Smart pH ORP Controller Aquarium pH Monitor Wi-Fi for pH/ORP/Temp Measurements in Water w/Calibration, 3 in 1 Nutrient System Dual-Plug Fit with CO2 Bottle & O3 Generator for Hydroponics Plants

All I needed was a low cost meter, I have high quality probes and didn't need the control function plug-in portion. So I cut that off, added a 110 plug to the meter, and I have a great bench meter for my lab at a fraction of the cost of lab grade meters. So can't comment on probe function or pump control function. I was very pleased with the ability to calibrate using either the included reference standards, or the more common industry 4.01, 7, 10 solutions.

The fact that this meter has a temperature probe, but does not do automatic temperature compensation is one of those Chinese mysteries that will be relegated to the ages. Without ATC, it's not suitable for use in an ice bath -- or anywhere, really.

For the most part it works, however, there is a learning curve for the alarms. You basically set your high alarm setting, which turns on the doser at that set value, then immediately shuts off once it reaches the set value. The low alarm setting can be left to zero, unless you are battling low ph. There is no indication that the pump is on in the app, which would be a nice plus. App Grammer is also something they should take a closer look at. For example, "weeks" is lower case "Days" is capitalized "month" is lowercase and "Hour" is capitalized. They are not consistent and appears to be a rushed configuration. The time is also incorrect in the app, and does not sync with my actual timezone and the temp scale switch reverts back to Celsius each time you exit the app. Most of the words are squished together, like (currenttemperaturevalue), which would make more sense if they just displayed current temp. You not specifically need the Tuya app, as it works in smartlife if you already have that installed. You are also able to use this with the Kamoer KCP-X single doser.

Comenzó trabajando bien de después de un par de meses se quemó el fusible y cambie el fusible pero ya no enciende es una perdiera de dinero
