Guoqiang CD4 portable multi-parameter measuring device

I. Overview 1, product features ultra-portable multi-parameter measuring CD4 (hereinafter referred to as the tester) is a supported catalyst component, electrochemical principle sensors, embedded microcontroller chip and LCD display consisting of an electronic measuring device. Real-time detection of ambient air methane, oxygen, carbon monoxide, hydrogen sulfide concentration of four gases, but also has the date, time, temperature and humidity display, sound and light alarm, automatic backlight, undervoltage alarm functions; measured with small size, light weight, simple operation, easy to carry, accurate and reliable. Measuring device is widely used in the coal mine, metallurgy, environmental protection and other environmental field, it can be methane, oxygen, carbon monoxide, hydrogen sulfide monitoring, and sound and light alarm when overrun. 2, product performance standards: GB 3836-2010 "explosive gas environment with electrical equipment" AQ 6207-2007 "portable carrier catalytic methane alarm detector" MT 703-2008 "Mine portable electrochemical carbon monoxide measuring device" MT 704-2008 "Mine portable electrochemical oxygen measuring device" MT 1084-2008 "coal with hydrogen sulfide detector measuring" Q / SD 008-2012 "CD4 portable multi-parameter measuring device." Second, the main technical indicators Project: Technical specifications: CH4 (%), CO (1 × 10-6), O2 (%), H2S (1 × 10-6) alarm: the measuring range can be set at the factory is set to be set within the range of 1.00% CH4 Measurement set at the factory to be set within 24 × 10-6 CO measurement range, the factory is set to be set within the range of 18.0% O2 measurement, factory setting is 10 × 10-6 H2S Display: LCD display Alarm mode: sound and light alarm battery pack: is powered by 3 1800mAh NiMH batteries in series, with external series 1.4Ω / 16W after limiting resistor with epoxy resin encapsulated, intrinsically safe battery constituting components. Rated voltage Ue: 3.6V, the maximum operating current (alarm): ≤180mA, the maximum output voltage Uo: 4.2V, the maximum output current Io: 2.5A. Continuous working time: ≥10 hours (fully charged) voltage alarm: When the battery voltage is lower than 3.40V, the buzzer periodically issue a "beep, beep" sound prompts, when the battery voltage is lower than 3.15V, the instrument automatic shutdown, need to be recharged before use. Explosion-proof type: ExibdⅠMb mining intrinsically safe and explosion-proof. Dimensions: 65mm × 125mm × 32mm Weight: 0.5Kg Environment: Temperature: 0 ℃ ~ 40 ℃; Relative humidity: ≤98%; Atmospheric pressure: 80 kPa ~ 116 kPa; wind speed: no more than 8m / s; explosive gas Hazardous Locations mixture.
