about ph metwr

1.How to use calibration:Press CAL for 5 seconds to enter the calibration mode, press in turn to select the powders corresponding to 6.86, 4, and 9.18 to complete the calibration.
2.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.
3.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.
4.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.
5.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

Instructions for use of PH calibration powder:

Calibration powder: pH standard solid substance. It can be used after adding water. Suitable for the calibration of any type of ph meter. Each package can prepare 250ML standard solution.

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

tips

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.

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