• READINGS CORRECTED FOR AIR DENSITY
AIR FLOW:
Measured in cubic feet per minute (cfm) and litres per second (L/s) corrected for local air density. The measurement range is 25-2500 cfm supply and 25-1500 cfm exhaust. Accuracy is ±3% of reading ±7 cfm from 100 to 2000 cfm.
AIR DENSITY CORRECTION:
The air density correction range is 14-40 in Hg and 32ºF to 158ºF for correction of air flow measurements. The readings represent local density airflow corrected for the density effects of temperature and absolute pressure.
RESPONSE TIME:
Five seconds for air flows greater than 180 cfm, and up to eight seconds at less than 70 cfm.
POSITION SENSITIVITY:
Unaffected by position.
READOUT:
10 digit, 0.4", high contrast, liquid crystal display.
WEIGHT:
FlowHood unit with meter and 2'x2’ top, 9.7 lbs.
UNIT DIMENSIONS:
Height 40"; top 24"x24"; base 14"x14".
BATTERY LIFE:
3000 readings per charge, 500 recharge cycles.
