Frequently Asked Questions

What is the Dwyer Magnehelic gauge 2000-125PA used for?

The Dwyer Magnehelic gauge 2000-125PA measures low differential air pressure from 0 to 125 PA. It is commonly used in HVAC systems to monitor filter pressure drop, in cleanroom environments for room pressurization verification, and for checking fan or blower performance in industrial facilities.

What are the specifications of the Dwyer Magnehelic gauge 2000-125PA?

The Dwyer Magnehelic gauge 2000-125PA has a 4-inch dial with ±1% full-scale accuracy, a 0-125 PA pressure range, and 1/8" female NPT connections. It operates from -6.67 to 60°C and is suitable for air and non-combustible gases. The die-cast aluminum case is weatherproof to IP67.

Where to buy the Dwyer Magnehelic gauge 2000-125PA in Singapore?

3G Electric supplies the Dwyer Magnehelic gauge 2000-125PA to customers in Singapore. We handle logistics, customs clearance, and delivery to your facility. Contact our team for a quotation and lead time on this Dwyer differential pressure gauge.

How to install the Dwyer Magnehelic gauge 2000-125PA?

Mount the Dwyer Magnehelic gauge 2000-125PA on a flat surface using the four mounting holes, or panel-mount with the optional bezel. Connect the high-pressure line to the 1/8" NPT high port and the low-pressure line to the low port. Ensure the rubber relief plug is unobstructed for overpressure protection.
