Product information

  • The Model 105 is an analyzer for the measurement of hydrogen (H2) in the workplace. This analyzer is unusual since it is easy to calibrate, has a fast
    response and has only one step to send logged data to a PC.
  • It uses a thermal conductivity sensor for the measurement of ppm or % levels of hydrogen. It has many unique features. It can also be used as a helium leak detector with a different calibration.
