Lab grade pH 4.01 Calibration Fluid 250ml

PH Calibration Fluid 4.01

Standard pH calibration solutions are good for use in virtually any application and with most meters. We recommend all electronic pH instruments should be calibrated monthly. Compatible with all pH meters and probes. 

Almost all pH monitors and controllers will require two points of reference to accurately monitor the pH that the probe is reading. You will want to use calibration solutions that are on either spectrum of the pH you intend to monitor.
