Single phase wattmeter

Series of single-phase Wattmeters with precision classes of 1%, 0.5% 0.3% and 0.04%, and a band of frequency from 40Hz from 400Hz and from DC to 2MHz. The Wattmeter series come in table, rack, box and board versions.

Three-phase wattmeter

Series of three-phase Wattmeters with precision classes of 1%, 0.5% 0.3% and 0.04%, and a band of frequency from 40Hz from 400Hz and from DC to 2MHz. The Wattmeter series are available in table, rack, box and Aron three-phase versions.

Single channel resistance meter

Series of single channel ohmmeters capable of measuring motor winding resistance while the motor is running. With a sophisticated decoupling system and a direct current generator, which does not disrupt the system's operation while the direct voltage is simultaneously read on the winding, with a measurement precision of 0.3%. To carry out the measurement, the power supply voltage of the motor must be sinusoidal. Measurement with PMW power supply from the inverter is not permitted. The ohmmeter series are available in table, rack, box and board versions.

Double channel resistance meter

Series of dual channel ohmmeters capable of measuring motor winding resistance while the motor is running. With a sophisticated decoupling system and a direct current generator, which does not disrupt the system's operation while the direct voltage is simultaneously read on the winding, with a measurement precision of 0.3%. To carry out the measurement, the power supply voltage of the motor must be sinusoidal. Measurement with PMW power supply from the inverter is not permitted. The ohmmeter series are available in table, rack, box and board versions.
