Review on 🔎 Temtop Professional Quality Detector with Rechargeable Function by Alvaro Delic

This worked great, I work in sales in the HVAC industry and it has helped me sell a lot of IAQ products to help my customers. But once I turned it on, the readings were sky high every time, even after calibration. I don't know if I took it home, what damaged it or what, but it paid off the first time I used it. It also stopped working during the 30 day return period.
