Digital Redox ORP testing meter

-1999mv to +1999mv pen type digital redox water tester ORP meter

Step 1: Put the orp meter into a saturated potassium chloride solution for 2 to 3 hours.

Step 2: Clean the electrode with water, then put orp meter into 256mv standard solution and shake gently.

Step 3: Adjust correction potentiometer with a mini-screwdriver until the reading is 256mv.

How to Use:

Step 1: Remove the protective cap, clean the electrode with water.

Step 2: Press " on-off" key, then put ORP meter into the water, the water should not exceed the waterline.

Step 3: Wait for around 10 minutes until the reading becomes stable, then press "HOLD" key to lock the measured value.

Step 4: After use, clean the electrode with water and wipe off water on the electrode.

How to calibrate the ORP meter?

The importance of ORP meter

Cautions:

1. While testing, gently stir the orp meter to remove the water bubbles on the electrode until the reading pulsate very slowly and reading become stable.

Normally it takes a few minutes or even approximate 10 minutes to stablize the reading.

2. Although the orp meter is waterproof, it should not be immersed in water for a long time, so the water should not exceed the water level in order to extend its life.

3. It is normal for the measured values of orp meter vary irregularly.
