New Products

	Statox 505 The stationary gas detection system compliant with SIL 2 srandard
	Statox The fixed gas detection system with automatic self test.
	Statox 501 The fixed gas detection system for toxic and combustible gases. The Statox 501 Controller operates with 4 – 20 mA transmitters as well as with catalytic sensors.
	Statox 501 IR The fixed gas detection system for combustible gases uses the infrared absorption method of gas detection. It features on site display and non intrusive one- man calibration. The reliability of this system is unmatched. The measuring range varies from ppm to % LEL.
	Statox 501 IR LC The low - cost version fixed gas detection system for combustible gases uses the infrared absorption method of gas detection in. The Statox 501 IR LC sensor heads are backward compatible to systems using catalytic sensors. They can be used to upgrade such systems without replacing existing hardware.
