Maximum accuracy is high on the agenda here at Hanna. Browse our Conductivity Calibration Solutions specifically produced for Conductivity meters and electrodes. Hanna conductivity electrodes can be calibrated in just a few minutes, wherever you are working, thanks to our range of conductivity solutions in different forms and values. Sachets, for instance, could be very useful out in the field as well as the laboratory. Each label shows the product batch number, expiry date, and a conductivity/temperature correlation table. EC value is calculated at 25°C.
