Review on 📏 Dwyer 475 6 FM Digital Handheld Manometer by Bernard Her

Poor quality. The outer lining appeared to be smeared with glue around the label (which I could live with). The biggest problem is that the zero button didn't work. When activated, it read a value (as expected with normal drift), but that value was significantly far from zero, and the zero button didn't seem to do anything. Finally returned it. PS - I still have one of these, 12 years old, that still works well, so I chose this brand when I needed a different pressure range. should have listened to other reviews which indicated the quality is no longer there.
