Decent price but that's it
Instructions are vague, literally a business card size, website doesn't let you know that a power cord doesn't come with this and you need to make your own from something off Amazon. Definitively not plug and play.

Great Products
When I first began my journey in the HVAC trade years ago, Dwyer temperature and pressure gauges were some of the first instruments I learned to work on. They were often already installed on the equipment I serviced, and over time I noticed something: whether I was checking pressure or temperature, it was almost always a Dwyer device. I rarely came across instruments from other manufacturers, and that consistency says a lot. Dwyer products are reliable, accurate, and straightforward to work with — qualities that make a real difference out in the field.
