Udyogi Portable Gas Detector M40 Multi Gas Detector

Industrial Scientifi c 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 confi ned 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, lithium-ion 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.
