Description
Air Alert Datasheet [PDF]
Air Alert Operator’s [PDF]
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. 4-20 mA analog and RS-485 Modbus outputs available. 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.
