Product Description

■ 4~20mA.DC(Transmitter), RS-485 Modbus, HART Communication
■ FND LOCAL DIGITAL DISPLAY
■ MODEL : QM-9000D(T), QM-9000D(O2)

FEATURES

◉ QM-9000D(T) is the highest quality gas detector used to measure toxic gases and oxygen in real time in a place with potential toxic gases.
◉ Flickering and lighting functions are optional for users.
◉ QM-9000D(T) has the self-illuminating FND(LED) to identify concentrations of atmospheric toxic gases and oxygen even in a dark place.
◉ High-intensity LED Flash Lamp(H.HH).
◉ 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 detector itself outputs 4~20mA.DC. QM-9000D(T) product provides 24V.DC output with the function of Dry contact(1st, 2nd) output(Option).
◉ The computer systems and controller function as a two-way transceiver for communication.
◉ Enclosure explosion-proof structure(IP66).
◉ The Galvanic isolated RS-485 Network is excellent at detecting noises, so it can locally limit the spread of damage caused by thunder-strokes. It is the most powerful Field-Bus Network.
◉ When the detector is added, it is connected to the nearest communication line and relevant computer
monitoring systems for automatic extension and reduction. Thus, it is excellent at reducing installation
costs and enhancing maintenance management.
