Industrial Scientific Tango® TX1 Gas Detector 

By wearing the Tango® TX1 Portable gas detector, the workers will be the safest single gas monitor users in the world. A 2-year run time and patented DualSense Technology increase worker safety, regardless of bump test frequency, while reducing overall costs. 


  • Significantly increases worker safety - DualSense Technology ensures that, regardless of your current bump test policy, you will be significantly safer with the Tango than with any other single gas instrument on the market today. *  
  • Longer battery life - Operates continuously in an "always-on" mode for two years. After the battery can no longer support instrument life, it can be replaced for another two years of continuous operation.
  • Louder instrument alarm - Alarms at 100dB at 10 centimeters making it twice the volume of Industrial Scientific's GasBadge units and louder than any single gas instrument on the market. Alarm volume can be increased by about 10dB for higher-noise environments with the addition of the optional AlarmAmp™.


DualSense Technology uses redundant sensors to determine the concentration of the target gas in the atmosphere and reduce the risk of instrument failure. Two sensors of the same type in one gas detector help to give you the most accurate gas reading.
