ORP standard buffer solutionPurpose: Used to calibrate the accuracy of electronic ORP testers. The electronic ORP tester has high accuracy, but with prolonged use, the detection results may deviate. Therefore, the tester should be calibrated regularly during use.

Product parameters

Correction frequency

1. The ORP tester should be calibrated every two weeks to ensure accuracy, as it is constantly in a powered on state (i.e. monitoring ORP values for a long time).

2. The ORP tester is used to periodically test ORP values and should be calibrated before testing to ensure accuracy.

3. After replacing the electrode of the ORP tester, the new electrode should be calibrated.
