Portable Gas Monitors

Single Gas Monitors

Tango TXi

Tango TX1

  • Tango TX1 is the first ever single gas monitor that uses two sensors to detect the same gas
  • Patent pending DualSense Technology makes users of the Tango 85 times safer
  • Three years of continuous battery runtime


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™.

CO, H2S, NO2, SO2 – Electrochemical sensor technology


GasBadge® Pro

Available Sensors: Cl2, ClO2, CO, CO/H2 Null, H2S, HCN, NO2, NH3, O2, PH3, SO2

  • Interchangeable “smart” sensors monitor oxygen or any one of many toxic gases
  • One year datalogging capacity (minmum)
  • Standard STEL and TWA
  • Docking Station™ compatible
  • Lifetime warranty

Built to Industrial Scientific’s highest quality and reliability standards, GasBadge® Pro provides a lifetime of gas hazard protection with more features than any other single gas monitor available. Interchangeable “smart” sensors enable the GasBadge® Pro to be quickly adapted to monitor unsafe levels of oxygen or any one of the following toxic gases: carbon monoxide, hydrogen sulfide, nitrogen dioxide, sulfur dioxide, chlorine, chlorine dioxide, phosphine, ammonia, hydrogen cyanide and hydrogen.

GasBadge® Pro communicates directly via an infrared interface to optional accessories like the Docking Station™, Datalink and infrared printer to further simplify and automate calibration, function (bump) testing and data downloading. Standard STEL and TWA readings, and datalogging of up to one year of survey data are featured along with an event-logger that records the past 15 alarm events.

Housed in a rugged enclosure, the monitor is immune to RF, water resistant and extremely durable. A protective concussion-proof overmold protects the unit from extreme abuse in a variety of harsh industrial environments. Its simple and intuitive four-button navigation allows easy access to setup, operation and calibration functions.

Lifetime warranty.

Get ready to see hazardous levels of oxygen, toxic and combustible gas, and volatile organic compounds (VOCs) like never before. The MX6 iBrid™ is more than an intelligent hybrid of Industrial Scientific’s best monitoring technologies. It’s the first gas monitor to feature a full-color LCD display screen.

The display improves safety with clear readings in low light, bright light or anywhere in between. Whether the work is outside, inside or underground, it’s easy to see what gas hazards lurk in the immediate work environment. And a color display is more than eye-catching. It allows the user to step through instrument settings and functions with an intuitive menu and the instrument’s five-way navigation button. It even supports the option of on-board graphing for easily interpreted direct readings and recorded data.

Plus, the MX6 iBrid is our most rugged instrument ever. It carries a lifetime warranty and is fully compatible with our DS2 Docking Station™ and iNet™ Instrument Network.
