Tango^® TX1 Single-Gas Detector

Wearing the Tango TX1 single-gas monitor with DualSense™ Technology makes you one of the safest single-gas monitor users in the world. Using redundant sensors for detection of the same gas eliminates the pain of balancing cost, safety, and bump test frequency. Additionally, with a two-year battery life, the costs of monitor replacement are eliminated and downtime is reduced.

DualSense™ Technology uses two of the same sensors for detection of a single gas. Readings are passed through a proprietary algorithm and a single monitor reading is displayed. This decreases the likelihood of a monitor not being able to detect gas out in the field, making DualSense monitors safer than single-sensor monitors.

The Tango TX1 single-gas monitor uses sensor redundancy, reducing the likelihood of the monitor’s inability to detect gas. Below is a chart that shows the monitor failure rate of a single sensor monitor versus a monitor with DualSense Technology when bump tested daily or not bump tested at all. In either case, the Tango TX1 single-gas monitor elevates the level of safety regardless of the customer’s current bump test policy.

                                      Single-Sensor            DualSense Technology

Daily Bump Test        Failure is 1 in 1,265    Failure is 1 in 116,257 — 92 Times Safer

No Bump Testing      Failure is 1 in 286      Failure is 1 in 21,319 — 74 Times Safer

Yes. A worker will still be protected and can continue working in the field if the sensor fails. Because of sensor redundancy, if a sensor were to fail in the field, the monitor will still continue to operate normally. In addition, if a sensor fails a calibration or a zero fault has occurred, the Tango TX1 single-gas monitor will operate the same as any other single-sensor monitor would.

Yes. Sensors are changeable, allowing the user to convert the Tango TX1 single-gas monitor from one gas type to another.

No. The primary advantage of DualSense™ Technology would be lost if converted to a two-gas monitor. If you are looking for a two-gas monitor, check out the Tango TX2.

The Tango TX1 single-gas monitor is Guaranteed for Life™ to ensure customers always have the highest quality monitor.

Guaranteed for Life™. Warranted for as long as the monitor is supported by Industrial Scientific Corporation (excludes sensors, batteries, and filters). CO and H2S sensors are warranted for three years. All other sensors are warranted for two years.
