3-IN-1 PH METER : Water quality tester has a 3-1 function, which can measure pH, TDS and temperature with Fe high precision. All-round measurement of water quality to ensure healthy water quality.
𝗪𝗜𝗗𝗘 𝗔𝗣𝗣𝗟𝗜𝗖𝗔𝗧𝗜𝗢𝗡
pH/TDS/Temperature plays a pivotal role in making the nutrients in your solution soluble so that they can be accessed by your plants. To help your plants thrive, pH meter gets the fundamentals right by measuring pH/TDS/temperature to ensure that these are always within the optimal range. Easily observe the living environment of aquatic organisms.

1. Before calibration, add the pH4.00/pH6.86/pH9.18 buffer powder into beaker with 250ml (under the temperature of 25℃) of distilled water, then stir until the powder has completely dissolved.
2. Press the ON/OFF button to turn on.
3. Press the TEMP / CAL button, adjust to pH mode.
4. Place the electrode in the pH 4.00/ 6.86/ 9.18 standard solution.
5. Wait for the readings to stabilize(usually 5~10 Seconds).
6. Press and hold the TEMP/CAL button for 6 seconds, then you can see corresponding value flashing 3 times which means calibration of pH is completed.
𝗡𝗼𝘁𝗲:
Do not turn on the switch of the pH meter in the air, which will interfere with the calibration of the pH meter. When the ph attribute value of the pH meter calibration solution appears, the number will always display an error of 0. In this case, the solution is: use our attached pH buffer powder to recalibrate the pH pen. After the calibration is completed, be sure to remember not to turn on the switch of the pH tester again in the air.
When measuring the same amount of solution, the pH value of the solution will produce errors with time and place changes. This change is normal, and it is not a wrong reading of the water test meter.
