Tango TX2

Two Gases. Individual Sensors. Fewer False Alarms.

When a site requires monitoring of two gases simultaneously, the choice of instrument matters more than most people realise. Many two-gas monitors use combination sensors, a single sensing element that attempts to detect both target gases at once. The problem is that combination sensors are more susceptible to cross-sensitivity, where the presence of one gas affects the reading of the other, leading to false alarms. Unplanned shutdowns caused by false alarms cost time, money and erode worker trust in the gas detection system itself.

The Tango TX2 takes a different approach. It uses two individual sensors, one dedicated to each gas, processed independently and displayed either alternately or on demand. Because each sensor is only responding to its own target gas, alarm accuracy is higher, false alarm rates are lower and the data collected during an alarm event is more reliable for post-incident analysis.

Simplicity at the Core

The Tango TX2 is designed for workers, not safety managers. It is the size of a credit card, weighs less than a smartphone and operates for two years on a single replaceable battery. There is no charging station to manage, no daily battery checks and no downtime for charging between shifts. The two-button interface and segment LCD display keep operation straightforward, with the display configurable to show the first sensor reading, the second sensor reading or to alternate between both every three seconds.

When any sensor goes into alarm, the display automatically alternates between readings regardless of the configured display preference, ensuring the worker always has full visibility of both gas concentrations during an alarm event.

Maintenance That Fits Into Your Operation

The Tango TX2 is compatible with Industrial Scientific’s DSX Docking Station, which automates calibration, bump testing and data upload when the instrument is docked. For organisations that prefer to eliminate fleet management entirely, the Tango TX2 is also compatible with iNet Exchange, Industrial Scientific’s gas detector subscription service that ships replacement monitors directly when needed.

Sensors are interchangeable, if you need to switch from one gas configuration to another, the Tango TX2 detects the new sensor configuration immediately upon installation.
