1. Introduction
The Pyxis ST-735 inline turbidity sensor can be inserted to the compression fitting port of Pyxis custom-
made ST-001 Tee
assembly. The companion tee has two ¾ inch female NPT ports and can be installed to
an existing ¾ inch sample water line. The ST-735 can be also submersed into a vessel with using the
Pyxis MA-102S submersion adapter.
The ST-735 measures light scattering for the 0 – 100 NTU range using a white LED as the incident light
source, the 100 – 1000 NTU range using a 950 nm LED light source, and the 950 nm absorbance for the
1000 – 10,000 NTU range. The ST-735 turbidity sensor automatically selects the measurement method
needed for the sample according to the sample turbidity range detected when inserted inline.
The ST-735 probe can be easily removed from the system without the need of any tools for being
cleaned. The Pyxis ST-735 probe has a short fluidic channel and is be easily cleaned. The fluidic and
optical arrangement of the ST-735 probe are designed to overcome shortcomings associated with other
turbidity meters.
The 4-20mA current output of the ST-735 probe is internally isolated. It can be connected to any
controller that accepts an isolated or non-isolated 4-20mA input.
The Pyxis ST-735 probe uses long life LEDs as light source and will not require replacement in expected
life unlike conventional turbidity probes. This greatly enhances the robustness of the ST-735 probe. It
can be operated under a wide range of ambient conditions without the need for humidity and
temperature regulation. The performance of the ST-735 probe can be stable and consistent for a very
long period time.
