| Combining high quality,
long life and permanence of calibration, the RBB Series offers
an unbeatable selection of models. The reliability is built
in as we use our own designed and manufactured switches combined
with high quality wire wound resistors. All units are supplied
complete with certificate of conformity and all measurements
are of course traceable to International Standards |
Special models are available for temperature
(Pt100) and insulation resistance simulation.
