Industrial Scientific Tango TX1 [IS-TX1-2] H2S Hydrogen Sulfide Single Gas Monitor, 3 Year Warranty

The Tango TX1 is a portable, long-life, single-gas monitor (instrument) for personal protection. It is a diffusion instrument for use in detecting and measuring gas present in open space.

DualSense® Technology enables the use of redundant sensors, two installed sensors of the same type that are DualSense capable. The DualSense sensors measure the target gas concentration in the atmosphere at the same time, but operate independently of each other. Using a proprietary algorithm, the instrument 3 processes each sensor's data to display a single gas reading, while maintaining data logs for each sensor and for the derived DualSense "virtual" sensor. Each sensor will revert to operate as a single sensor in the event its redundant sensor fails. This allows the instrument to continue operation until the failed sensor can be replaced. 

The Tango TX1’s multi-plane sensor ports each sample air from three directions; this promotes continuous operation if one or two planes become obstructed. Since the TX1 measures gas at two second intervals, and continuously logs data every ten seconds, the data log can store approximately three months of data for a unit that is on 24 hours a day and has two installed, operational sensors. As the newest data are logged to memory, the oldest data are overwritten. The data log's date- and time-stamped event log records and stores event data for 60 alarm events and 30 error events. It also stores the data for up to 250 manual calibrations and bump tests. The data log is downloaded when the unit is docked in a compatible docking station. 

The instrument has two modes; configuration and operation. When in configuration mode, a unit's settings can be manually edited. Entry to configuration mode can be security-code protected. When the instrument is on and is not in configuration mode, it is said to be in operation mode.
