   High Range Turbidity System Specifications

 

Connect this Raw Water Turbidity sensor
to a PLC for seamless integration with
industrial control systems. Use any computer
to display data, calibrate and customize the measurement without an intermediate
analyzer electronics box. A LD500 local display can be used if desired. Sensor has a second measurement mode to report sediment load. It does this using a spectral measurement to compensate for particle color, size and shape.

• 0 to 4000 NTU measurement range

• Conforms to ISO 7027

• 90 degree and 180 degree light paths

• Rugged, foul resistant construction

• Local and Remote configuration and
   diagnostics

• Temperature measurement included

• Direct data reporting

• Plug & play industrial communications
   adapters
