Bruel & Kjaer's Impedance Meter System provides aerospace engineers with a user-friendly system, suitable for carrying out research and production quality control impedance measurements, up to 150 dB SPL on engine nacelle liners.
The Portable Impedance Meter system lends itself well to the measurement of acoustic properties of aircraft interiors and trim materials.
In his office, he uses a bioelectrical impedance meter
to measure skeletal muscle versus fat tissue mass, from which calculations can be made for the number of calories per day required to reduce weight in a certain period of time.
Such equipment includes a lab-quality digital RCL bridge, vector impedance meter
, network analyzer, etc.
