Tango® TX2 Two-Gas Monitor

Protect workers, reduce false alarms, and spend less time managing your gas detector fleet with the Tango TX2. Unlike other two-gas monitors that use combination sensors, the Tango TX2 uses individual sensors to increase alarm accuracy so you can reduce unnecessary shutdowns and improve incident data quality.
