AHM1 Network analyzer

Categories:
Description: The network analyzer AHM1 is designed to be used for the measurement and calculation of electrical variables such as voltage, current, frequency, power, power factor, energy, harmonic components, etc. Memory of 8 MB incorporated.
  • B model: Is a basic version of the AHM1,  that does not include digital inputs and contact outputs. It does not have RS 485 port either.
  • BC model: In contrast to the basic model, it has RS 485 communication.
