about M40 FOUR-GAS MONITOR

Industrial Scientific is pleased to offer the M40, a versatile multi-gas monitor capable of detecting CO, H2S, O2, and combustible gases for a wide variety of hazardous and confined space applications. The M40 is housed in a rugged, impact-resistant case to provide superior performance and durability in harsh environments and resistance to radio-frequency and electromagnetic interference. Its four-button interface provides simple, intuitive operation and calibration, and the M40’s five-second “Off” feature prevents unintentional shut-offs. The unit’s compact size and economical price make it an ideal personal monitoring instrument. Other standard features include a vibrating alarm, lithiumion battery, peak/hold readings, large LCD, 75 hour datalogging capacity, and belt clip. An optional compact parasitic sampling pump enables remote sampling from up to 50 feet away. The M40 carries a two-year warranty.
