One User specific measuring range

The unit will offer with ranges between 100 ppm – 10% of hydrogen.

 

Sensor

The H2Trans uses a special fuel cell to measure the hydrogen concentration. The sensor meets the industrial requirements for accuracy, sensitivity, easy to use and operating life.

 

Calibration

The calibration of the instrument for trace hydrogen measurements in gas, should be done with a calibration gas. The concentration
can be chosen freely within the measuring range. In the percent range the unit can calibrated with air.

 

Features

  • compact
  • inexpensive
  • Sensor with long operating life
  • IP65 enclosure
  • reverse voltage protection and temperature compensation

 

Flow-through measuring cell in Stainless Steel

  • The measuring cell is modular and is made of stainless steel
  • A defective measuring cell can be repaired by replacing the defective part only, rather than the complete unit
