Certainly the moisture in that '(mapped) area' would have a source, usually a deck fitting for instance. Be careful on the 'analysis,' as it may read non-structural (decorative) wall covering on the other side. Also, try to perform studies on a 'very dry' day. **Q: What is the accuracy of this meter, and what was it compared to or tested against?** A: The accuracy is ± 4%,. the reference relative drying value is the measured value of conventional air humidity (relative humidity 50%~70%, temperature 25 ℃)+compensation value of human body. **Q: Where is this manufactured?** A: Looks like China in the description. **Q: What is the difference between pinless sand pinless color?** A: As to what I understood, Pinless is a bit less accurate gives you moisture readings percentage based on humidity so if there is something as a metal behind it senses the coldness of metal and adds it as moisture vs pin one is dead spot on which senses the humidity as the pins go into drywall, wood etc Hope this helps ## Customer Reviews ### ⭐⭐⭐⭐⭐ Soddisfattissimo *by F***2 on 30 March 2026* Funziona perfettamente, testato con differenti materiali e la risposta è stata sempre realistica, facile da utilizzare, un display bello grande, sono molto soddisfatto dell' acquisto considerato il costo davvero esiguo.
