FST-03 – designed for methane (CH4) and carbon monoxide (CO) concentration measurement in the air of the office and non-categorical industrial buildings (boiler-houses, garages etc.)

Resume
Specification	up to 8 CH4 or CO sensing elements /detectors/ connection unit data-transmitter unit -up to 8 CH4 or CO measuring sensors data-transmitter units -allows to connect up to 8 CH4or CO measuring sensor units (in any combination)
Indication range (on-scale range):
CH4volume fraction,	0… 5.00 %
CO mass concentration	10… 125 mg/m3
Advantages:	Each sensor unit is connected with a twin-core cable to a power supply and alarm unit with a twin-core cable that transmits data and supplies sensor units. Sensor units are interchangeable and no setting is needed when fixed (located) Communication length is up to 1000 m.
Performance capabilities:
	Audible and light warning (signaling) when gas concentration is more (exceeds) than two set (fixed limit) thresholds (in\for each link\channel)
	Switching of the external electric circuits (with 220V voltage) for the auxiliaries (separate (independent) actuating devices connection) (air fan, siren and etc.). (Switched current peak – up to 3 A). Peak current - up to 3 A.
Appendix:	The gas – analyzer supports data exchange with a PC and or industrial (on-stream) controller with (in) the RS-232 (joint\connector )interface as well as networking with the RS-485 (connector) interface (with external adapter).
