Product Description

IR(Infrared) Gas Detector
■ 4~20mA.DC(Transmitter), RS-485 Modbus, HART Communication
■ FND LOCAL DIGITAL DISPLAY
■ MODEL : QM-9000D(IR)

FEATURES

◉ QM-9000D(IR) can continuously detect flammable gases, CO2, and CO.
◉ Providing a solution to measuring the optimal gas.
◉ QM-9000D(IR) is the highest quality gas detector used to measure target gases in real time in a place with potential toxic and flammable gases.
◉ Cutting-edge technology based on infrared ray measurement principle.
◉ Ensuring more than five-year stable lifetime.
◉ No malfunction due to the application of dedicated sensors.
◉ QM-9000D(IR) has the self-illuminating FND(LED) to identify atmospheric flammable concentrations even in a dark place.
◉ QM-9000D(IR) has a self-warning light at preset gas concentrations(6. LED, Event).
◉ Without opening its cover, its magnetic key and computer-based monitoring systems can adjust the zero point, control concentrations, correct temperatures, check the records of the latest calibration dates, and so on.
◉ The computer systems and controller function as a two-way transceiver for communication.
◉ Enclosure explosion-proof structure(IP66).
