Frequently Asked Questions

What is the Dwyer Magnehelic 2000-300PA pressure gauge used for?

The Dwyer Magnehelic 2000-300PA differential pressure gauge is used for HVAC system diagnostics, flow verification, and industrial process monitoring. It indicates positive, negative, or differential air and non-combustible gas pressures, making it suitable for filter monitoring, fan tracking, and cleanroom applications in Singapore facilities.

What are the specifications of the Dwyer Magnehelic 2000-300PA?

The Dwyer Magnehelic 2000-300PA has a 101.6 mm dial, 1/8" female NPT connections, and operates from -6.67 to 60 °C. It is designed for diaphragm-vertical mounting, handles air and non-combustible gases, and offers ±2% full-scale accuracy. The die-cast aluminum case is weatherproof to IP67.

Where to buy the Dwyer Magnehelic 2000-300PA in Singapore?

3G Electric supplies the Dwyer Magnehelic 2000-300PA differential pressure gauge to Singapore. We handle logistics, customs clearance, and local delivery for procurement engineers and plant maintenance teams. Contact us for pricing and lead time on this Dwyer measurement instrument.

How to install the Dwyer Magnehelic 2000-300PA pressure gauge?

Mount the Dwyer Magnehelic 2000-300PA with the diaphragm vertical for accurate readings. Use 1/8" female NPT connections for high and low pressure ports. Ensure the rubber pressure relief plug is unobstructed to allow overpressure venting. Avoid exceeding 15 psig pressure limits for standard models.
