The M40’s rugged composite case is immune to RFI, and houses four discrete sensors, a large LCD readout, and integral lithium-ion battery for up to 18 hours continuous runtime.
• The M40 continuously monitors oxygen, combustible gases, carbon monoxide, and hydrogen sulfide in any combination, activating bright alarm light, 90-dB audible and internal vibrating alarms when gas concentrations exceed the preset limits. Additional standard features include Peak/Hold functions, STEL and TWA readings, a continuous loop datalogger and ‘Quick-Cal’ calibration.
• The M40 comes standard 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 Mcal automatic calibration station. Weighing 8.6 ounces, the M40 is small in size and big in value.
