Good energy monitoring devices

The ELV Energy Master Basic energy-measuring devices is the third instrument that I possess.
My first two instruments come from the lower price segment (z. B. from discounters). The discounter gauges show the same DUT at different measurement results. Since I did not want to rely on these inaccurate values, I have decided to buy a high-quality energy monitoring devices.
Due to the many positive reviews and the exact diameter results from ELV product, I decided for the ELV Energy Master Basic energy monitoring devices. The professional version of this instrument was not relevant for me because I do not need 10 memory profiles and storage of measurement results in the unit. Apart from these two functions, the Basic and Pro version is the same.

The ELV Energy Master Basic energy monitoring devices makes a very good and high-quality impression. Operation is very simple and intuitive. (Price of kWh) configuration of tariffs was, in my opinion, easy to program. Very positive that the measurement results indicates already readings from 0.1W. Here the discounter Prodikte simply could not keep up.

The only small and night part is that of the ELV Energy Master Basic energy monitoring devices a faint beeping / hum is heard.
At first I thought that the device is defective. After consultation with the ELV Support this quiet beep / buzz is normal and due to the coils used in the device.

Conclusion:
I'd go again for the ELV Energy Master Basic energy monitoring devices and can only recommend it. ELV offers a very good instruments for the average consumer.
