Description
High-precision digital pH meter pen for testing the acidity and alkalinity of liquids and water (pH Tester). This device is the professional and essential tool for monitoring water balance and determining its pH level. It is ideal for checking the efficiency of household filter cartridges (such as alkaline cartridges for increasing water alkalinity) and is widely used for testing drinking water, fish tanks, swimming pools, and hydroponics.
The device features a clear digital LCD screen that provides direct readings, with a simple operating system containing only two buttons: ON/OFF and CAL for calibration and adjustment. Its compact and lightweight design allows you to carry it and test water quality and safety anytime, quickly and easily.
Correct Usage:
-
Remove the black protective cap from the bottom.
-
Press the ON/OFF button.
-
Immerse the lower electrode (glass) of the device into the liquid to be tested (avoid submerging the entire device or exceeding the maximum immersion limit).
-
Gently stir the device in the cup and wait for about 30 seconds until the digital reading stabilizes on the screen.
-
After use, clean the electrode by rinsing it with clean or distilled water, gently dry it with a soft tissue, then replace the protective cap.
