Tango TX1

By wearing the Tango TX1, your workers will be the safest single gas monitor users in the world. A 3-year runtime and patent pending DualSense Technology increases 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 three years. After the battery can no longer support instrument life, it can be replaced for another three 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.


3.6 V Primary lithium-thionyl chloride (Li-SOCl2), 1.5AH, 2/3AA, replaceable, nonrechargeable

How to calibrate the Tango TX1

How to calibrate your Tango TX1:

  1. Prep cylinder by connecting an open regulator to the valve end of your gas cylinder. turn off the gas once the regulator is connected.
  2. Attach tubing with Tango calibration adaptor to the regulator
  3. Once cylinder is prepped pick up your Tango TX1. Press and hold power button on the left.
  4. Once your Tango is in normal reading mode press the power button (2) times and press the enter button on the right. This puts the monitor into zero reading mode.
  5. Once your Tango passes zero, press the power button to put the monitor into calibration mode.
  6. Connect the calibration adaptor to your Tango TX1 and turn the gas on from your regulator.
  7. Once calibration is complete, turn off the gas, and take the calibration adaptor off the monitor. Wait for the monitor to go back down to zero.
