Dwyer Series 2000 Magnehelic

Here’s an oldie but goody. If you’re the nostalgic type who enjoys needles bouncing back and forth, the Dwyer Magnehelic is just the tool for you. Measuring in at a whopping zero to one inch of water column, this Magnehelic will make you money any time you take it out of its box.

With its bright orange needle and decently large numbers, you’ll never question the measurement.

Before you view the measurements, the Magnehelic needs to be level to your eyes, front-to-back as well as side-to-side. It comes with two ports so you can measure different pressures across a system component.
The information it provides is worth its weight in gold.
