1.2 Pyxis Major Features
The SP-800 is a multi-wavelength colorimeter. It provides colorimetric measurements at 7 LED
wavelengths and nephelometric turbidity measurement using white LED and infrared LED as the
excitation sources. The SP-800 is pre-calibrated for colorimetric measurements of analyses common
in industrial water treatment and other water testing in the laboratory or in the field, such as chlorine,
phosphate, iron, and copper. Main features include:
⚫ The SP-800 is pre-calibrated for measuring turbidity in the range of 0 to 200 NTU.
⚫ Automatically select the primary wavelength according to the method selected and switches to the
secondary wavelength to extend the primary measurement range.

⚫ Display 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.
⚫ The user can update the calibration parameter of any pre-calibrated colorimetric method by testing
a standard solution first and then following a setup procedure to update the calibration parameters.
⚫ Built-in Bluetooth allows easy connection to PC or mobile apps for downloading datalog and adding
new colorimetric methods.
⚫ Pyxis specific methods such as non-cyanide containing zinc reagent are available.
⚫ More wavelengths including near UV 365 nm are available than other colorimeters.
