Bacharach’s all new state-of-the-art GDX-350 low temperature transmitters with B-Smart®technology provide accurate detection of ammonia (NH3) and carbon dioxide (CO2). These full featured standalone transmitters are designed to operate in extreme temperature conditions found in blast chillers and deep freezers. GDX-350’s unique design includes programmable heaters for both the sensor and electronics that are automatically activated when temperatures drop below user selectable temperatures. Placing the sensors inside these harsh operating environments allow for quick detection and response to the mallest leaks, protecting human life as well as product and machinery. Features – Non-Dispersive Infrared (NDIR) CO2 detection Range of 0-5% – Electrochemical sensors for detecting 0-500 ppm of Ammonia – Heated sensors and electronics for low temperature operation (-55 degrees Celsius) – Graphic LCD for real time monitoring of concentrations – 4-20 mA and optional Modbus® RTU interface – 30 minute onboard data trend – B-Smart ®sensor program – Optional Relay outputs
