This basic, easy-to-use meter measures the amount of dirty electricity (a.k.a. electrical noise, line noise, EMI) present on the wiring in buildings. Find out how much of this electrical pollution is on your wiring at home, work etc. See the difference Greenwave filters make in reducing it.

Compatible with 50/60-Hz electrical circuits with voltage anywhere between 100V and 240V. Will come with a plug suitable for the electrical outlets in your environment.

We strongly recommend this meter for guiding the installation of dirty electricity filters. It can help you determine the best number of filters to install in each room and where to place the filters for optimal results. It can also help with troubleshooting problems that occasionally arise during installation, such as resonance.
