The SP-200 OXI-Pocket is a unique all in one pocket colorimeter specifically designed for measurement of all primary oxidizing biocides and disinfectants commonly used in the municipal, domestic and industrial markets. The SP- 200 offers colorimetric testing of oxidizing biocides and disinfectants using both Pyxis Lab and conventional reagents available on the market and replaces the need for independent analyte pocket colorimeters or expensive multi-component colorimeters. The SP-200 also contains an integrated fluorometer enabling Pyxis Lab’s ‘DIRECT-READ’ methods for both Chlorine Dioxide and Bleach concentration in both low and high concentration ranges. This unique Pyxis Lab development allows users to test direct source samples of both Chlorine Dioxide and Bleach concentrate chemical solutions and determine precise concentration without the need for any reagents. This device is Bluetooth 5.0 enabled for data log transfer, firmware updates and screen customization via the uPyxis Mobile and Desktop App’s.
