Velocity Datalogger

PROFILE Stack Velocity Datalogger


The Profile is a portable handheld microprocessor based instrument that enables the operator to determine the velocity profile in a duct or stack. It achieves this by measuring the temperature and differential pressure in a flowing air or gas stream. It also measures the ambient pressure and temperature and logs all the data recorded on a point by point basis.

The Profile will log up to 20 separate tests and store the point by point sample information for up to 4 traverses, along with the averages for each traverse. Once collected the information can be displayed on the Profiles own screen or downloaded to a PC for data processing and report generation.
