Infiltec DM5 Dual Digital Micro-Manometer, 
range 30 inch wc or 7500 Pascals,
resolution 0.01 inch wc or 1 Pascal, auto-zero, accuracy 1 percent of reading,
calibrated for Pitot flow measurements The DM5 is a portable dual digital
manometer with the easy-to-use 0.01 "wc
or 1 Pa resolution, and a range of 30 "wc
or 7500 Pa range. It is calibrated for a
wide range units for pressure and Pitot
tube flow measurements.
