Hydrogen (H2)

For our measurement sensor for determining the concentration of Hydrogen, we offer the following calibration gases.

UsageExplanation
Zero gas This gas is needed for the calibration of the zero point.
Standard test gas The standard test gas is required for calibration / adjustment of the sensor with a two-point calibration. The concentration value corresponds to about two-thirds of the full scale value of the probe up to 50% LEL.
Alarm test gas The alarm test gas is required to verify the alarm levels.
