The Lumidor MicroMax Pro is the only microprocessor controlled multi-gas monitor that has it all — ease of use, reliability, high quality, economical, lightweight and with the shortest response time. The unique microprocessor design allows for self diagnostics with each start up. The Lumidor MicroMAX Pro internally data logs individual channel alarms, TWA averaging and peak information. With a push of the "Mode" button you can review information, as well as customize user settings or initiate calibration.

Calibrating the Lumidor MicroMax Pro is easier than ever before--it's all automatic--no tools, screws or stopwatch required. Simply place in calibration "Mode", introduce calibration gas and wait for the display to indicate that the calibration is complete. A NiMH rechargeable battery pack and charger are now included with each monitor.

The Lumidor MicroMAX Pro has preset and field selectable alarms. Both audible and visual alarms warn the user if the oxygen levels are either too low or too enriched, and when combustible gas or toxic gas levels are too high. The toxic gas alarms can be easily adjusted in the field from immediate to TWA. Alarms will also activate in case of sensor failure, low battery voltage, pump blockage or low air flow.

The MicroMAX Pro is designed to provide the ultimate in personal safety. It is OSHA compliant, and has a rugged case that provides superior RFI/EMI shielding, as well as dust, water and impact resistance. Additionally, the MicroMAX Pro is designed, tested and manufactured under strict ISO 9001 standards, and are UL classified for use in Class I, II, III Division I, Groups A, B, C, D, E, F, G.

Since worker safety is their business, Lumidor continually strives to improve its gas detector product line, and has done so with the addition of the voice message feature. Four languages (English, French, German and Spanish) are included with each monitor - just select the desired language. Every function, when activated, is accompanied with a voice message. Everything from immediate warnings to simple on and off functions are communicated verbally to the user. This feature is also very valuable in poorly lit situations. And, the language displayed on the new 4-line display is the same as the one selected for the voice.
