Polarographic dissolved oxygen sensor 332P

process

Cell for the measure of dissolved oxygen, PVC or PVDF body, 12 mm diameter and 120 mm length, designed for laboratory and industrial application (it can be installed into Mod.SI16x sensor fitting and so directly inserted into closed tanks or pipelines). The measuring cell is polarographic, with 2 electrodes (Pt and Ag) immersed into an electrolyte solution and separated form the process fluid by a PTFE membrane permeable to Oxygen. A temperature sensor allows measure thermocompensation and temperature indication. Measuring range : 0-20 ppm O2; minimum sample flowrate under the membrane required for a correct measure is 0,5 cm/sec. This cell may also be used to measure oxygen in air.
