Hot-wire Semiconductor (CH)

hot-wire-semiconductor

Our Hot-wire Semiconductor detects changes in resistance across the edges of platinum wire as a result of variations in thermal and electrical conductivity due to absorption of gas on the surface of a semiconductor.

 

 

 

 

Features:

  • Sensitive and large variation in output at low gas concentration
  • Shorter initial stabilization time, more compact, and greater energy savings compared with a semiconductor sensor
  • Long service life, high stability, and high durability
  • Selective sensitivity to gases (H2, CH4, and C2H5OH)
