Pyxis - Model SP-910 -Fluorometer/Colorimeter/Turbidimeter

• PTSA and fluorescein

  Measure 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

  User-defined programs are supported with non-linear calibration curves. Choose from over 60 programs, including reagent-less nitrite and chlorine dioxide measurement.

• Battery Life Doubled

  Battery life is six months or more, even with higher resolution LCD readable in direct sunlight.

• More Upgrades

  Turbidity range is extended to 0-100 and 0-1000 NTU with auto-ranging. 16mm tube adapter is available for programs that require digestion. The SP-910 talks to your smart phone for firmware upgrades and data log transfer.
