Hach Ion Selective Electrode (ISE) standard solutions are for use to accurately calibrate Ion Selective Electrode. Available as 500 mL or 1 L bottle size in ready to use solutions covering standard ISE measuring decades: 1, 10, 100 or 1000 mg/L; or for use to prepare other concentration combinations when a narrower analytical range is desired. All Hach ISE standard solutions are NIST traceable for optimum electrode calibration records.
A complete set of ISA (Ionic Strengh Adjustor) reagents are also available accordingly for each parameter measured by ISE. Available in different packaging sizes as powder pillows or solutions.
