AHM3 Network analyzer

Dimensions: 96 x 96
Description: The network analyzer AHM3 is designed to be used for the measurement and calculation of electrical variables, such as voltage, current, frequency, power, power factor, energy, harminic components, etc. in low, medium and high voltage power distribution.

The network analyzer AHM3 is captable of single-phase, two-phase, or three-phase measurement and can be used in two-wire, three-wire, four-wire, TN, TT and IT systems. There are four interfaces on the meter for modules which are used to extend functions.
