CD4 Multi-parameter Gas Detector

Product Details

CD4 multi-parameter gas detector meets ia protection level of intrinsically safe type, and is applicable to the detection of methane, carbon monoxide, oxygen and carbon dioxide gas parameters in coal mine hazard zone 0. Meanwhile, with high-range design, it can also satisfy the detection of high concentrations gas in the zone 0.

Main Performance

• Continuous detection of 4 high concentration gases and ultralimit alarming;
• Detector adopts high intelligent micro-controller as a control unit as well as high-precision sensors as detecting elements with high sensitivity and reliability;
• It adopts 128*64 LCD screen with a wide temperature range, display is clear and reliable;
• Infrared remote control calibration, do not need to open the sealed containers filled with toxic gases for calibration, more conducive to safety;
• With serial communication function;
• With sound and light alarm, it is suitable for underground noise environment;
• It adopts infrared gas sensor with high precision, good selectivity , high reliability, nontoxic, oxygen-independent, little environmental interference, long life and other advantages;
• It complies with explosion-proof requirements of Exial grade of national standards and is suitable for the most dangerous zone 0 that is a specified dangerous zone in GB50058-92, it does not ignite even in the worst case.
