The 2000 Series is Dwyer's classic versatile analogue micro-differential pressure gauge, offering 475 ranges and 27 options; it measures positive pressure, negative pressure (vacuum) and differential pressure of air and non-corrosive gases. The dial is 4 inches in diameter, accuracy is ±2% FS, the enclosure is rated IP67, and it uses a frictionless magnetic movement, making it suitable for local differential pressure indication in cleanrooms, plant rooms and ventilation systems.
| Parameter Name | Technical Specifications |
|---|---|

Positive and negative pressure monitoring in cleanrooms and equipment rooms
Install 2000 Series differential pressure gauges on cleanroom and plant room walls for local indication of indoor/outdoor differential pressure; manually adjust the supply/exhaust air ratio when limits are exceeded.
Ventilation filter pressure drop monitoring
Take pressure upstream and downstream of the filter and use the differential pressure gauge reading to assess dust accumulation on the filter screen as a basis for filter replacement.
