As an HVAC business owner and technician, I like to carry only one meter that will do everything I need to do. It is difficult to find a good one but not impossible. I was looking at what is available and found that the Uni T 219DS has everything I could ever want in a meter. My question is, and I know there's a lot of bashing Uni T, but there is also some love for certain Uni T meters. What is the groups opinion of the 219DS?
