GasMark M1 Ammonia Gas Detector
The GASMARK™ M1 industrial gas detector for ammonia retains the proven reliability, rugged design, and 4–20 mA output of the GG‑NH3 detector, while adding built‑in Modbus communication and optional relays for facilities that want greater connectivity, diagnostics, system flexibility, and cost savings.
The blue Smart Sensor Module protects the sensor cell with a 3 stage heater and provides easy access for field replacement. The optional onboard display gives an at‑a‑glance indication of the current ammonia concentration at the detector.
