Lower price than the two-eleven! Lower prices than the Chinese Lunar New Year! Why so cheap? Factory outlets, prices! Of course, more than two-eleven, at lower prices than the Chinese New Year, better the company's products, many different types, but also for a wide range, with intrinsically safe high-quality products, and this product is one of the flagship products of our company, set up in the country and more with subsidiaries and offices, while products are well recognized in line with the national security inspection certificate. Such products are mostly mining, roadway, as well as high-risk places to use! Therefore, these products must be regular, qualified, excellent quality of high-quality products. Here is an overview of our products, one of these products! ? A, CJYB4 / 25 methane - oxygen dual parameter Alarm Overview: Model: CJYB4 / 25 CJYB4 / 25 methane - dual alarm device is the use of an oxygen inlet pressure compensation type oxygen sensor and catalytic methane heat sensitive components (commonly known as black and white elements ) intelligent portable instrumentation. ? Two, CJYB4 / 25 methane - oxygen dual parameter Alarm Applications methane, carbon monoxide detectors measure the concentration of methane in the air and the oxygen concentration in the coal mine for each workplace. Instruments to measure the oxygen concentration with depth-independent, without correction for elevation. The instrument has sound and light alarm function; over-range automatic shutdown function; battery voltage display; undervoltage auto-off function; automatic charging and battery protection. ? Three, CJYB4 / 25 methane - oxygen dual parameter Alarm parameters:? Measuring range: Oxygen: (0.0 ~ 25.0)% O2 methane: (0.00 ~ 4.00)% CH4 basic error: Methane: (0.00 ~ 1.00)% CH4 When, ± 0.10% CH4 (1.00 ~ 3.00)% CH4, the true value ± 10% (3.00 ~ 4.00)% CH4 when, ± 0.30% CH4 Oxygen:?? (0.0 ~ 5.0)% O2 time, ± 0.5? % O2 (5.0 ~ 25.0)% O2 when, ± 3% FS Alarm:? audible and visual alarm display: four LED display turns methane and oxygen concentrations. ?
