The Pyxis SP-300 Series fluorometers measure the concentration of a fluorescent substance in a liquid sample. These fluorometers have a built-in sample cell and samples can be directly filled into the sample cell eliminating the need for purchasing/using sample cuvettes.

The Pyxis SP-350 is a uniquely designed handheld multimeter that measures PTSA. It is a cuvette-less device. Less than 5 mL water sample is needed to fill the sample cell for proper measurement. The Pyxis SP-380 is a uniquely designed handheld multimeter that measures both PTSA and Fluorescein, simultaneously. It is a cuvette-less device. Less than 5 mL water sample is needed to fill the sample cell for proper measurement.

The Pyxis SP-395 is an ultraviolet fluorometer. The SP-395 utilizes UV light absorbance to detect Halogenated TolyTriazole (HST) content in water. The results are instantaneous and, with proper application understanding, are highly reliable. The Pyxis SP-395T is an ultraviolet fluorometer that measures TolyTriazole (TTA) in a water samples. This device utilized UV light absorbance to detect TTA content in water.

All models feature TFT-LCD display, 9V alkaline battery operation, 40-106°F temperature range, 85% humidity tolerance, waterproof and drop-proof design. Measurement cycle adjustable from 15 to 999 minutes.
