Solutions for phosphate 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 the replacement cuvettes and caps for the photometers and Checker HC.
Chemical Test Kits
Phosphate Chemical Test Kits (CTK) are available for basic water quality testing. There are two options for a phosphate CTK. One is for basic color cube with 5 points of resolution while the other option is for the Checker Disc that has 50.
Multiparameter CTKs are available for boiler and cooling tower water treatment. Both kits include other key parameters.
For educational use there are the Hanna Backpack Labs. Both of the Water Quality and Marine Science Backpack Labs that include a phosphate test kit along with a teacher’s guide that discusses the importance of the parameter.
Checker HC, like a chemical test kit, are a reagent based design 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. The change in color is not subjective as with using the naked eye. A marine version is available with chemistry that is compatible for use with saltwater aquariums.
Portable photometers are available in two ranges. The portables are able to display phosphate results in multiple chemical forms. The portable photometers have a CAL Check feature that allows for performance verification, and if needed, recalibration using the CAL Check standards. The meters are available as a meter only option or as a kit. The kit version include a rugged carrying case and CAL Check standards
Benchtop photometers include multiparameter versions for water treatment, wastewater treatment, environmental, and aquaculture. Each photometer is customized with the parameters used by a specific industry. The benchtop photometers are able to display phosphate results in multiple chemical forms. All benchtop have a digital pH electrode input allowing it to be used as a traditional pH meter.
Spectrophotometers are available that have phosphate methods in several ranges 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 used as well.
Replacement reagents for the photometers, Checker HC, and chemical test kits. Reagents for the photometers are available in 100 or 300 test quantities.
