Product Overview

This conductivity verification standard from Giorgio Bormac is formulated as a potassium chloride aqueous solution with a nominal conductivity of 147 µS/cm at 25°C (133 µS/cm at 20°C). Supplied in a 500 ml ergonomic autocal bottle with an integrated calibration compartment, it is designed for the routine verification and quality control of conductivity measurement systems in laboratory and industrial settings. Traceability to NIST is provided through Giorgio Bormac's internal laboratory certificate, which accompanies each unit.
