Used to calibrate the fluoride solid state ion selective electrode (ISE). ISE standard solutions are manufactured with high purity chemicals and bottled in Hanna's own state-of-the-art facility. ISEs need to be calibrated for accurate readings when performing measurement techniques such as direct measurement and incremental methods. For enhanced accuracy calibration of up to two points is recommended. 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. Volumetric glassware can be used to make dilutions of standard solutions to bracket the expected concentration of the sample to be measured.
