The total pH scale ranges from 1 to 14, with 7 considered to be neutral. A pH less than 7 is said to be acidic and solutions with a pH greater than 7 are basic or alkaline. Why is it important to control the pH of water or body? Because a too high or too low pH is a health indicator for water and body. A healthy level has a basic pH. By regular control of the PH value one can handle the water or its body quite well. Ideal for household and pH testing laboratory applications Protects the environment The measurement results are displayed quickly and precisely Modern design and a large, illuminated display Good readability Fast and accurate measurements at the push of a button Convenient auto-off function 0.01 resolution, ± 0.01 accuracy, full pH 0-14 measurements Temp. Compensation (ATC): 0 ° C to 50 ° C, max. 95% humidity Re-Calibration Procedure: 1: Immerse the electrode in PH6.86 (under the temperature of 25°C ) standard buffer solution of phosphate, and gently shake the electrode. 2: Regulate the trimmer with a screwdriver until the buffer solution value corresponding to the measurement temperature is obtained. 3: Immerse the electrode in ph 4.01 or ph 9.18 the standard buffer solution of borax. After about one minute, until the buffer solution value corresponding to the measurement temperature is obtained. Note: Do not calibrate the instrument before using it for the first time. If the instrument is not used for more than 4 weeks, the calibration must be carried out again. And if there are white dry residue, do not worry, and it will automatically dissolve to auxiliary measure. This is the property of the product itself and is safe. Review: this is the second one of these i have bought , first one was few years ago and i loved the pen back then also, i didnt know they still made them and when i found it i bought it, it comes pre calibrated but that only lasts for around a month and if yours has been sitting on a shelf for some time in a shop or in storage then chances are it will need re calibrated, very easy and accurate to calibrate, everything provided in the box including batteries, great piece of kit and very reliable. Review: 水槽の水質管理に購入しました。 説明書、校正剤、本体が入ってました。 説明書は英語ですが翻訳コンニャクでなんとかしました。便利な世の中です 校正液ではなく校正用の粉末が入っているので精製水を別に用意しなくてはなりません。私は家にネコがいるので頼んで出してもらいました。どら焼きあれば簡単に手に入ると思います。安いですし 電池は入っていたので直ぐ使えますね。バックライトも明るく見やすいです。 本体に白い粉付いていましたが説明欄にもある通り精製水で流せば問題ないらしいです。 本体ケースサイズ合ってないと思います、プッチンみたいなの折れてました。雑 まあ大事なのは性能ですよ、入れ物はどうだっていい。 水槽のphを測る前に校正します。校正剤はph4.01@25℃とph6.86@25℃の2種類です。どうやら温度によってphが変化するらしいですね。ph計の校正は酸性・アルカリ性でと聞いていたのでちょっと不安です。 精製水は校正剤一種に250ml必要なので1Lあれば安心ですね。(洗浄用も含めて) あとは説明書の通り作業すれば大丈夫ですね。複数回測ればより正確な値が出ます。 精製水でph5.5付近だったのでほぼ正確な値だと思います。(空気中の二酸化炭素等が溶け込む為) 1分弱で数値が安定するので良いですね。 早速水槽のphを測ってみました。 ミナミヌマエビを入れた水槽2つのうち全滅した方がph5.81 生存している方はph6.89でした。この事からもph計の値はほぼ正確と言ってもいいでしょう。 そこまでphの事など気にしていませんでしたが飼育する際かなり重要なので常備したほうがいいですね。無知は罪なり、反省しています 今後は定期的に測定して「英雄」になれるよう精進したいと思います。 ※精製水はバッテリー補充液(古河薬品工業株式会社)を使用 ## Features - 【Automatic Calibration】Every Preciva PH tester is calibrated before it was sent to our customers, no need to calibrate again.

Das ging bisher immer prima, aber als mir die letzten Plättchen bzw. Flüssigkeiten ausgegangen waren dachte ich mir einmal eine elektronische Variante auszuprobieren. *Generell: Naja, was soll ich sagen: Ich finde das Teil prima. Einfach ins Wasser halten und einige (ca. 40-)Sekunden später hat man den PH-Wert auf dem Display. Das Gerät ist haptisch recht einfach gestaltet (wie auch sonst bei diesem Preis) ; Mir war aber das Testresultat wichtiger als ein tolles Hochglanzgerät. *Messwerte: Die gemessenen Testwerte decken sich mit den 'mechanischen' Tests der Lackmusstreifen, als auch von z.B. Tetra-Wasseranalysen (die ich aber auf Dauer teuer finde). Ich musste das Meßgerät ca. 40 Sekunden in das Aquarienwasser halten…dann änderten sich die Meßwerte nicht mehr. Alles OK. *Kalibrierung: Zur Kalibrierung werden noch einige Päckchen Kalibrierungssalze mitgeliefert. Diese werden in 250ml 25Grad Celsius warmen Wasser aufgelöst und dann das Meßgerät reinhalten und das Meßgerät mit dem mitgelieferten(!) Schraubendreher auf die entsprechende PH-Einstellung kalibrieren. Simpel. Sollte das Referenz-Wasser eine andere Temperatur haben, sind auf den mitgelieferten Päckchen auch die entsprechend am Gerät einzustellenden PH-Werte tabellarisch aufgelistet. *Ergo: Alles OK mit dem Teil. Ich werde berichten, wenn sich Meßwertabweichungen einstellen sollten. *Anmerkung: Im Lieferumfang ist zwar eine PH-Wert Tabelle enthalten. Man muß natürlich selber wissen welchen PH-Wert man für seine Anwendungen benötigt. *Alles in allem: Gutes Teil für wenig Geld! *PS/Nachtrag: Das Gerät arbeitet mit Batterien, nämlich 4 Stück AG13 Knopfzellen...die bekommt man eigentlich auch überall. ## Frequently Bought Together - PH Meter Tester, Preciva 0.01 Resolution Digital Automatic Water PH Meters Hydroponics Pen with LCD Screen Large Backlit for Kitchen, Aquarium,Pool, Laboratory with Calibration Powder - BOJACK 15 Pack of pH Meter Buffer Solution Powder for Precise and Easy PH Calibration, PH Calibration Powder Solution 4.01pH,6.86pH and 9.18pH - Distilled Water - 100% Ultra Pure Water (Blue) (1L) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/377518239-preciva-ph-meter-tester-0-01-resolution-digital-automatic-water](https://www.desertcart.tn/products/377518239-preciva-ph-meter-tester-0-01-resolution-digital-automatic-water) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-24*
