The CSIM11 measures pH for the range of 0 to 14 pH with an accuracy of ±0.1 pH unit. 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.
