Sulfur dioxide (SO2), R 764
For our measurement sensor for determining the concentration of Sulfur dioxide, we offer the following calibration gases.
| Usage | Explanation |
|---|---|
| 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 70% to 100% of the full scale value of the probe. |
| Alarm test gas | The alarm test gas is required to verify the alarm levels. |
Select the measuring range of your probe:
