| Product | Construction | LowPressureTest(target ~16 PSI) | MidPressureTest(target 40 PSI) | HighPressureTest(target 60 PSI) | HotTest(125F, target 40 PSI) | ColdTest(-4F, target 40 PSI) | LowPressureTest(target ~16.1 PSI) |
|---|---|---|---|---|---|---|---|
| 1Slime$10 | dial gauge, liquid-filled dial, 0-60 PSI range, 202.44g, made in China, claims to be 'easily the best dial pressure gauge' | 17, 17 (both 1 PSI over) | 40.7, 40.5; did not lose pressure in the 5-minute leak-hold test at 60 PSI | 60, just below target on the second gauge | heat hurt accuracy by about 2 PSI per gauge, now 37 and 38 | liquid inside the gauge interfered with performance, way off target at 45 and 44 | not tested |
| 2Vondoir$13 | dial gauge, 0-100 PSI range, 234.39g, made in China, claims accuracy within +/-1% | 9 (way off), 14 | 34, 38; did not lose pressure in the 5-minute leak-hold test at 60 PSI | 58, 54 | heat did not help or hurt, still way off at 34 and 38 | way off again, 25 and 34 | not tested |
| 3Campbell Hausfeld$14 | dial gauge, 0-60 PSI range, 119.95g, made in China | 13.7, 13 (off by about 3 PSI under) | 38, 37.6; did not lose pressure in the 5-minute leak-hold test at 60 PSI | 57.5, 59.5 | heat helped slightly, about 1 PSI closer to target on each gauge | seemed unaffected by the cold, still off by about the same amount, 38.5 and 37.5 | not tested |
| 4Rhino USA dial$16 | dial gauge, 0-60 PSI range, ANSI certified, glow dial, 179.04g, made in China | not tested | 39.7, 38.5; grouped among gauges that 'did not lose pressure' in the 5-minute leak-hold test at 60 PSI | 59.5, 57.5 | very little impact, 39 and 40.5 | missed target by a bit more than before, 38 and 39 | very close to 16.1, 15.5 on the second gauge |
| 5Accu-Gage$16 | dial gauge, 0-100 PSI range, 166.11g, made in China, claims to be unaffected by temperature, altitude, or humidity unlike digital gauges | 18 (a bit high), 17.5 (closer, but bleeding off pressure) | 41, 41; one of the two units lost pressure during the 5-minute leak-hold test at 60 PSI (transcript does not specify which of the two) | 60, 59 | heat hurt accuracy by about 0.5 PSI per gauge | off by about the same amount as before at 41 for each gauge, with the second gauge losing pressure quickly | not tested |
| 6JACO ElitePro$23 | dial gauge, 0-100 PSI range, 235.86g, made in China, ANSI-standard certified accuracy of +/-1.5% | 17.1 (holding steady), 16.5 (bleeding off pressure quickly) | 41, right on target (~40) on the second gauge; grouped among gauges whose units 'lost pressure' during the 5-minute leak-hold test at 60 PSI (transcript does not specify which unit) | 58, 59 | no measurable impact, pressure stayed the same | 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) | not tested |
| 7Joe's Racing$29 | dial gauge, glow-in-the-dark face, 0-60 PSI range, made in USA, 299.17g, does not remember tire pressure between uses | 15.2, 16.5 | 39.5, 39 | 59, 58.5 | heat helped accuracy slightly, now 39.5 and 40 | small effect from the cold, 38.5 and 39 | not tested |
| 8Milton Dial (tread depth gauge)$29 | dial gauge with a built-in tread depth gauge, 0-130 PSI range, made in Taiwan, 202.31g | very close to 16, 18 (2 PSI over) | 42, 42 (both too high); grouped among gauges that 'did not lose pressure' in the 5-minute leak-hold test at 60 PSI | 61, 61 (both too high) | seemed unaffected, still 42 for both gauges | seemed unaffected, both still at 42 | not tested |
| 9Longacre$37 | dial gauge, glow-in-the-dark face, 0-60 PSI range, made in USA, 290.63g | 15.4, right on target (16) on the second gauge | 1 PSI too high (~41), right on target (~40) on the second gauge | 61, right on target (60) | very little impact, 40.6 and 40.7 | the cold actually helped accuracy, both gauges described as close to perfect | not tested |

| 11ETENWOLF$10 | digital gauge, 3-200 PSI range, AAA batteries, work light, made in China, 102.81g, claims accuracy to +/-0.5% | 16, 16 (both exactly on target); narrator's top pick for low-pressure accuracy: 'the very affordable Eton Wolf is the most accurate at low pressure with both gauges hitting the target' | 40, 40.1, described as 'not bad for a $10 gauge'; total combined error across both gauges only 0.1 PSI | 60.1, 60.3, 'not bad for $10' | heat impacted it, but still close to target, 40.5 and 40.4 | was close to perfect before, now slightly off at 39.2 and 38.8 | not tested |
| 12Rhino USA Digital$11 | digital gauge, powered by a 3V lithium coin cell, operating range 23-122F, lighted nozzle and LCD backlight, made in China, 55.84g | 14.8, way off at 7.1 on the second gauge; narrator notes 'I made several attempts and the results were the same' | 38.9, way off at 30.6 on the second gauge | 51 (struggling), 58.8 | heat hurt accuracy noticeably, 38.5 and 27.8, described as about 1.5 PSI less accurate than before | first gauge about the same at 38.9; second gauge stopped functioning properly | not tested |

| 16Merlin$30 | digital gauge designed to attach to an air hose (unlike the other gauges tested), 5-150 PSI range, uses two AAA batteries, sold at Harbor Freight, made in China, 424.9g | not tested | 40.3, 40.2 | 60.2, 60.4 | performed very well, pressures remained the same at 40.3 and 40.2 | still very close to target, 40.1 and 40.4 | 16.1, 16 (on target); narrator's per-pressure-point runner-up at low pressure: 'Merlin finished in second at 0.1 PSI off target' |
| 17Pittsburgh$1.39 | pencil gauge, up to 75 PSI, sold at Harbor Freight, made in China, 15.67g; least expensive gauge in the entire video | 21.5 (way off), 17 | 39, way off at 45 on the second gauge | 63, 58 | did NOT survive the heat test (failed/broken) | repaired with tape after the heat-test failure so testing could continue; 38 on the first gauge, 45 on the second | not tested |
| 18UNCO Pencil$4 for two ($2 each) | pencil gauge, 10-75 PSI range, made in China, 23.16g | 17, 17 | described as 'not too far off the target' at 41 for both gauges | 60, 60.5 | now about 0.5 PSI closer to target on each gauge, 40.5 for both | not too bothered by the cold, 40 and 39 | not tested |

| 20DeWalt Pencil$5 | pencil gauge, 0-60 PSI range, made in China, about 23g | 17, 16.8 | 41, 40.5 | around 60.5, 59.5 | heat threw it off by about 0.5 PSI on average, 41 and 39 | 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) | not tested |
| 21CZC Auto Pencil$18 for two ($9 each) | pencil gauge, ABS rectangle white scale plate, dual head chuck, 10-150 PSI range, made in China, 149.25g | 16.5 ('a little bit challenging for the eyes'), 16 | both gauges appeared close to 40, hard to read with precision | 59.5, 60 | remained unchanged, close to 40 for each gauge | measuring a little low, 39 for each gauge | not tested |

| 23Milton Dual Head Pencil$17 | pencil gauge, dual head design, 10-160 PSI range, made in USA, 225.26g | 16, 15.5 | 40.5, 40.5 | 60.5, 60.5 | narrator notes it 'really liked the heat,' both gauges landed right on target at 40 | close to perfect, around 40 and 40.5 | not tested |
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.”
