The Tango™ TX1 single-gas monitor from Industrial Scientific offers a three-year runtime and detects carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2) and nitrogen dioxide (NO2). Its patent-pending DualSense Technology is designed to increase worker safety, regardless of bump test frequency, while reducing overall maintenance costs. DualSense includes two of the same type sensor for the detection of a single gas. The two sensor readings are processed through a proprietary algorithm and displayed as a single reading to the user.Dual-sensing technology
