Turbidimeter Model 850
Easy Installation
Initial installation of our insertion sensor is as easy as installing a 1-inch female NPT fitting in the process piping. The submersible sensor can be suspended by its cable. Once installed, both turbidity sensors can be inserted and removed without interrupting process flow.
Wide Dynamic Range
Our turbidity meter has four ranges from 0-2 NTU to 0-2000 NTU. The low-level range (0-2 NTU) has a resolution of 0.001 NTU and is useful in processes where very low turbidity measurement is required. The higher ranges can be used on raw water supplies and other processes where turbidity is monitored before filtering.
Data Communication
Our turbidimeter comes standard with an isolated 4-20mA output, and other outputs are available.
Minimal Maintenance
The Model 850 uses a light source with a 13-year life expectancy which provides long-term stability and very low maintenance. Although our turbidity monitor is easily calibrated by the end user, calibration drift is minimal. Because sensor removal is simple, the optics can readily be cleaned as necessary.
Warranty
Limited one-year warranty against defects in material and workmanship.
