Immittance meter E7-21 (E721, E-7-21, E 7 21, E7 21)
Immittance meter E7-21 is designed for quality control of ERE in the input and output control and maintenance, monitoring and control of technological processes.
Parameters measured: inductance (Ls, Lp), capacitance (Cs, CP), resistance (Rs, Rp), conductance (Gp), the loss factor (D), quality factor (Q).
Immittance meter E7-21 - an inexpensive instrument accuracy class of 0.15% with greater functionality.
Measurement objects: capacitors, inductors, transformers, resistors, relays, switches, diodes, cables, input resistance and capacitance oscilloscopes, voltmeters, and other devices.
With appropriate sensors can measure various physical quantities.
