By wearing the Tango™ TX1 Portable gas detector, your workers will be the safest single gas monitor users in the world. A 2-year runtime and patent pending DualSense Technology increases worker safety, regardless of bump test frequency, while reducing overall costs.
*Based on iNet® data including more than 2 million bump tests and 100,000 unique sensors.
Guaranteed for Life™. Warranted for as long as the instrument is supported by Industrial Scientific Corporation (excludes sensors, batteries, and filters). CO and H2S sensors are warranted for 3 years. All other sensors are warranted for 2 years.
