AG-GDT-310 Toxic Gas Detectors
Fixed Ammonia Detector
Electrochemical NH₃ detection for refrigeration plant rooms and cold stores
4–20 mA Modbus RTU
Features
- Ammonia refrigeration machinery rooms require fixed detection under most national codes
- Low alarm for occupational exposure; high alarm for emergency ventilation and plant shutdown
- Ammonia is lighter than air and rises — pair a high-level head with one at the machinery
- Reports directly to BMS or PLC alongside the refrigeration controls
