      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.
