Product description

Color:15 pack - Only pH 6.86

The pH buffer solution powder is used to calibrate the accuracy of the electronic pH meter. The electronic ph meter has high accuracy, but after continuous use, it will become inaccurate. Therefore, the pH meter should be calibrated regularly.

The ph meter may need to be recalibrated mainly in these cases:
-Inactivity for long period, for example over 3-4 weeks.
-Very frequently used.
-Can't get a stable meter reading.
-After testing strong acid/alkaline.
-High test accuracy requirements.

Directions for use:
Step 1:Completely empty the powder into a dry glass container.
Step 2:Add 250mL deionized water (or distilled water) to the beaker.
Step 3:Stir until the powder has completely dissolved.
Step 4:Put the pH meter in the solution and gently stir and wait a few seconds for the result.
CAUTION: Not a drinkable solution!

Specifications:
Accuracy: ±0.01pH at 77°F(25°C)
✔ 15 pack ph calibration powder, all pH 6.86.
