Differential pressure anemometer is a robust and durable bi-directional anemometer with no moving parts or sensing electronics. With the installed tubing, the model ANE-1 connects easily to any manometer or applicable pressure sensing device and is capable of measuring a wide velocity range. The air velocity range and accuracy is dependent on the installed manometer, and the instrument retains the accuracy as long as it is dust free. It is comprised of multiple pressure sensing ports and averages the flow across its grid providing an accurate measurement. Made from high quality ABS plastic, it comes with a versatile handle, two 5 foot sections of coloured tubing, and a tubing adapter. Complete details are available here.
