Chloride ISE 100 ppm Standard

HI4007-02 is a 100 ppm (mg/L) standard solution of chloride used to calibrate the chloride solid state ion selective electrode (ISE). Hanna ISE standard solutions are manufactured with high purity chemicals and bottled in our own state-of-the-art facility.

ISEs require calibration for accurate readings when performing measurement techniques such as direct measurement and incremental methods. Calibration of up to two points is recommended for enhanced accuracy. Volumetric glassware can be used to make dilutions of standard solutions to bracket the expected concentration of the sample to be measured. ISE calibration standards and sample solutions should always have the same ionic strength; the exact volume of ionic strength adjuster (ISA) must be added to all standards and samples prior to measurement.
