Accessories include cuvette cleaning solution, microfiber cloths, and replacement cuvettes and caps for photometers.
Checker HC, like chemical test kits, are reagent based with a color change based on concentration. The handheld colorimeters, like portable and benchtop instrumentation, use the Beer-Lambert principle to determine the color change.
Single parameter photometers are available to measure manganese. Multiparameter portables are available that measure calcium and manganese hardness. The portable photometers have a CAL Check feature that allows for performance verification and, if needed, recalibration using the CAL Check standards. The portable meters are 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 water quality, wastewater and water conditioning. Each photometer is customized to have the parameters used by a specific industry. All benchtop have a digital pH electrode input allowing it to be used as a traditional pH meter.
Spectrophotometers are available that have manganese methods 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.
Reagents include the reagents used with Checker HC and photometers.
