Accurate gauge, but with minor flaws
on August 9, 2011
I have several dial (analog bourdon tube) gauges to measure tire pressure, plus a Milton inflater with a built-in gauge. My (GM) car also has TPMS. My service dept claims the TPMS is accurate to within about 1lb. This Accutire gauge is in exact agreement with the TPMS in the car, and one of the dial gauges. The other gauge and the inflater are about 2lbs off. With dial type gauges, some interpretation is required at times depending on the divisions of the scale. The 2 dial gauges I have use 2lb divisions. So if the pointer is somewhere between 34 & 36lbs, is it 35, or 34.5? This is why I wanted a digital gauge.
Having 4 gauges all reading within 2lbs of each other is very reassuring. This digital gauge seems to be very accurate. The metal housing allows a firm grip, and should stand up to continued use. It uses commonly available CR2023 batteries which are replaceable. It does NOT have a lifetime lithium battery.
The flaws are minor, thus my 4-star rating. As other reviewers stated, the LED light is not very useful, but you can just ignore this by not pushing the flashlight button. The tire valve chuck also does take a little getting used to, as others have said. But it's not that hard, and with a few tries, you can get a reliable seal and accurate reading.
The other thing is that you must hold the gauge on the tire valve for 1 or 2 seconds for it to "lock-in." I've found that you can push the gauge on the valve and get a reading, but if you don't wait long enough it goes back to zero immediately after removing the gauge. By keeping the gauge on for a second or 2, the pressure reading is retained for about 10 seconds, making it much easier to read. The instructions that come with the gauge state this is a feature to "zero" the gauge to ensure accuracy.
