DIFFiner is PC software designed for use with the DIFF Automatic air volume flow meter. Together they provide a simple and very accurate solution for surveying and reporting of ventilation systems in residential and commercial buildings.

Observator Instruments are the first manufacturer to offer this unique solution. The user of the DIFF Automatic can upgrade to incorporate and work in conjunction with DIFFiner. The PC-software DIFFiner is supplied complete with a 2 GB SD card. The SD card serves as the memory card for the Diff Automatic.

The DIFF Automatic with pressure compensation can be used for calibrating, adjusting and the accurate balancing of air supply rates and exhaust rates at grilles in housing and utilities (e.g. heat recovery systems). Remember it is the technique of balancing pressure across the Diff Automatic that ensures high levels of accuracy. Applications for this technology and instrumentation are far reaching.
