TGS1820/World leader in gas sensing innovation

Coming soon Figaro Acetone Sensor TGS1820 Acetone gas sensor ideal for measuring fat-burning effects


  • High sensitivity and selectivity to acetone
  • Low interference from ethanol and hydrogen
  • Quick response
  • Compact
  • Low power consumption


  • Acetone detectors
  • Breath acetone testers

Figaro Engineering Inc. would like to make the following announcement:

Our brand new TGS1820, a highly selective and quick responding acetone sensor, is in the final stage of development and is set for release in the near future.

TGS1820 is a hot wire semiconductor type gas sensor. The sensing element consists of a noble metal coil embedded in a small bead of sintered metal oxide semiconductor material. Electrical conductivity change caused by gas adsorption on the MOS material surface can be measured between both ends of the noble metal coil as a change in the combined resistance of the MOS material and the noble metal coil.

TGS1820 has high sensitivity to acetone with small interference from ethanol and hydrogen. This feature makes the sensor ideal for breath acetone analysis.

For sensor evaluation, the EM1820 evaluation module will be also released soon.
