2830/2831

Haefely's 2830/2831 is the result of extensive research and years of experience testing
dielectric properties of liquid and solid insulating materials. It incorporates a fast and highly
advanced procedure to measure capacitance, tangent delta (dissipation/power factor),
resistivity, and relative permittivity of liquid or solid insulating materials.
A simple one-time-connection system together with resistivity measurement according to
pre-selected standards drastically reduces measuring time.  The system consists of 2830,
the measuring bridge and control unit, and 2831, the extension unit. This system is a
complete replacement of the Tettex 2821 and 2822. The 2830 contains the controller and
the measurement part of the system. The 2831 extension unit contains a standard capacitor,
2.5 kV AC & DC power supplies and a temperature control unit.
