Description

The RKI Air Alert series ambient air toxic gas detector is a versatile assembly that uses an electrochemical, infrared or PID sensor element to detect a variety of gases. Wire powered (12 to 35 VDC) with 4-20 mA analog and RS-485 Modbus outputs. Magnetic switches allow for non-intrusive calibration while in the field as well as full system settings and diagnostics.

The Air Alert represents the latest leading edge technology in fixed gas detection today.

Application

  • Petrochemical plants
  • Refineries
  • Water & wastewater treatment plants
  • Pulp & paper mills
  • Manufacturing facilities
  • Chemical plants
