Accurate water quality measurement requires frequent calibration of the meter. These calibration solutions allows calibration against a NIST traceable standard reference solutions.
Supplied in handy packets containing approximately 20ml of solution each, simply tear off the top of the packet and dip your clean meter into the solution to calibrate the meter.
Cleaning your meter after every use and calibrating as frequently as accuracy requirements demand is recommended.
HM Digital solutions are made from established formulas and are standardized with meters calibrated with NIST standard calibration primary solutions. Careful handling and good cleaning (electrode cleaning solution) are essential for a good measurement result.
Box of 20 assorted calibration solutions containing 20ml of HM Digital calibration solution.
