Testo 420DP is used for volume flow measurements, Pitot tube measurements and pressure measurements for air conditioning and ventilation systems. Measuring ranges: Flow velocity: 0 to 14 m/s, Pressure (absolute pressure):70 to 110 kPa, Pressure (differential pressure): -120 to +120 Pa. Resolution: Flow velocity: 0.01 m/s, Volume flow: 1 m³/h, Pressure (absolute pressure): 0.1 hPa / 0.1 mbar / 0.01 kPa, Pressure (differential pressure) 0.00001 hPa / 0.00001 mbar / 0.0001 mm H2O / 0.000001 inH2O.
Storage temperature: -20 to +60 °C, Operating temperature: -5 to +50 °C
