IMPORTANT! There are many EMF meters available on the market. Making a decision can be confusing and frustrating. Everyone seems to be an EMF expert and they want to sell you meters through affiliate links when they have not even used or tested the meters they are selling! After many years of professional EMF consulting and experience with various meters, I am providing ONLY the EMF meters I feel to be wise and excellent choices for measuring wireless (microwave) radiation and low level electric and magnetic fields. Here is my opinion and suggestion. Do not look for a "trifield" meter, which is a single meter which can measure microwave, electric and magnetic fields. These types of meters are usually lacking quality and correct calibration. I highly suggest purchasing a dedicated microwave meter as your first priority, and as a second priority, an additional, dedicated meter for measuring electric and magnetic fields. This suggestion comes from years of purchasing, using and testing many different meters. I feel strongly the meters being being offered here are the best choices on the market!
