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