Product Description

■ TRANSMITTER TYPE(4~20mA.DC)
■ MODEL : QM-4700D(T), QM-4700D(O2)

FEATURES

◉ Applying a sensor used for the toxic and oxygen.
◉ QM-4700D(T) features excellent selectivity and minimizes the effects of interfering gases by means of the prin-
ciple of detecting specific gases and reaction to target gases.
◉ Enclosure explosion-proof certificate(by KOSHA).
◉ Calibration and program settings(Zero), and a span with the automatic setting buttons, except for 4~20mA.
◉ Calibration and maintenance by one person.
◉ Minimizes effects of temperature/humidity and electric noises.
◉ Connect analogue standard output(4~20mA) signals to DCS & PLC monitoring systems.
◉ QM-4700D(T) can measure toxic gases and oxygen in industrial sites in real time, show remarkable performance in detecting toxic gases and oxygen that violate ermissible concentrations for the human body, provide 4~20mA. DC standard output, and be connected to every controller and monitoring system.
