Potentiostat / Galvanostat / Impedance Analyzer
PalmSens4
PalmSens4, is a USB and battery powered Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The PalmSens4 has a large potential range (-5V to 5V or -10V to 10V) and current range (100 pA to 10 mA) with a high resolution and low noise. This instrument is a complete laboratory instrument but its compact and rugged design makes it also ideal for field work.

Known impedance for use in loudspeaker measurements
Impedance Box
An impedance box is necessary for measuring the impedance of a loudspeaker. Listen Inc.’s impedance box contains a 0.25Ω resistance. This value is suitable for most loudspeakers, but may be easily swapped out for a different value by the user if speakers with a particularly high or low impedance are being tested. It is available with either XLR or 1/4″ balanced connectors. Please specify type of connectors when ordering.

Impedance Meter, Audio, 200Ω, 2KΩ and 20KΩ scales
72-6948
Active device is essential for reliable installation of background music and paging systems in residences, offices buildings and public areas. Avoid costly service calls and amplifier damage by verifying actual speaker system impedance prior to operation. Unlike conventional volt/ohm meters, which measure DC resistance, this unit utilizes an internal 1KHz oscillator to measure true impedance. Accurately measure speaker lines that utilize impedance matching volume controls, switchers, transformers and passive crossovers. Because this unit accurately measures up to 20Kohm, it may also be utilized with 25V, 50V, 70V, and 100V speaker line transformers in commercial installations.

Impedance Measurement
CITS880s
Finer geometries and thinner copper can present a challenge for fabricators measuring impedance on leading edge PCBs. The CITS880s answers that challenge with the introduction of Launch Point Extrapolation (LPE). LPE extrapolates the TDR response back to a point close to the start of the transmission line effectively allowing to users more accurately to measure the instantaneous or incident impedance of the line.

High Impedance Transformers
Osborne high impedance transformers are used to step-up, step-down and isolate voltages in single phase and three phase circuits. A properly designed high impedance transformer can be used an an equivalent to an isolation transformer connected in series with an inductor. The high impedance characteristic may be employed as a current limiting feature in both the primary and secondary circuity.
