Product Description

The DWYER DM-1000 is a digital differential pressure gauge for air and compatible gases, featuring a glass-filled plastic case with a NEMA 4X enclosure rating. It offers ±1.00% accuracy, a 100% full-scale over-pressure limit, and a center-back process connection for 0.125 in tubing, measuring pressure in Pa.

Frequently Asked Questions

What is the DWYER DM-1000 digital differential pressure gauge used for?

The DWYER DM-1000 measures differential pressure of air and compatible gases in HVAC, cleanroom, and industrial process applications. Its NEMA 4X glass-filled plastic case suits washdown or corrosive environments, and the center-back connection accepts 0.125 in tubing for easy panel mounting.

What are the specifications of the DWYER DM-1112?

The DWYER DM-1112 is a DM-1000 series digital differential pressure gauge with a 5 in dial, ±1.00% accuracy, and 100% full-scale over-pressure limit. It measures in Pa, has a glass-filled plastic NEMA 4X case, and a center-back process connection for 0.125 in tubing.
