CLH100 mine explosion measuring hydrogen sulfide hydrogen sulfide sensor mine detector CLH100 hydrogen sulfide hydrogen sulfide measuring device Product Description: The product is a new generation of miniature intelligent detector, can continuously detect the presence of flammable, explosive and flammable gas mixture environment The concentration of hydrogen sulfide. With sound and light alarm, clock, voltage display, low voltage alarm, automatic zero tracking, adjustable, easy to use features. CLH100 hydrogen sulfide measuring device Main features: CLH100 hydrogen sulfide measuring device (hereinafter referred to as instrument) using electrochemical sensors, embedded microcontrollers intelligent control, four LED display. Small size, light weight, simple operation, easy maintenance, instrument uses membrane touch switches, sealed performance is good, accurate and reliable. This instrument is widely used in the coal mine, metallurgy, environmental protection, on-site presence of explosive mixtures of flammable gases such as working environment of continuous monitoring of the concentration of hydrogen sulfide and overrun sound and light alarm. Measuring range: 0 ~ 100 × 10-6H2S alarm point: 0 ~ 100 × 10-6H2S continuously adjustable (factory set 20 × 10-6H2S) Response time: T ≤ 60s indication mode: 128 × 64 dot matrix LCD display real-time data , menus and system status LEDs and audible alarm, fault tips and undervoltage indication Operating environment: Temperature 0 ℃ ~ 40 ℃; humidity ≤ 98% RH Atmospheric pressure: 86kPa ~ 110kPa Working voltage: DC3.7V Working current: ≤ 110mA Battery Model: PL123450 Lithium Battery Battery Capacity: 1500mAh U0: 4.3V I0: 3.1A Charging time: 4h ~ 6h Sensor Life: 1 Year Protection: IP54 Weight: about 140g (including battery) Dimensions: 60.5mm × 26.5mm × 109mm Working principle: When the instrument is used to measure the hydrogen sulfide in the air, the electrochemical sensor by diffusion in the environment directly gases reaction to produce a linear change in voltage signal. Signal is amplified by the linear amplifier input in the microcontroller A / D converter converts the digital signal through the microprocessor data processing, the digital display of the concentration of hydrogen sulfide, hydrogen sulfide concentration is higher than when the alarm set points, the instrument audible alarm signal. Instrument has a low battery voltage alarm and automatic shutdown. Jining Branch-Mining Equipment Co., Ltd. Contact: Lv
