Tango TX2

Tango TX2 Two Gas Detector, Carbon Monoxide (0 to 1,000 ppm in 1 ppm increments) and Nitrogen Dioxide (0.0 to 150.0 ppm in 0.1 ppm increments) Protect workers, reduce false alarms, and spend less time managing your gas detector fleet. The Tango TX2 uses individual sensors to increase alarm accuracy so you can reduce unnecessary shutdowns and improve incident data quality. A two-year runtime from a single, replaceable battery eliminates the need for charging.
