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.

Detecting water parameters accurately such as ph levels are fast and easy with this water tester. Easily observe the living environment of aquatic organisms.

Ideal for home or laboratory uses. Digital TDS pH meter for water can be used to test drinking water, swimming pools, pH balance in aquarium, bath tub, spa, wine, beer and any other liquids, or anywhere needed to test pH value, PPM and get accurate data.

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.

Clean the electrode with distilled water Every time before and after use, gently wipe it with a clean, soft cloth when you're done before capping it again.

Be sure to add water according to the required ratio, otherwise it will affect the accuracy of the calibration and increase the error.

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.

When you find that the pH meter reading is inaccurate, you can contact us at any time, our team provides 24-hour after-sales service.
