Calibrator of precision accuracy.
It is widely demanded by centres of standardisation and metrology of Russia, metrological laboratories, scientific and production companies, scientific and production associations, as well as JSC "Russian Railways".
General information about the device: Multifunctional calibrator H4-17 was developed to replace the well-known model H4-7. It retains the leading position in the line of calibrators of high and highest accuracy.
The calibrators have a standard set of functions, providing the implementation of calibrator modes of DC and AC voltage, current and decade range of resistance from 1 to 108 Ohm. The basic unit has a range of operating voltages and currents up to 200 V and 2 A respectively, which is extended up to 1000 V and 20 A by the amplification unit H4-17 BU.
