ISE Standards

Hach Ion Selective Electrode (ISE) standard solutions are designed for use in proper calibration of the Ion Selective Electrode. The provided solutions are available in 500 mL or 1 L bottle sizes, as ready-to-use solutions at 1, 10, 100 and 1000 mg/L standard ISE measurement values in multiples of 10, or for preparing different concentration combinations when a narrower analytical range is desired. All Hach ISE standard solutions are traceable to NIST for optimal electrode calibration records. For all Hach ISE standard solutions, a special Certificate of Analysis is available that can be downloaded from www.hach.com: Support/Service, Certificate of Analysis menu using the product part number and batch number.
Additionally, a complete set of ISA (Ionic Strength Adjuster) reagents is also available for all parameters measured by ISE. Available in different package sizes as powder packets or solutions.
