CSIM11 pH probe

The CSIM11 is a versatile sensors that measures the full pH range.
The sensor is designed for submersion or insertion into tanks, pipelines, and open channels. The sensor features a plunger-style pH glass electrode allowing it to be mounted at any angle. The porous Teflon® liquid junction is less susceptible to clogging as compared to conventional reference junctions. A titanium ground rod runs inside the PPS outer body to eliminate ground loop errors. An internal amplifier boosts the signal, decreasing signal interference.
