The immersion fittings are designed for either pH or ORP (Redox) measurements in tanks, open vessels and drains. They have a "hoisting cable" for easy maintenance. The program includes fittings for mounting of 1 electrode, 3 electrodes, 4 electrodes or alternatively 3 electrodes and a cleaning system. As standard, the immersion length can be between 0.5 and 2 m. A flange for fixing in tanks, etc. is available on request.
