Product Description
For accurate pH measurement frequent calibration of the pH meter is advised. This pH calibration solution allows calibration against a NIST traceable standard pH4 reference solutions.
Supplied in a handy packet containing approximately 20ml of solution, simply tear off the top of the packet and dip your clean pH meter into the solution to calibrate the meter.
Cleaning your pH 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 a pH meter calibrated with NIST standard calibration primary solutions. Careful handling and good cleaning (electrode cleaning solution) are essential for a good measurement result.
