WebFor best results, select a standard value close to the sample value you are measuring. Alternatively use a calibration solution value that is approximately 2⁄ 3 the full scale value of the measurement range you plan to use. For example, in the 0 to 1999 µS conductivity range, use a 1413 µS solution for calibration. WebFisherbrand Traceable Conductivity, Resistivity, and TDS Meters are ideal for measuring reagent-grade water to meet CAP, ASTM, NCCLS, and ACS specifications as well as for measuring conductivity in chromatography, biology, food, electronics, and water analysis. All readings automatically referenced to the international standard of 25°C.
