Industrial Electrodes - Dissolved Oxygen Sensors

	MF 41
Application	This membrane covered amperometric oxygen sensor combines rugged design, identical dimensions to pH electrodes, integrated temperature sensor for automatic temperature compensation, high long-term stability and extremely low maintenance. Short response time, rugged multi-layer membrane, low flow sensitivity and short polarisation time make this sensor ideal for pilot and laboratory plants, water technology, pools and fish farms.
Specification	-5 ... 45 °C 0 ... 20 mg O₂/l max. 1 bar PSU shaft Ø 12 mm immersion length 120 mm built-in Pt 1000 max. cable length 20 m MF 41 K /PG: fixed cable 5 m and hex nut PG 13.5 MF 41 SMEK: PG 13.5 threaded SMEK plug head, connection cable K 39
