Figaro’s TGS5042 is a battery operable electrochemical sensor which offers several advantages over traditional electrochemical sensors. Its electrolyte is environmentally friendly, it poses no risk of electrolyte leakage, can detect concentrations as high as 1% CO, operates in a range from -5˚ and +55˚C, and it has lower sensitivity to interferant gases. With a long life, good long term stability, and high accuracy, this sensor is the ideal choice for CO detectors with digital display. OEM customers will find individual sensors data printed on each sensor in bar code from, enabling users to skip the costly gas calibration process and allowing for individual sensor tracking. TGS5042 utilizes a standard AA battery-sized package.


The figure below represents typical sensitivity characteristics, all data having been gathered at standard test conditions (see reverse side of this sheet). The Y-axis shows theoutput current of the sensor (Iout/μA) in each gas. Output current is linear to CO concentration, with a deviation of less than ±5% in the range of 0~500ppm.

Sensitivity Characteristics:

 


The figure below represents typical temperature dependency characteristics. The Y-axis shows the sensor output ratio (I/Io) as defined below. The linear relationship between I/Io and CO concentration is constant regardless of the CO concentration range.
I = Sensor output current in 400ppm of CO at various
temperatures
Io = Sensor output current in 400ppm at 20˚C/50%RH

*1) Represents sensor output in air under operating conditions
(*2) If the water in the reservoir should freeze very rapidly (typically occurs only under artifically created conditions), irreversible change to sensor characteristics would occur. To avoid this risk, the sensor is recommended to be positioned with its cap (working electrode) facing up.
(*3) Please contact Figaro for more information if the required temperature range would exceed the specified limits.
