Dwyer 2000-10CM : Magnehelic Differential Pressure Gage, Range 0-10 cm, 4" (101.6 mm) Diameter Dial Face, +/-2% Accuracy
The Series 2000 Magnehelic Differential Pressure Gauge is the industry’s most trusted and widely used low-pressure gauge, offering high accuracy, durability, and ease of installation. This patented differential pressure gauge is designed to measure air and non-combustible gases, ensuring precision in HVAC systems, clean rooms, hospital isolation rooms, and industrial applications.
Key Benefits & Features
- Precision Measurement: Frictionless Magnehelic® movement ensures highly accurate readings for positive, negative, or differential pressure
- Durability & Longevity: Shock, vibration, and overpressure-resistant with a 5-year warranty for long service life.
- Installation Flexibility: IP67-rated weatherproof housing with diecast aluminum construction, ideal for harsh environments.
- Low Maintenance: No external power required for operation, reducing system costs and complexity.
- Wide Application Range: Suitable for monitoring air filters, ducts, clean rooms, hospitals, dust collectors, fan pressure, fume exhaust systems, and more.
- Easy-to-Read Dial: The 4" dial face with a clear acrylic cover provides undistorted viewing, even from a distance.
Applications of the Series 2000 Magnehelic Gauge
- Filter Monitoring in HVAC Systems: Quickly detects pressure drops across filters, signaling when maintenance or replacement is needed.
- Industrial Dust Collectors: Monitors pressure differentials to determine when filter cleaning or replacement is necessary, preventing system failures.
- Hospital Isolation Rooms: Maintains proper negative pressure to prevent pathogen spread in medical facilities.
- Clean Rooms & Laboratory Environments: Ensures required positive pressure conditions for contamination control.
- Duct & Room Pressure Monitoring: Measures building pressurization and airflow to maintain energy efficiency and regulatory compliance.
- Blower & Fan Performance: Detects inefficiencies in blower and fan systems, allowing proactive maintenance.
