Feature(may vary by option.)
●【10 in 1 Function】: Digital water tester for measuring PH, TDS, SALT, SG, ORP, EC, Hydrogen, Resistivity, Temperature and Nutrient.
●【Smart Design】: Equipped with rust resistant probe and clear LCD display with backlight, easy to read and record. Small size and light weight, easy to carry and store. The automatic shutdown function automatically turns off the power after 5 minutes without any operation to save power. It adopts a backlit high-definition Large display screen to display 4-digit values and the corresponding physical quantity units.
●【High Sensitive】: Built-in high-sensitivity probe, detachable and easy to install. The sensitive probe enables the Ph meter to measure values in seconds.The PH tester can set the max or mini limit of PH/EC/ORP. If the test result is out of range, the value of the PH tester will be displayed in red.
●【High Precision】: The high-sensitivity probe provides you with a complete measurement range, multi-function switching at will, with data retention function and low-battery indication function. When the measured value is stable, just press the HOLD/TEMP button to lock the measured value and take it out for viewing, which is really simple.
●【Application】: Widely used in drinking water, swimming pool, fish tank, aquarium. The digital ph meter can also be used to measure RO System, spa, soap mixtures, food, wine, beer or any other liquids.

Description
Calibration Made Easy
How to calibrate a pH meter?
1. Before calibration, prepare 4 beakers with 250ml of clean water/pH 4.00/pH 6.86/pH 9.18 standard solution.
2. Rinse the probe electrode with clean distilled water pH0 and wipe dry. Turn on the pH meter and adjust to pH mode.
3. Immerse the electrode in pH 6.86 buffer solution and when the value stabilizes, press the "CAL" key for 5 seconds, the screen will display "CAL" and when pH 6.86 blinks 3 times, the calibration of pH 6.86 is complete.
4. Repeat above steps to calibrate pH4.00 or pH9.18
