Calibration Technologies (CTI), GG-NH3-100-ST, SAFECELL Electrochemical Gas Sensor, Ammonia (NH3), 0-100 ppm, Stainless Steel Enclosure
Features:
- Designed “food industry tough” for Engine Rooms, Freezers, Docks, Blast Cells, Food-Processing areas, Refrigeration Systems, Breweries, Refineries, and more.
- The GG-NH3 uses both electrochemical and catalytic bead ammonia specific sensor technology, designed to adapt to harsh industrial environments.
- Ammonia Electrochemical Sensor Elements are equipped with SAFECELL technology which checks the electrical viability of the electrochemical cell every 40 seconds. If it is determined that the cell is failed or missing; the 4-20 mA output will drop to 0.5 mA and fault.
- Circuit board sealed in potting material to protect sensitive sensor components and copper tracing from corrosion.
- Environmentally adaptive, NEMA 3RX heated Enclosures safe for outdoors and washdown areas.
- GG-NH3 Transmitters are targets gas, range, and sensor technology specific.
- Built in 3 stage heater for freezing temperatures.
- SGS listed to UL 61010-1, and CSA C22.2 No. 61010-1-12
