How it was tested

  • low-pressure accuracy test (target about 16 PSI), two physical units per brand
  • 40 PSI accuracy test, two units per brand
  • 60 PSI accuracy test, two units per brand, followed by a 5-minute pressure-hold leak check
  • valve-stem seal quality rating (1 = sealed easily, 2 = sealed well but required more force); no specific per-brand ratings were narrated beyond the general summary
  • hot-soak test (gauges left in a vehicle out of direct sun, reaching about 125F), retested at 40 PSI
  • cold-soak test (freezer at about -20C / -4F for roughly 12 hours), retested at 40 PSI
  • overall accuracy ranking by total summed pressure error across 10 readings per brand

The Jaco digital gauge did a fantastic job and came on top at 0.9 PSI.
