It's with the diffusion sampling mode, can be connected with the external pump. The portable gas detector can promise the security for the personnel working under the toxic gas in the harmful environments.

Gas Detector TechnologiesMeasurement of Toxic GasesMeasurement of Combustible GasesCommon Gas Detector ApplicationsAdditional Gas Detector InformationOther Detectors ArticlesGas detectors are categorized by the type of gas they detect: combustible or toxic. Within this broad categorization, they are further defined by the technology they use: catalytic and infrared sensors detect combustible gases and electrochemical and metal oxide semiconductor technologies generally detect toxic gases.See more on thomasnet.comConsiderations for intrinsically safe batteries ... 01, 2009During an emergency, power to coal mines is typically shut off to reduce the risk of methane gas ignition and the obvious danger to the miners underground. In this situation, the system is completely reliant on power from Saft single-cell MP Series batteries. Alion Science and Technology developed an IS handheld radio for underground coal mines.

OC-904A Portable multi gas detector used to detect the gas concentration in many applications, including of the chemical industry, petroleum, gas station, metallurgy, agriculture, biology pharmaceuticals, power, lab research and other industry environment where need to inspect combustible or toxic gas concentration.

Whatever type of system you choose, make sure you understand what the monitor will and will not do. Most of these monitors are for surveying and not for accurate readings. OSHA only requires a 25% error, so do not plan to use any of these monitors for laboratory analytical work.
