Tango TX2 Frequently Asked Questions

What is the advantage of using the Tango® TX2?

The Tango TX2 is the size of a credit card and weighs less than a smartphone. A two-year run time from a single, replaceable battery eliminates the need for charging infrastructure and simplifies gas detector management. Unlike other two-gas monitors that use combination sensors, the Tango TX2 uses individual sensors, increasing alarm accuracy so you can reduce unnecessary shutdowns and improve incident data quality.

When should I use a Tango TX1 versus a Tango TX2?

The Tango TX1 is best for single-gas detection using DualSense® Technology for extra coverage of a single gas hazard. If you need to monitor a second gas, you should use the Tango TX2.

What sensors does the Tango TX2 support?

The Tango TX2 can support the following sensors: CO, H2S, SO2, NO2, CO H2Low.

Are there any restrictions on sensor combinations?

Any two sensors from the supported sensor list can be combined in the Tango TX2.

Are sensors interchangeable?

The sensors are interchangeable. If you switch a sensor, the Tango TX2 will immediately detect the new configuration.

With two sensors, how do I know what gas type reading is displayed?

The TangoTX2 can display readings from sensor one, readings from sensor two, or alternate between the two readings. The default setting is for an alternating display, but users can choose to alternate the readings every three seconds or choose one sensor to be displayed. 

If I choose to display a specific sensor, what happens when the other sensor goes into alarm?

When a sensor goes into alarm, the readings alternate regardless of the display option chosen.

Does the Tango TX2 come with a warranty?

Yes, the Tango TX2 is Guaranteed for Life™ to ensure you always have the highest quality gas monitor.
