Beyond common ranges, the Dwyer Magnehelic® 2000 Series offers extremely low-range options tailored for applications demanding maximum sensitivity. The 2000-500PA (500 Pa range) and 2000-60PA (60 Pa range) models are perfect for monitoring minute differential pressure fluctuations in specialized HVAC systems.
1. Comparing the 2000-500PA and 2000-60PA
Both models utilize Dwyer's trusted Magnehelic® technology, operating without power for long-term stability. The 2000-500PA is ideal for medium-low differential pressure applications, while the ultra-low 2000-60PA is specifically engineered for high-sensitivity requirements such as strict cleanrooms or pressure isolation wards.

3. Installation and Operation Guide
-
Select the model matching the actual DP range: 2000-60PA for ultra-low applications, and 2000-500PA for medium-low ranges.
-
Mount the gauge with the diaphragm in a vertical position. This is especially crucial for the sensitive 2000-60PA, as position variations strongly affect accuracy.
-
Calibrate the zero point using the zero-adjustment screw prior to operation.
-
For the 2000-60PA, avoid installations near doors or in direct turbulent airflow to prevent needle fluctuation.
-
Perform periodic zero re-calibrations (every 6-12 months) to maintain strict accuracy in cleanroom/isolation applications.
⚠️ Important Note: The highly sensitive 2000-60PA is perfect for high-level cleanrooms or negative/positive pressure isolation rooms in hospitals, where detecting minute pressure drops is essential for infection control.
4. Common Applications
-
2000-500PA: Monitoring filter resistance and industrial ventilation duct pressure.
-
2000-60PA: DP control for ISO 5-7 cleanrooms and hospital isolation wards.
-
Pharmaceutical and electronics labs demanding stringent airflow control.
