The plug-n-play rack-mount DO90 Trace DO2 Analyzer from Electro Chemical Devices provides continuous precision measurement and alarming of trace dissolved oxygen levels in boiler feed water, supporting electric power generation steam turbine systems. It has a lead silver, galvanic, dissolved oxygen sensor with a durable PFA Teflon membrane. The sensor is combined with an intelligent universal transmitter designed for continuous service. The sensor is housed in a rugged, 316L flanged stainless steel body for use in rugged industrial process environments. It is a smart, digital device with a noise-free digital signal for easy communication. All data processing is internal to the sensor, and the calibration information is stored in the sensor’s memory. It provides integral temperature measurement, and has an easily replaceable electrode cartridge. It offers users a measurement range of 0.001 to 20.00 mg/L or ppm/ppb auto-ranging. 800/729-1333; www.ecdi.com.
