By utilising the “Smart Cell” Detector Array Technology, developed by Rivertrace, 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. 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 for Hazardous area Environments classified as Zone 1 & 2.
The Smart Cell Bilge Alarm is readily available as a 5ppm version if required. It can also be tailor made for Hazardous Environments (Zone 1 & 2) as an Exd system with Auto Clean, all enclosed in an explosion proof cabinet.
APPLICATIONS
- Sewage Treatment Plant Effluent Monitor.
- Brewing Quality Monitor.
- Groundwater Effluent.
OPTIONS
All options can be ordered from new or retrofitted to existing Rivertrace Smart Cell monitors.
AUTOCLEAN
The autoclean option has been designed to ensure that the measuring cell glass tube is kept free from fouling. Cell fouling is recognised as a leading cause of monitor malfunction. Fitting the Autoclean removes the need for the ship’s crew to remember to clean the cell manually.

CALIBRATION CHECK
The monitor’s calibration can be checked using our calibration check kit. This is an approved method of demonstrating that the unit is still working correctly.
