America intrinsic M40 • M coal mine special four gas detection instrument
M40 • M coal mine special four gas detection instrumentin detail:
M40 • M multi gas detector can be used in coal mine,mine operations or other work environment, to ensure that personnel are not affected by hypoxia (O2) andperoxynitrite, dangerous levels of gas (methane gas,toxic gas of carbon monoxide (CH4) CO), hydrogen sulfide (H2S) harm. The instrument has been China coal mark (MA).
M40 • M with strong shockproof, anti shock, fire enclosure, providing high performance and durability in harsh environments, with no interference from radiofrequency and electromagnetic. Operation andcalibration is simple, sensitive and can be the key typeinterface, 5 seconds "delay" function to prevent accidental shutdown. Other standard features include:vibration and sound and light alarm device, 50 hours ofdata record (black box), the performance of lithium ion rechargeable battery, the peak / keep reading, large screen liquid crystal display, special protective case.Integrated compact sampling pump (optional) can realize remote within 15 meters of the sampling detection.
Shell:
