Bluelab pH 4 Solution, 250 ml 

Ensures That pH Meters Provide Accurate Readings

• Dependable and reliable calibration
• Essential for use with all Bluelab products
• Standard calibration solution
• Closely monitored for accuracy

Bluelab pH 4 Solution, 20 ml ensures that pH meters are giving accurate readings. Bluelab pH solutions are made for Bluelab products but pH calibration solutions are universal and can be used with other pH tester brands. Bluelab solutions are manufactured specifically for Bluelab products and are referenced to high laboratory standards to ensure your Bluelab products last longer and maintain accuracy.

The pH measuring equipment must be cleaned and calibrated regularly to ensure they are giving the user accurate readings. pH instruments are calibrated to pH7.0 first (buffer) then to pH4.0 (slope).Many of Bluelab's conductivity equipment does not need calibrating as they are factory calibrated here at Bluelab.
