Gas sensors

Gas sensors

Industrial and commercial environments often contain hazardous gases that are invisible, odourless, or only detectable at dangerous concentrations. AHOYSYS gas sensors provide continuous monitoring of PM2.5, PM10, CO2, oxygen (O2), ammonia (NH3), and ozone (O3) levels, triggering alerts before concentrations reach unsafe thresholds.

Our sensors are deployed in chemical plants, wastewater treatment facilities, cold storage units, food processing factories, and underground car parks where regulatory compliance and worker safety require continuous gas level monitoring and automatic ventilation control.

  • Monitors PM2.5, PM10, CO2, O2, NH3 (ammonia), and O3 (ozone)
  • Configurable alert thresholds with relay output for ventilation control
  • WiFi and Modbus RS485 connectivity
  • Suitable for industrial, food processing, and wastewater environments
  • Calibration certificates available on request
