Spectrophotometers are available that have the anionic surfactant 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 used as well.
A portable photometer is available to measure anionic surfactants. 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 includes a rugged carrying case and CAL Check standards.
In this category are the anionic and nonionic surfactant reagents for the photometers.
Solutions for surfactant 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.
