Dor Yang CD4 Multi Parameters Gas Detector Product introduction: Dor Yang CD4 Multi Parameters Gas Detector is developed by our company is a kind of determination apparatus detecting a variety of gas concentration simultaneously and continuously.It adopts the most advanced sensor to keep the stability, anti-interference, free maintenance and long service life and other advantages, but also to avoid the detector's shortcoming of traditional principle detectors,such as parts exposed in the air are easily caused the fault or error alarm by the dust and other covering material parts. When the concentration of detecting gas in the environment reaches or exceeds a preset value,the detector alarms,and immediately sends out sound, light and vibration alarm, to remind us to take safety measures. This product is suitable for real-time detection of carbon monoxide, oxygen, hydrogen sulfide, methane and other gases in the coal mine underground pipes or other places.The staff make corresponding countermeasures according to the concentration displayed , in order to ensure the life safety of the staff. Technical indicators:
Types of gas | range | Low alarm setting range | High alarm setting range | Low alarm point |
CH4 | 0~4.00% | 0.5%CH4~4.00%CH4 | | 1.00%CH4 |
H2S | 0~100ppm | 1ppm~30ppm adjustable | | 10ppm |
CO | 0~1000ppm | 5ppm~500ppm adjustable | | 24ppm |
O2 | 0.0~30%vol | 5%vol~20%vol adjustable | 22%vol~24%vol | 19.5%vol |
High alarm point | TWA Alarm | STEL Alarm | Measuring range | Response time |
