Teslameter-fluxmeter universal TPU-2V

Teslameter-fluxmeter universal TPU-2V.

Teslameter-fluxmeter universal TPU-2V is designed for measurement of magnetic induction of constant magnetic fields, maximal values of magnetic induction of alternating and impulse magnetic fields, flux linkage using connected to TPU-2V measurement coil. If a measurement coil with known turns count and mean turn square of cross section of coil is connected to TPU-2V, the instrument is able to measure magnetic flux through that coil and magnetic induction. If a Helmholz coil with known coil constant is connected to TPU-2V the instrument allows to carry out measurements of magnetic moment and obtain magnetization of sample that is placed into Helmholz coil
Teslameter-fluxmeter TPU-2V can be used in precise analysis of magnetic fields, generated by magnetic systems and electrical devices of different purposes. Also it can be used in measurements of magnetic parameters of materials in closed or open circuit
