Water Quality Tester, Towallmark TDS Meter, EC Meter & Temperature Meter 3 in 1, 0-9990ppm, Ideal Water Test Meter for Drinking Water, Aquariums

WIDE USE: Ideal for Household or Laboratory Use, Suitable for Testing Ph Balance of Drinking Water, Pool, Aquarium, Ro System, Spa, or Hydroponics; Appropriate for Wide Range of Applications.

LIGHTWEIGHT & EASY TO USE e: Just remove the protective cap and immerse the PH meter electrode in the solution and press the button to be measured

AUTO CALIBRATION: The Ph Meter Has an Auto Temperature Compensation Feature That Adjusts to Water Temperatures and Water Quality to Give Ph Readings Almost Instantly. As Well, You Can Calibrate the Tester with One Touch Button Using Buffer Powder.

AUTOMATIC TEMPERATURE COMPENSATION: No more need to take care about the temperature of testing liquid, as ph meter has built in (ATC) automatic temperature compensation, so that it can accurately determine pH value of the sample at any temperature in a range of 0°C - 80°C (32°F - 176°F).

WAYS TO CALIBRATE:

Step 1: One packet of calibrate powder can be mixed with 250ml of pure water . Or you could pour 50ml of pure water with one-fifth of the powder to save the use of powder (the remaining powder can be stored in a cool and dry place, and it is recommended to use it up within one month);

Step 2: After adjusting the calibration fluid, turn on the PH pen and put the probe into the calibration fluid. If the value does not match the calibration fluid’s 6.86, press and hold CAL for three seconds. The screen flashes the value and displays 6.86. Wait for five seconds and displays END. Calibration completed

If the calibration 4.01, 9.18 method is the same.

Solution for wrong calibration result :

Assuming that the calibration result is wrong, the pen recognizes ph 9.18 or ph 4.01 after calibrating ph 6.86 .

Step 1: Take 50ml of purified water or distilled water, and then import one-fifth pack of 6.86 calibration powder, stir evenly, put the PH pen probe in water for One Hours.

Step 2: Then turn on the phe, press and hold the CAL button for five seconds, then let go, the value flashes, and the END calibration is completed.

Except the ways above, you could long press the switch and calibration keys at the same time for five seconds, restore the factory settings, and then test.

( The test difference might within 2% with reset control , and the powder calibration's test difference is within 0.1%-1% )

Note: If it is difficult to control one-fifth of the powder in a pack, you can pour about one-quarter or one-third. The powder can be more but not less. The maximum amount of water in a pack is 250ml.

Q&A

1.Q: How often should I calibrate my ph meter pen ?

A: One calibration can last for about half a month. When testing polluted water quality, more frequent calibration is required to ensure the accuracy of the test value

2.Q: Can I use it to test the supernatant water after the soil has settled ?

A: Yes , but the premise is that there is no corrosive water, or it will damage the accuracy of the glass probe and reduce the lifetime of the glass probe.

3.Q: Can I use this to test Urine ？

A: Yes , it can. But the premise is that the liquid is not corrosive.

4.Q: Can I test two kinds of water without calibrating ?

A : Yes , but when testing the liquid that is not pure water or distilled water, after the test, you need to put it in pure water or distilled water, wash it and wipe it dry, and then test the next liquid (to ensure the accuracy of the value of the next test liquid)

5.Q: Why my ph meter switch and digital display are not sensitive ?

A: It might be caused by low battery. Just replace the battery and it will work again .
