DM-700 toxic replacement cell
$0.00
Teledyne Detcon DM-700 toxic replacement cell is a field-replaceable electrochemical smart sensor for detecting toxic gases and oxygen deficiency in industrial safety applications.
Detcon Model DM-700 toxic gas and O2 deficiency sensors are non-intrusive smart sensors designed to detect and monitor a wide range of toxic gases and oxygen deficiency in air. Features include electrochemical cell technology with detection ranges from 0-1ppm to 0-10,000ppm for toxic gases and 0-100ppm to 0-25% by volume for O2 deficiency. The sensor includes a four-character alphanumeric LED display, microprocessor-supervised electronics in explosion-proof casting (ITM), automatic calibration via magnetic programming tool, standard 4-20mA analog output, and Modbus RS-485 serial output. Modular mechanical design with field-replaceable intelligent plug-in sensor. Operates from -20°C to +50°C. Factory calibrated with 2-year warranty and up to 2.5-year expected service life.
