Description
The Dwyer 2301 Differential Pressure Gauge is a reliable, analog pressure instrument designed for measuring low differential pressures in air and compatible non-corrosive gases. This model has a 0.5-0-0.5 inches water column (W.C.) range, making it ideal for monitoring airflow, duct and room pressure differences, filter status, fan or blower performance, and cleanroom pressurization in HVAC and industrial systems.
Key Features
- Differential pressure range of 0.5-0-0.5 in. W.C. for low-pressure HVAC applications
- Clear analog dial with 0.02 in. minor divisions for fine resolution
- Durable die-cast aluminum case and bezel with acrylic cover
- Weatherproof housing suitable for indoor/outdoor use (rated IP67)
- Dual 1/8″ female NPT high/low pressure taps for easy tubing connection
- Works without electrical power; simple mechanical gauge design
- Ideal for monitoring filter pressure drops, duct pressures, and airflow balance
