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, an over-pressure limit of 100% full scale, and measures pressure in mBar via a center-back process connection with 0.125-inch tubing.

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 ±1.00% accuracy supports monitoring filter status, airflow, or pressure drops.

What are the specifications of the Dwyer DM-1109?

The Dwyer DM-1109 is a DM-1000 series digital differential pressure gauge with a 5-inch dial, center-back process connection for 0.125-inch tubing, and mBar pressure units. It has ±1.00% accuracy, 100% full-scale over-pressure limit, and a NEMA 4X glass-filled plastic case.
