langfristig genaue Ergebnisse Bei beiden Geräten sind Kalibrierlösungen dabei. Das PH60 habe ich seit dem Kauf nicht wieder kalibiriert und es zeigt weiterhin exakt die Werte der beigelegten Lösungen an. In die Schutzkappen habe ich KCL-Lösung gefüllt (gerade soviel, das die Sonde feucht gehalten wird), um die Glassonden sauber zu halten. Bei dem PH60 war ein Minifläschchen dabei, was sich schnell aufbraucht, ganz ohne beim EC60. 250ml KCL irgendwo günstig mitbestellen, der Viertelliter hält ewig. So haltet ihr eure Glassonden frisch und braucht nicht ständig kalibrieren: - aus der KCL gefüllten Kappe -> Spülen der Sonde mit Wasser (KCL Lösung entfernen) - Messung / Messungen - nach Gebrauch Spülen mit dest. Wasser - und wieder zurück in die KCL Lösung / Kappe (Bild 2) (tauscht die KCL erst, wenn die Flüssigkeit in der Kappe verbraucht ist, braucht ihr nicht nach jedem Messen tauschen, ggf. nur nachfüllen!) Die Geräte haben einen Clip, wie beim Kugelschreiber und eine kleine Öse, also klemmen und hängen möglich, es schwimmt auch an der Oberfläche, wie die BL-Geräte. Alles in allem sehr viel günstiger als von BL und ebenso gut. Letzter Hinweis: Bei manchen Growtabellen wird der EC-Wert (von 0-3) in Millisiemens pro Zentimeter (mS/cm) angegeben. Hier wird der EC-Wert in Mikrosiemens pro Zentimeter (µS/cm) angezeigt, sprich von 0-3000. Wer es hier auf die Spitze treiben und genauer als mit 0.1 (eben mit 0.001) arbeiten möchte, ist hier sehr gut bedient.

The Apera Instruments EC60 Premium EC/TDS/Salinity Pocket Tester is handheld and portable kit that enables the user to test the following Electrical Conductivity measurements to an incredibly accurate degree: 1. Conductivity 2. TDS (total dissolved solids) 3. Salinity 4. Temperature The first thing you really should do if you’re thinking of picking one of these up is take a look at the product page on the Apera Instruments website. On there you’ll find videos and much more information about the product than detailed on the Amazon listing. The kit comes with everything you need to effectively test the electrical conductivity of your soil, hydroponics setup or pool. Included in the set you have two calibration solutions (4.00 and 7.00). You use the 7.00 calibration solution first, to ensure the pocket tester is calibrated to 7.00, then bring it down to 4.00 with the second calibration solution. The whole calibration process is quick and simple to do and will ensure your pocket tester returns the most accurate readings. The setup of the kit is designed to be as user-friendly as possible, giving you everything you need in a handy unbranded protective storage case. From using the pocket tester for a few weeks now I’m incredibly happy with its performance and the results. It’s so incredibly quick and easy to use and the results are incredibly accurate. I really can’t recommend the pocket meter enough for your hydroponic setup.
