Description

Comboinstruments pH 4.01 and 6.86 Calibration powder is a powder for calibrating electronic pH meters.

It does not create any color on the liquid and does not contaminate the electrode.

After mixing, the liquid lasts about 1 month.

Here you get two calibration powders, one with a buffer of pH 4.01 and one of 6.86.

These have a tolerance range of ± 0.01 pH.

Store in a cool place without sunlight.

On the back of the bag there is a table for correcting the buffer rate depending on the temperature.

Each pH meter should be calibrated regularly to maintain its accuracy.

Instructions for use:

1. Pour the contents into 250ml of demineralized water at a temperature of 25°C.

2. Stir with a plastic spoon and wait until the powder is completely dissolved.

3. Then calibrate the meter according to the instructions.

4. The pH meter should be calibrated with both pH 4.01 and 6.86.

5. Calibration should be started with acidic solutions and finished with alkaline ones.
