Detailed Description

JCB4 portable methane detection alarming device The main function JCB4 portable methane detection alarming device, it is a kind of by single chip microcomputer technology of intelligent instrument. Completely according to AQ6207-2007 portable carrier catalytic methane detection alarming device "design and production. Mainly used in portable monitoring of coal mine methane gas concentration in the workplace. Main technical indicators Alarming device adopts natural diffusion sampling method. Alarming device using three digital tube, expressed in percent volume concentration measurements, resolution not less than 0.01% of CH4, using digital pipe display positive and negative value point representation. Alarming device display without single chip microcomputer artificial adjustment, can show the methane concentration below 0.1% CH4. With sound and light alarm alarming device self-checking function and emergency alarm, battery voltage. On methane concentrations over measurement range limit, alarming device has the function of protecting carrier catalytic element and keeping alarming device display value of the overrun. Power supply and charging Alarming device using battery has no "memory effect" of nimh batteries. Alarming device with a power supply voltage display, undervoltage hint, undervoltage automatic shutdown function. Measuring range: 0.00 ~ 4.00% CH4 basic error: 0.00 ~ 1.00% CH4 ± 0.10% CH4 1.00 ~ 3.00% CH4 true value ± 10% 3.00 ~ 4.00% CH4 ± 0.30% CH4 Alarming device battery normal charge after the working time is not less than 12 h. Response time (T90) response time is not more than 20 s alarming device. Madery Jining Hengwang Mining Machinery Co., Ltd.
