Solutions 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 a COD digestion reactor for use with the total iron reagents that require digestion. Also available are spare cuvettes and caps for photometers.
Chemical Test Kits
Iron chemical test kits are available in a variety of ranges and include a basic color cube with five points of resolution and the Checker disc version that has a continuous scale for increased resolution.
Checker HC are reagent based colorimeters which measures the color change that occurs based on iron 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.
Portable photometers dedicated to the measurement of iron are available in two ranges along with multiparameter versions that also measure other key water quality parameters. 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, wastewater, water conditioning and water treatment markets. These meters include many other key water quality parameters. All benchtop photometers have a digital pH electrode input allowing it to be used as a traditional pH meter.
Spectrophotometers are available that have iron 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 to be developed.
The following are the reagents used with the photometers, Checker HC and chemical test kits. The total iron by digestion method can be use on the wastewater benchtop photometer or spectrophotometer.
