*At standard flow and 20°C (68°F) the measurement error (±0.2%) is determined
**Minimum dial division

The maximum gas inlet overpressure is dependent on the casing material: With plastic casings: 50 to 500 mbar / With SS casings: 0.5 to 35 bar
At standard flow and 20°C (68°F) the measurement error (±0.2%) is determined.
