Note: Some customers have reported that the product data bounce, which is a normal phenomenon. (When using this product: After putting it in water, the data will slowly change from the last decimal point, because the acidity meter needs to adapt to the test environment, and the data will be stable after about 1 minute of rest, which is the data of the final test. In addition, if the water wobbles, the data will also bounce, so the test should ensure that the water is still.)

Please note:All items don't include batteries， the reason is that the package will be returned by the logistics provider if there are batteries in the package,please understand!




Correction with standard buffers:

1. Pour an appropriate amount of 6.86, 4.01, (temperature 25"C) standard buffer solution into separate clean beakers.

2. For accurate calibration, each buffer is divided into two beakers, one beaker is used to rinse the electrode, and the other is used to calibrate, so that the degree of contamination of the standard buffer solution can be minimized.

3. Tap ON/OFF to power on.

4. Put the instrument into the standard buffer, and gently shake, when the value is stable, press the CAL key, the instrument enters the automatic calibration state, the value is constantly flashing, until the flashing stops and the value of the calibrator is consistent, complete the correction.




Correction with purified water (PH 7) :

1, in order to accurately calibrate, use two beakers, one beaker is used to rinse the electrode, the other is used to calibrate, in order to reduce contamination.

2. Tap ON/OFF to power on.

3, calibration, need to put the instrument in pure water, press the CAL key, display 6.86 in the flashing, the instrument enters the automatic calibration state, the value will flash, until the flashing stops, the display value is 6.86, complete calibration.

Note: Calibration water temperature is recommended at 25 degrees Celsius

The calibration liquid should use distilled water or pure water (PH 7), not tap water, tap water quality is complex and PH is unstable.

Accuracy of calibration cannot be guaranteed./ae01.alicdn.com/kf/H3d000cb4c60f4211a8d88b59054c7285C.jpg>
