Water Quality Sensors


The CSIM11-ORP is a versatile sensor that measures oxidation reduction potential (ORP).
The sensor is designed for submersion or insertion into tanks, pipelines, and open channels. The CSIM11-ORP is similiar to the CSIM11, but includes a 0.2 inch platinum band wrapped around the glass electrode. This allows the CSIM11-ORP to respond to the electron density in the fluid. A titanium ground rod runs inside the PPS outer body to eliminate ground loop errors. An internal amplifier boosts the signal, decreasing signal interference.
