The Pyxis SP-380P is a simple to use handheld fluorometer offering direct measurement of fluorescent polymers used in cooling and process water applications. The device has a built-in sample cell allowing samples to be directly filled in, eliminating the need for purchasing and using sample cuvettes. The SP-380P is a dual channel fluorometer which measures both PTSA (0-300ppb) and fluorescent polymer (0-20ppm). 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.
