TECHNICAL INFORMATION FOR TGS5042
Technical Information for Carbon Monoxide Sensors
Figaro’s TGS5042 is a battery operable
electrochemical sensor which offer 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 -40˚ and +70˚C, and it
has lower sensitivity to interference 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.
