Solutions for iodine measurement include the CAL Check standards for verifying and, if needed, the calibration of our portable photometers. Each CAL Check standard is supplied with a Certificate of Analysis stating the accuracy and traceability of the standard.
Accessories include spare cuvettes and caps for photometers.
Checker HC are reagent based colorimeters in which there is a color change that occurs based on iodine concentration in the sample. The handheld colorimeters, like portable and benchtop instrumentation, use the Beer-Lambert principle to determine the color change and then display results on the LCD.
A portable photometer dedicated to the measurement of iodine is available. The portable photometer has a CAL Check feature that allows for performance verification and, if needed, recalibration using the CAL Check standards. The portable meter is available as a meter only or as a kit. The kit version includes a rugged carrying case and CAL Check standards.
Benchtop photometers include multiparameter versions for the laboratory and wastewater market. These meters include many other key water quality parameters. All benchtop have a digital pH electrode input allowing it to be used as a traditional pH meter.
Spectrophotometers are available that have iodine method pre-programmed into the meter. The spectrophotometer offers the highest precision due to the quality of the optical system that has a wavelength accuracy of +/- 1.5 nm. The spectrophotometer allows for custom methods to be developed.
