The compact instrument is designed for the measurement of the electric resistance to the direct current of various units, switchboard panels, small electric substations, electric apparatus and others, including the breaker contacts, bolted and soldered joints of the electric system circuits under the conditions of the noise of electrical field with the potential stress of up to 20 kV/m.

Microhmmeter TS-2 is designed for the measurement of the small values of the electric resistance under the laboratory environment. The modern instrument has the broad measurement range, small size. It is reliable and easy-to-operate.

Microhmmeter TS-3 is designed for the measurement of the electric power systems interconnect circuit transient electrical resistance: aerial, oil-immersed and other contacts, disconnect switches, bolted and soldered joints under the conditions of the noise of electrical field with the potential stress of up to 30 kV/m (electric substations – up to 750 kV). The instrument and its superseded models (MMO-1, БС3-010 and others) have been efficiently operated by the fuel and energy complex companies in Russia, Belarus, Ukraine and Kazakhstan for somewhere about twenty years.

Microhmmeter TS-200 is designed for the measurement of the electric power systems interconnect circuit transient electrical resistance: aerial, oil-immersed and other contacts, disconnect switches, bolted and soldered joints under the conditions of the noise of electrical field with the potential stress of up to 30 kV/m (electric substations – up to 750 kV).

Ohmmeter "Vitok" is designed for the measurement of the electric resistance to the direct current of the items that have rather high inductance: power transformer windings, generators, electric motors, power cable cores (on the metal frames) and others.
