HI-4012-21 0.1 M SULPHATE STANDARD
HI-4012-21
HI-4012-21 is a 0.1M standard Sulphate solution used to calibrate the sulphate solid state Ion Selective Electrode (ISE). Hanna ISE standard solutions are manufactured with high purity chemicals.
ISEs require calibration for accurate readings when performing measurements. Calibration of up to two points is recommended for enhanced accuracy. 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.
