AquaMetrix Dissolved Oxygen Sensor 4-20MA (%+ppm)

Product ships within 5-10 business days. All sales are final except for damaged shipments which must be reported within 12 hours of receipt. The AquaMetrix AM-ODO is the only optical dissolved oxygen sensor with a 4-20 mA output for percent saturation and concentration. It can connect to any PLC, recorder, DCS, or loop controller analog input, or the AquaMetrix AM-2300 web-enabled controller. Unlike electrochemical DO sensors, optical dissolved oxygen sensors are inherently self-referencing. They don't require a filling solution, a warm-up period, or sample flow. The sensor membrane lasts for up to two years, and is easy to replace. The corrosion-resistant body is designed to stand up to harsh environments in wastewater applications. Key applications include wastewater treatment, sewage, boilers, fish farms, and aquaculture. Dual measuring range 0-20 ppm (mg/l) and 0-200% saturation with 0.1 ppm resolution Automatic DO concentration compensation switch for salinity; Salinity input ran
