The Pyxis SP-350P and SP-380P Fluorometers are simple to use handheld fluorometers offering direct measurement of fluorescent polymers used in cooling and process water applications. These devices have a built-in sample cell allowing samples to be directly filled in, eliminating the need for purchasing and using sample cuvettes. The SP-350P is a single channel fluorometer which measures fluorescent polymer only (0 to 20ppm) while the SP380P is a dual channel fluorometer which measures both PTSA (0 to 300ppb) and fluorescent polymer (0 to 20ppm). This patent pending technology combines cutting edge optical measurement of both fluorescent tracers commonly used in cooling and process water applications in one easy to use platform while compensating for color and turbidity interference commonly present in real-world waters.

Excitation wavelengths are 410nm for SP-350P and 365nm/410nm for SP-380P, with emission wavelengths 470nm (SP-350P) and 410nm/450nm (SP-380P). Wavelength accuracy is ±1nm. Both models feature a 320x240 TFT-LCD display and Pyxis LOCK-IN technology.
