Bluelab pH 7.0 buffer 500 ml, calibration solution

Bluelab pH 7.0 500 ml, calibration solution for pH meters.

To improve the accuracy and lifespan of the Bluelab pH meter, you must get into the habit of regular cleaning and calibration. Calibration is an easy process to perform and is the same for all Bluelab pH meters and pens.

After cleaning the pH probe, you must calibrate it using pH calibration solutions at two reference standards - 4.0 and 7.0 pH. After calibration, you can immediately start measuring pH values ​​again. You must recalibrate each time you clean the pH probe and when the meter alerts you that calibration is required.
