PH Meter for Water Hydroponics Digital PH Tester Pen 001

Product Description


PH tester usage related issues:

When the PH meter is turned on in the air, the value jumps irregularly, which is a normal phenomenon. The value in the air cannot be used as a reference.

When measuring the water with the PH meter, it needs to be stirred gently (to remove the bubbles attached to the probe), and it takes a period of stabilization. It is normal for the value to jump up or down during the test. Please do not just insert it and read it immediately.

White crystalline salt appears around the electrode of the PH meter, which is a normal phenomenon of the PH electrode, and the electrode can be removed by immersing it in water and cleaning.

The PH meter electrode is made of glass, which is fragile. Please do not drop it or touch it with your hands. Do not test the water above 50℃. Do not test the strong acid and alkali, which will cause the electrode glass to burst.

ph meterph meter Precautions:

Please note that the PH pen probe is a glass product and is a fragile product. Please do not collide with things. Once the damage is not replaceable, you must protect the probe. After use, use absorbent paper to gently absorb the water on the probe.

Instructions for use of PH calibration powder:

Calibration powder:pH standard solid substance. It can be used after adding water. Suitable for calibrating any type of ph meter. Each package needs to prepare 250ML of purified water.

(Note that the configured water must be purified water or distilled water. Tap water and mineral water cannot be used to configure the calibration solution.

The water must be added in the required proportion, otherwise it will affect the accuracy of the calibration and increase the error)

The configured calibrators shall be sealed with clean bottles and stored in a cool place away from light. The shelf life of the calibration powder is 2 years, and the shelf life of the calibration solution after configuration is 6 months

Matters needing attention:

PH meter has been calibrated before delivery, the buyer does not need to re-calibrate after receiving the goods!

In the following cases, the PH meter must be re-calibrated:

Has been used for a long time after calibration;Special electrode use Frequently;The measurement accuracy requirements are relatively high.

【Mini Size】The mini size ph meter we designed allows you to easily put it in your pocket, so you can take measurements anytime, anywhere. It can help you test it whether you take it to the pool, on a trip, to the beach or camping.
【Family Essentials】As a tool to improve the quality of life. Can be used to test drinking water, swimming pools, PH balance in aquarium, RO system, spa or hydroponics. Basically all the environments that need to test PH value can use this tester to get accurate data.
【Easy to use】turn on the switch,put the probe into the water and stir (make the small glass ball fully contact the liquid) and the value can be read when the value is stable.
【Automatic temperature compensation】There is no need to care about the temperature of the liquid being measured. The PH meter has an automatic temperature compensation function, which can be adjusted according to the water temperature and water quality.
