GMV-2021B hydrogen sensor is a gas sensor based on all solid state MOS principle of advanced MEMS architecture. Hydrogen in the environment will lead to the change of MOS conductivity, which is an exponential function of hydrogen concentration.

Application

  • Hydrogen fuel cell automobiles,electric vehicles EV
  • Energy storage lithium battery pack /power station
  • Energy storage battery / power station
  • Hydrogen detection in other scenarios

Features

All solid state, lightweight, low power consumption, long life, excellent anti-interference capability.
