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

Measures Velocity, Diff / Gage Pressure, and Flow

FlowKinetics FKS 1DP-PBM meter

The FKS 1DP-PBM is a meter designed for air pressure measurement, air velocity measurement, and air flow measurement 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 testing and balancing, velocity traverses, HVAC, process control, stack testing, R & D, pressure measurements across fans, filters, etc.
