WORKFLOW GUIDE · HVAC TECHNICIANSHVAC Airflow and Static Pressure Tool Kit: Measure Conditions Before Blaming Charge
Plan complementary airside measurements: static or differential pressure, appropriate velocity measurements, temperature and humidity. Keep each reading tied to its location and method.

THE IDEA
Build the bag around the job, not the catalogue.
Plan complementary airside measurements: static or differential pressure, appropriate velocity measurements, temperature and humidity. Keep each reading tied to its location and method.
2. Measure pressure appropriately
Use the required locations, probes, tubing and instrument modes.
3. Measure air conditions and velocity
Choose access and method suitable for the sensor and the scope of assessment.
4. Compare and document
Compare against the installed equipment requirements and retain measurement locations.
JOB TOOL KIT
The tools that earn their place in the bag.
These are organized by the part of the job they support. “Core” means we would prioritize it before the nice-to-have upgrades.
Research-based tool selection from manufacturer documentation. We have not hands-on tested these products. How we choose tools →

Choose tools that fit the work.
01
Safety first
The first question is what lets you approach and verify the work safely, not which brand has the loudest launch campaign.
02
Reduce second trips
Tools earn a place when they remove guesswork, avoid a return to the van or help verify the repair before you leave.
03
Buy in the right order
Apprentices and working techs can see what is core, what is useful and what is an upgrade instead of buying everything at once.
Questions about this kit
Are a psychrometer and an anemometer interchangeable?
No. One measures air temperature and humidity; the other measures air velocity. Calculated volume also depends on dimensions and a sound measurement method.
Do I need every item before starting?
No. Buy the core equipment required by your employer and the work you are trained and authorized to do. Useful and upgrade tools are conditional choices, not an instruction to buy the whole shortlist.
Are these complete retail kits?
No. These are job-based buying plans. Confirm power equipment, probes, hoses, fittings and other separately required items in the exact retail packages.
Were these tools field-tested by TradeGear HQ?
No. Recommendations use documented capabilities and job-fit analysis. External customer feedback is separately attributed and are not our own test results.
