Low-Cost M40 Multi-Gas Monitor Provides Industrial Strength Features

PITTSBURGH -- Industrial Scientific Corporation introduces the M40, a versatile multi-gas detector capable of measuring carbon monoxide, hydrogen sulfide, oxygen and combustible gases for a wide variety of confined space and personal monitoring applications. Built with the durability and simplicity found in every Industrial Scientific instrument, the M40 is a reliable, low-cost alternative for simultaneous monitoring and display of any configuration of one to four gases.

The M40's rugged composite case is immune to radio frequency and electromagnetic interference, and houses four discrete sensors, a large LCD display, and rechargeable lithium-ion battery for up to 18 hours of continuous runtime. When gas concentrations exceed preset limits, the M40 monitor alerts the user with the bright visual and 90-dB alarms, and activates the internal vibrating alarm for high-noise environments.

Standard features include a continuous-loop datalogger, peak/hold functions, STEL and TWA readings and 'Quick Cal' calibration. Each M40 monitor comes equipped with a charger, nylon carrying case, cell-phone belt clip and calibration cup with tubing. Available accessories include SP40 motorized remote sampling pump, 12 VDC automobile charger, M40 datalink, and complete confined space kits. Weighing just 8.6 ounces and carrying an all-inclusive 2-year warranty, the M40 is small in size and big in value.

The M40 monitors carry the UL and CSA approvals for Class I, Groups A, B, C, and D hazardous locations, and Cenelec (ATEX) and Australian certification approvals (Ex ia IIC T4).

Industrial Scientific Corporation is a leading designer, manufacturer and marketer of gas monitoring instruments, systems and other technical products for the preservation of life and property. The company has headquarters in Oakdale, Pa. and 28 regional offices throughout the world.
