With the help of a calibration ampoule you can conduct an on-site calibration to test your carbide meter.
Here you are the explanatory videos for your
mechanical manometer:
digtal manometer:
After the chemical reaction has finished, you should be able to measure a pressure of 1 bar at 20˚C when using 1 gram of reacting water. The allowed deviation lies at 5% off of the set pressure and needs a respective bottle volume. The maximal deviation consists of
- ± 1% of the bottle volume: max. allowed deviation (of a Radtke-Measuring Instrument)
- ± 1% of the calibration ampules: max. allowed deviation (of a Radtke-Measuring Instrument)
Allowed faults of the manometer
- ±2.5% of mechanical manometer (CLASSIC and ECO) is the max. allowed fault at a pressure of 1 bar, leave or take ± 0.5% allowed deviation at a temperature of 20˚C
- ±0.4% of digital manometer (BUSINESS) is the max. allowed fault at a pressure of 1 bar, leave or take ±2.6% allowed deviation at a temperature of 20˚C
