Name: Stationary Flammable Gas Detecting Probe
Brand: Midwest Group

Feature

	Adopting the advanced home and abroad sensor of low power consumption
	Having site gas content (0~99% LEL) display, the operators on site can acquaint with the site conditions timely
	With function of RS-485 transmission, able to connect with Bus Model Gas Monitor(SP-2003) or computer
	Having the automatic calibration of zero point to avoid the measurement error due to zero drift
	With numeral display and can be easy to identify in darkness
	Automatic fault alarm when the sensor is invalid or damaged
	Adjusted with magnetic rod to realize adjustment without opening the cover
	With prompt of wrong adjustment to avoid wrong adjustment and ensure proper operation
	Wide range of power supply (12~32 V DC) and with reversed polarity protection
	With on-off value output of alarm setting and fault on-off value output for controlling the ventilating equipment and fault alarm at site
