- 1Slime
liquid inside the gauge interfered with performance, way off target at 45 and 44
- 2Vondoir
way off again, 25 and 34
- 3Campbell Hausfeld
seemed unaffected by the cold, still off by about the same amount, 38.5 and 37.5

missed target by a bit more than before, 38 and 39
- 5Accu-Gage
off by about the same amount as before at 41 for each gauge, with the second gauge losing pressure quickly
- 6JACO ElitePro
seemed unaffected by the cold at 40 and 39 (transcript is ambiguous whether this cold-test mention is the ElitePro dial or the separate JACO Digital gauge; assigned here by sequence position, immediately after Accu-Gage and before Joe's Racing, matching this product's position in the earlier test phases)
- 7Joe's Racing
small effect from the cold, 38.5 and 39
- 8Milton Dial (tread depth gauge)
seemed unaffected, both still at 42
- 9Longacre
the cold actually helped accuracy, both gauges described as close to perfect

cold caused a small pressure reading increase, 40.1 and 40.8

first gauge about the same at 38.9; second gauge stopped functioning properly
- 13TireTek
still very close to perfect, 40.2 and 40.5

still very close to perfect, 40 and 40.1, 'very impressive'; in the final cold-test recap, 'only one of the gauges missed the target by 0.1 PSI'
- 15SKS Germany
cold caused a small drop, 39.7 for both gauges
- 16Merlin
still very close to target, 40.1 and 40.4
- 17Pittsburgh
repaired with tape after the heat-test failure so testing could continue; 38 on the first gauge, 45 on the second
- 18UNCO Pencil
not too bothered by the cold, 40 and 39
- 19AstroAI Pencil
both gauges very close to the 40 PSI target; in a later recap sentence, 'the cold Astro AI improved accuracy and hit the 40 PSI target both times'
- 20DeWalt Pencil
first gauge hit 40 exactly; the second gauge malfunctioned dramatically in the cold, described jokingly as the pencil stick 'just about hit cousin Eddie in the forehead' (implying the measurement stick shot out forcefully rather than giving a clean reading)
- 21CZC Auto Pencil
measuring a little low, 39 for each gauge
- 22Milton Pencil
close to accurate while under pressure on the valve, but the measurement stick was observed retracting once the gauge was removed from the valve, undermining the reading
- 23Milton Dual Head Pencil
close to perfect, around 40 and 40.5

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.”
