AirLink 6940 NXP Wireless Fixed Gas Detector
The RKI AirLink 6940 NXP series AC powered ambient air multi-gas detector simultaneously uses up to four sensor elements to detect an array of gases. The assembly reports once a minute with the reporting rate increasing to once every five seconds if the target gases exceed a preset background level.
The Airlink 6940 NXP Operates from an AC power supply with an internal backup battery pack. Magnetic switches allow for non-intrusive calibration while in the field as well as full system settings and diagnostics.
Features:
- Electrochemical, PID, or IR sensors available
- Wireless communication via 900 MHz radio and 52 networks or 2.4 GHz radio and 78 networks
- Dual battery powered w/ a 2-year maximum battery life for electrochemical sensors or a 1-year maximum for low-power infrared sensors
- 3 Push-button interface (ADD, MENU, SUB) with
corresponding magnetic, non-intrusive switches
- Explosion/flame-proof certification for select gases
- 1-Year warranty
- Optional remote-mount sensor kit with enclosure
Applications:
- Petrochemical plants
- Refineries
- Water & wastewater treatment plants
- Pulp & paper mills
- Manufacturing facilities
- Chemical plants
