Instrumentation

To take measurements and obtain the readings we are talking about in this article, you’ll need a static pressure test kit (ncilink.com/SPTestKit). HVAC Industry technicians typically use a gauge like the manometer (ncilink.com/EBT730) or Magnehelic (ncilink.com/magnehelic) to measure static pressures.

The manometer is great for new-age techs because this instrument is quick, easy to use, and can communicate to smartphones via apps.

But if you’re old school and prefer a tried-and-true instrument, then pick up a Magnehelic gauge. Magnehelics also measure static pressure but are better from a sales point-of-view because of their visual display. This feature helps you better explain static pressure issues to your customer.

Don’t forget some of the accessories you’ll also need, including tubing and static pressure tips. The tubing connects the static pressure tip to the manometer. You’ll also need a way to install test ports, so that means having a drill bit with a protective sheath or a step bit.

Use the sheath with standard drills for safety. It stops the bit from penetrating too deeply into the ductwork and damaging internal components.

At the NCI Virtual Summit (gotosummit.com), we will go into more detail on how you get your technical team to understand and properly perform their test measurements. We’ll also discuss other measurements you can take to find and solve even more issues with the systems you run into.
