Flow Detective™ Air Flow Calibrator

The Flow Detective™ is an easy to use all-in-one airflow calibrator that is suitable for all types of air sampling pumps and other applications for flows up to 5L/min. It is a rugged, compact lab or field portable calibrator which removes the need to purchase multiple flowmeters. This minimizes set up prior to undertaking calibrations, and saves on purchasing costs and valuable time to undertake pump calibrations.

It calibrates any air sampling pump within airflows 20mL/min (Plus model) to 5,000 mL/min, to ensure correct flow with automated traceable measurements in order to reduce the risk of errors. With its wide flow range, as well as calibrating dust sampling heads, it can be used to calibrate at low flows for sorbent tube sampling, so ensuring just one device is needed for all personal air sampling calibrations. The innovative device enables tagging pre and post calibration data, so users can see deviations before and after measurements.

The Flow Detective™ is the first calibrator on the market that ensures that your air sampling pump complies with ISO13137’s requirements for maximum pump pulsation. As pumps generally use a moving diaphragm, this creates fluctuations in the flow rate on a pump. As sampling heads like cyclones rely on a steady flow to maintain a specific size cut, it is important for pulsation to be as small as possible. The Flow Detective™ displays a red indicator if pulsation is above 10%.
