GAS DETECTION CONTROLLER- QM-7000SI SUNGHWA

Product Description

■ MODEL : QM-7000SI

FEATURES

◉ Single circuit monitor.
◉ Monitor with diverse functions.
◉ Providing 110/220V.AC, 50/60Hz, this is for domestic and overseas usage regardless of voltage frequency.
◉ QM-7000SI is a gas detection controller with artificial intelligence, which detects gas leakage and failures by decoding arithmetic operation without microprocessors.
◉ 4~20mA. DC output, an alarm, relay contact output.
◉ Automatic settings for a zero point, a span, and calibration can be processed on the front without volume.
◉ Connected to the local gas detector, QM-7000SI is to measure atmospheric gas concentrations in real time, to display the concentration, and to warn against concentrations as danger. Also, it is connected to external devices, PLC and DCS, to continuously measure gas concentrations.
