Tango TX1

The Single Gas Detector That Keeps Working Even When a Sensor Fails

The Tango TX1 by Industrial Scientific is built on a simple but powerful idea: what if your single gas detector kept protecting you even if one of its sensors failed? That is exactly what DualSense Technology delivers. By installing two sensors of the same type in a single instrument, the Tango TX1 provides a level of redundancy that no conventional single-sensor gas detector can match.

The two sensor readings are processed through a proprietary algorithm and displayed as a single reading to the user. If one sensor fails in the field, the instrument continues to operate normally using the remaining sensor, keeping the worker protected without interruption. This approach has been validated against real-world bump test data collected through Industrial Scientific’s iNet platform, confirming that DualSense Technology significantly reduces the risk of undetected sensor failure compared to single-sensor instruments, regardless of the user’s current bump test policy.

Always On, Always Ready

The Tango TX1 operates in always-on mode for up to two years on a single battery, eliminating the need for daily charging. When the battery reaches the end of its life, it is user-replaceable, allowing the instrument to continue operating for another two years. Combined with the Guaranteed for Life warranty on the instrument itself (excluding sensors, batteries and filters), the Tango TX1 is designed to deliver long-term value without the replacement cycle that typically drives up fleet costs.

CO and H2S sensors carry a three-year warranty. All other sensor types carry a two-year warranty.

Loud, Clear and Impossible to Ignore

The Tango TX1 alarms at 100dB at 10cm, making it one of the loudest single gas detectors available. For even noisier environments, the optional AlarmAmp accessory increases the audible alarm to 110dB. Three strobe-emitting visual alarm LEDs, two red and one blue, combine with a built-in vibration alarm to ensure workers are alerted through multiple channels simultaneously.

The instrument’s multi-plane sensor ports sample air from three directions, promoting continuous gas detection even if one or two of the sensor inlet planes become partially obstructed.

Data Logging and Fleet Management

The Tango TX1 logs data continuously at 10-second intervals, storing approximately three months of readings. The event log records up to 60 alarm events, 30 error events and up to 250 calibration and bump test records, all date and time stamped. Data is downloaded when the unit is docked in a compatible DSX docking station, making fleet management and compliance record-keeping straightforward.
