Description
testo 420 airflow capture hood - Rapid measurements of airflow in large rooms and swirl outlets Volume flow is frequently measured at swirl outlets, and airflow measurements are often incorrectly measured due to the turbulent air from these outlets. The testo 420 volume flow capture hood with its removable control unit offers a convenient solution for measurements of flow velocity, volume flow, absolute pressure, temperature and relative humidity in large rooms and swirl outlets. Automatic zeroing ensures a higher accuracy for low pressure. Technical Data: TEMP measuring range: -4° to 158 °F / -20 to +70 °C Accuracy: ±1 °F (32° to 158 °F) / ±0.5 °C (0 to +70 °C) / ±1.4 °F (-4° to 32 °F) / ±0.8 °C (-20 to +0 °C) Humidity measuring range: 0 to 100 %rH Accuracy: ±1.8 %rH + 3 % of mv at +77 °F / ±1.8 %RH + 3 % of mv at +25 °(5 to 80 %rH) Differential Pressure measuring range: -0.480 to 0.480 InH₂O / -120 to +120 Pa Accuracy: ±2 % of mv + 0.002 InH₂O at +72 °F, 405 InH₂O / ±2 % of mv + 0.5 Pa at +22 °C, 1013 hPa Absolute pressure measuring range: 280 to 440 InH₂O / 700 to 1100 hPa Accuracy: ±1 InH₂O / ±3 hPa Volume flow measuring range: 24 to 2354 CFM / 40 to 4000 m³/h Accuracy: ±3 % of mv + 7 CFM at +72 °F / ±3 % of mv + 12 m³/h at +22 °C; 405 InH₂O (50 to 2060 CFM) / 1013 hPa (85 to 3500 m³/h) Dimensions: 24 x 24 in.
