For the uninitiated, a good device that in my estimation also provides reliable values. The handling is very simple and self-explanatory. Test measurements on different substrates in the House have shown values that are likely to be correct. eg internal plasterboard wall 0%. Plastered basement wall in unheated space 12%. Wood paneling on a covered balcony 16%. Angefeuteter brick in the basement after 10 minutes waiting time 25%. The device is well worth the money. I would recommend it. Because price and performance are 5 star. Who wants more must halt a contractor.
