This multi gas monitor is configured for Oxygen (O2) and Combustible Gases (LEL)
Features & Applications:
Industrial Scientific is pleased to offer The M40, a versatile multi-gas monitor capable of detecting Oxygen (O2), and combustible gases (LEL) 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, lithium-ion battery, peak/hold readings, large LCD, 50 hour datalogging capacity, and belt clip. An optional compact parasitic sampling pump enables remote sampling from up to 50 feet away.
Features:
- Monitoring for Oxygen (O2) & combustible gases (LEL)
- 18-hour runtime with lithium-ion battery
- Includes vibrating, 90dB audible, and LED visual alarms
