CJR100 / 5H infrared measuring methane carbon dioxide

I. Overview 1 Features: CJT4 / 1000 methane determination of carbon monoxide (hereinafter referred to as the measuring device) using thermal catalytic principle, electrochemical principle, embedded microcontrollers intelligent control, four digital display electronic measuring device. Mainly used for coal mine methane inspector, ventilation member, team leader, captain, engineering and technical personnel, under mine cadres Blasters carry, methane, carbon monoxide detection and alarm continued. 2, product performance standards GB 3836-2010 for explosive gas atmospheres - electrical equipment AQ 6207-2007 portable carrier catalytic methane alarm detector MT 703-2008 Mine portable electrochemical carbon monoxide measuring device Q / SD 077-2012 CJT4 / 1000 methane, carbon monoxide Determination of Enterprise Standard 3, the use of environmental conditions - Ambient temperature: -5 ℃ ~ 40 ℃; - Relative humidity: ≤95% (+ 25 ℃); - Atmospheric pressure: (80 ~ 116) kPa; - No significant vibration, shock and watering places; - have a dangerous mixture of methane gas and coal dust explosion in coal mine. - Storage temperature: -40 ℃ ~ 60 ℃. 4, explosion-proof type and explosion-proof mark - proof type: Mine intrinsically safe and explosion-proof; - proof mark: Exdib I Mb Second, the principle of the measuring device from the chassis, sensors, circuit boards, batteries and other components. Real-time detection of the surrounding ambient air methane, carbon monoxide concentration measuring device after boot, and by four digital display in digital form, by pressing the shift key to switch the display. When the methane concentration exceeds the alarm set point, the measuring device and audible alarm signals, and displays the current concentration of methane. When the carbon monoxide concentration exceeds the alarm set point, the measuring device alarm audible and visual alarm signals, and displays the current value of carbon monoxide. When the concentration of methane and carbon monoxide safety while exceeds the set value, measuring alarm sound and light alarm signal, and alternating readings of methane and carbon monoxide. To protect the black and white catalytic components, when the measuring device detects the ambient concentration of methane than or equal to 4.00%, the measuring device off the power catalytic combustion of black and white elements, and the police. Third, the major technical indicators No. Project: Performance indicators 1, measurement range: CH4 CO 0.00-4.00% 0 ~ 1000 × 10-6 2, the measurement error: 0 ~ 1.0% CH4: ± 0.1% CH4 1% ~ 2.0% CH4 : true value ± 10% CH4 2.0 CH4% ~ 4.0%: ± 0.3% CH4 (0 ~ 20) × 10-6 CO, is not greater than ± 2 × 10-6 CO (0 ~ 100) × 10-6 CO, not more than ± 4 × 10-6 CO (100 ~ 500) × 10-6 CO, is not more than ± 5% measured value (500 ~ 1000) × 10-6 CO, is not more than ± 10% measured value 3, alarm point: CH4: arbitrarily set within the range of 0.50% CH4-2.50% CH4, the factory default setting is 1.00%.
