The Tango TX1 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 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 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

* This bump test failure data is based on records collected through iNet®, Industrial Scientific’s gas detection subscription service.

Sensors are changeable, allowing the user to convert the Tango from one gas type to another.
