Ion selective electrodes measure specific ions directly, and they need standards at known concentrations to do it accurately. Thermal Scientific carries ISE calibration standards from Ricca Chemical and LabChem, including fluoride standards with TISAB at low-ppm levels, along with other ion standards for water and process testing. Calibrating with fresh standards that bracket your samples keeps results dependable.
Pair your standards with the right hardware: browse our electrodes, pH meters, and multi-parameter meters, and see our environmental calibration standards for related water quality work.
It is a solution with a known concentration of a specific ion, such as fluoride, used to calibrate an ion selective electrode before you measure samples.
TISAB (total ionic strength adjustment buffer) holds ionic strength and pH steady so fluoride electrode readings stay consistent. Our fluoride standards are available with TISAB.
