The Topcon ES-105 series of reflectorless technical total tacheometers with five-second angular accuracy and an expanded set of functionality introduces new standards in the production of geodetic surveys. From the first measurements you can appreciate all the advantages of this tacheometer.

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 The instrument and its superseded models (MMO-1, БС3-010 and others) have been efficiently operated by the fuel and energy complex companies in Russia, Belarus, Ukraine and Kazakhstan for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.

Ohmmeter OA 3201 provides the measurement of the electrical resistance as well as the control of the measured value variance from the set value.

Digital kilovoltmeter SKV-10-ST is designed for the measurement of the direct current voltage, effective and crest values of the alternating current voltage. The instrument can be used for the adjustment of the measuring voltage transformers, control and measurement of the signals when producing and metering the electricity. The kilovoltmeter measuring unit power supply is carried out with the help of the battery: - Voltage – 6 V; - Capacity – 1.5 A/h.
