Product Specification
Air Contaminants sensor TGS2600 description
The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to
the gas concentration.
The TGS2600 has high sensitivity to low concentrations of gaseous air contaminants such as hydrogen and carbon monoxide which exist in cigarettesmoke. The sensor can detect hydrogen at a level of several ppm.Due to miniaturization of the sensing chip, TGS 2600 requires a heater current of only 42mA and the device is housed in a standard TO-5 package.
Air Contaminants sensor TGS2600 Features:
* Low power consumption
* High sensitivity to gaseous air contaminants
* Long life and low cost
* Uses simple electrical circuit
* Small size
Air Contaminants sensor TGS2600 Applications:
* Air cleaners
