SMART TURBIDITY MONITOR - The monitor accurately analyses the quality of the sample stream and outputs the turbidity value in nephelometer turbidity units (NTU

By utilising the “Smart Cell” Detector Array Technology, developed by Rivertrace technologies, the monitor accurately analyses the quality of the sample stream and outputs the turbidity value in nephelometer turbidity units (NTU) Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye.

A manual cell cleaning device is included as standard to easily enable routine maintenance and prevent Optical cell fouling which is recognised as a leading cause of monitor malfunction or incorrect reading. By simple operation of the manual cleaning device, the measuring cell remains in optimum operating condition. 

Replacement calibrated measuring cells can be purchased for easy change over and calibration verification kits enable the user to demonstrate the monitor is within factory calibration.

The Smart Turbidity Monitor is also available in for Hazardous area Environments classified as Zone 1 & 2.
