The new generation of the Honeywell Analytics commercial gas monitor SQN8x series combines long proven sensing capabilities with state-of-the-art pumping technology to yield a highly reliable sample draw gas detection system.
The SQN8x offers accurate monitoring of the presence of a wide variety of refrigerants or other toxic and explosive gases in a surveillance area of up to 8 different zones. A low maintenance diaphragm pump draws ambient air to the sensor from a maximum distance of 1000 feet. A high performance sequencer synchronizes the mechanics and the electronics so that the levels of detectable gases are properly registered for each of the 8 zones. The unit is fully operational from the box, making for simple, hassle-free installation. The new generation of Honeywell Analytics commercial gas monitor SQN8x provides an excellent, cost-effective, centralized gas detection solution.
