FKS 1DP-PBM Meter for Air Pressure, Speed and Flow Measurements

Measures Speed, Diff / Gage Pressure, and Flow

FlowKinetics FKS 1DP-PBM meter

The FKS 1DP-PBM is a manometer, air speed meter, and air flow meter with on-board logging capabilities. The FKS 1DP-PBM meter has unmatched ease of use due to its prompt driven user interface and intuitive operation. It is the perfect companion for general pressure measurement, airflow tests, testing and balancing, speed traverses, HVAC, process control, stack testing, R & D, pressure measurements across fans, filters, etc.
