ISEs require calibration for accurate readings. 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.
ISE Standards
Our wide selection of HANNA ISE Standards are made and bottled in our own state-of-the-art solutions facility. ISE Standards are required for direct and incremental measurement techniques and are available with certificate of analysis.
