Pyxis SP-800

(Multi-parameter portable colorimeter)

The SP-800 is specifically designed for municipal, environmental, and industrial water analysis. It uses common colorimetric reagents and provides colorimetric measurements at 7 LED wavelengths. It is pre-calibrated for colorimetric measurements of analyses common in industrial water treatment and other water testing applications in the laboratory or field environments, such as chlorine, phosphate, iron, copper, and many others. The SP-800 has proven to be statistically more accurate than other devices on the market.
Manufactured by: Pyxis Lab Inc., USA

      Key Features 
  • Pre-calibrated for measuring turbidity in the range of 0 to 200 NTU
  • Automatically selects the primary wavelength according to the method selected and switches to the secondary wavelength to extend the primary measurement range
  • Displays a concentration-time profile curve during the last time period in a colorimetric measurement. The user can terminate the timing process and take a reading if the displayed concentration reaches a plateau before completing the predefined time period
  • Pyxis specific methods such as non-cyanide containing zinc reagent are available
  • Wavelengths near UV 365 nm are also available
