pH 4.0 Calibration Solution

R220
INFORMATION

Description

Bluelab calibration solutions are essential for use with all Bluelab products. Bluelab Solutions are manufactured specifically for Bluelab products and are referenced to high laboratory standards to ensure your pH measurement tools last longer and maintain accuracy.

Electrodes need to be calibrated on a regular basis because as an electrode ages, its glass changes resistance. This resistance change alters the electrode potential, and therefore, accuracy of the reading. 

Calibration Solution should be stored in a cool place out of direct sun and heat.
