hey,
what is the difference between power meter and gauss meter?
does gauss meter has any frequency limit?

Please suggest some good power meter for purchase.


thanx

Power meter, err, two types? If you ask an electronic engineer what is a powewr meter, he will say its a meter with a selection of load impedances (audio) or a fixed impedance (50 or 75 ohms) for RF. You connect it to your power source and it reads the power. If you pose this question to a power engineer, he will say its a meter that monitors the voltage and current going to some circuit and is calibrated in watts and/or VA.
A gauss meter measures magnetic flux. As the meter has to rely on some sort of transducer to turn the flux into a voltage, it must have a frequency range over which its accurate and an extended range where it would indicate, rather then measure.
