(Fluorometer, colorimeter, and turbidimeter)

The SP -910 is a 3-in-1 fluorometer/colorimeter/turbidimeter device. It is a simple, robust, and intelligent device that mainly finds applications in the water treatment industry.
Manufactured by: Pyxis Lab Inc., USA

      Key Features 
  • PTSA and fluorescein
  • Measures PTSA and fluorescein in the same meter for your traced programs in cooling and boiler applications
  • Calibrate ST-500 directly
  • Calibrate a nearby ST-500 via built-in Bluetooth after measuring sample concentration. No laptop or other tool is needed
  • User-defined programs supported with non-linear calibration curves. Choose from over 60 programs, including reagent-less nitrite and chlorine dioxide measurement
  • Battery life doubled- six months or more, even with higher resolution LCD which is readable in direct sunlight
  • Turbidity range is extended to 0-100 NTU and 0-1000 NTU with auto-ranging
  • 16mm tube adapter is available for programs that require digestion
  • Talks to your smartphone for firmware upgrades and data log transfer

  • Environmental: IP67, dustproof and waterproof
  • The SP-910 is pre-calibrated for measuring fluorescein in the range of 0ppb to 600ppb and turbidity in the range of 0NTU to 200NTU
  • Automatically selects 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
