KOMYO KITAGAWA SC-404 semiconductor gas sensor for combustible gases (diffusion method). High VOC sensitivity.

Standard measuring range:  0-500ppm

Part no: SC-404

Method: Diffusion type

DOWNLOAD DATASHEETThis diffusion type, high sensitivity hot-wire semiconductor gas sensor is for measurement of combustible gases with high VOC sensitivity.

The sensor offers high VOC sensitivity and humidity compensation with good zero and long-term stability. It is utilised for diffusion type gas detectors. 

  • High sensitivity against lower concentration VOC, so suitable for TLV alarm setting and early leak detection
  • Small zero drift, unaffected from humidity
  • Good long-term stability
  • Measuring range is from 0 to 500ppm
  • Response time within 30 seconds at 50% response (Toluene 100ppm)

Available for new gas detection applications and for sensor replacement in Komyo Kitagawa portable monitors and fixed gas detection systems.
