Minimax XT is the result of customer inspired partnerships. The unit is technically crafted to be, quite simply, the easiest and most cost effective to use single gas on the market. Utilizing patented sensing technologies, the Minimax XT provides 24/7 user confidence. That means solid, reliable, continuous protection... always.

Lumidor identified that the market demanded more than tiny good looks in a single gas. Our valued partners said that in addition to a small and rugged design, single gas monitors must offer comprehensive sensor options, simple operation and most importantly, reliable, and accurate readings – without false alarms triggered by common radio interference.

Simple one button operation reduces time consuming and costly training issues. Our unique Temperature Compensation and Cell Output Decay Compensation features ensure improved accuracy across wide temperature ranges, providing our 2 year, no calibration needed facility.
