Research has proven that the Zero Pressure Compensation method is the single most accurate way of measuring the airflow of supply and exhaust apertures of various shapes and sizes. The DIFF uses a built in fan & pressure compensation to deliver accurate results, every time.
Availability: 2-3 Weeks
The DIFF, a Zero-Pressure Compensation device, is used for the automatic measurement of air volume from supply and extract apertures. This instrument relies on the principal of zero pressure compensation, and therefore using the built in fan and pressure compensation, the DIFF delivers the performance and accuracy expected from commissioning engineers.
The DIFF has been Designed to be self-adjusting for supply and extract systems. The instrument can automatically detect the direction of flow once the DIFFs’ square 250mm aperture has been secured in place over the grille. The unit also features an adjustable display arm which not only allows flexible operation, but it also enables the system to be read from almost any angle.
