Reliable and Easy to Read
Dependable differential pressure gauge. The dial is clear and easy to read, and installation was straightforward. It has performed consistently and holds calibration well. Good value for the application.

No response to RMA request
Dwyer Omega your customer service is completely unresponsive. I requested an RMA on december 12th. You responded with an automated ticket 03190884 and I still have no response. This is completely unacceptable.
