Dial type vs. Pen type tire gauge

**andrewnathaniel** · November 22nd, 2014 04:11 PM

Up lang mga bro.

Nakabili ako sa Handyman, Dial type, Elevo ang brand. Hindi accurate. Minus 8 psi sya, nagpapalit kasi ako ng tire then pinainflate ko ng 30psi lahat ng gulong. Ang reading lang sa nabili ko eh 22 psi. So naisip ko agad na etong binili ko ang hindi accurate kasi yung iba din naming sasakyan eh 30psi din, ang reading lang din eh 22 psi.

Wala ba talagang tire pressure gauge ang mabibiling accurate? Yung pen type ko, minus 5 naman. Kung digital kaya, accurate? TIA

I use Stanley pen type and the Elevo dial type. I think they're both accurate

Or every once in a while, get your tire pressure checked at those automatic air stations at Caltex or Total. That'll settle your doubts

My old pen type that I got as a promo item from Shell ages ago (15 years or so) & my new dial type from Ace. It is all metal and the intake port is straight. Difference is around 1 psi.

Di ko binasa lahat ng pages, pero siguro enough to note that both do well and that what's more important is that it's calibrated.

But how do we calibrate? I have a buffalo brand pen type gauge and it is -4 psi off both the gas station's built in gauge and a digital one that the gas boy used. So are theirs' calibrated accurately or just coincidentally had the same reading? Anyway, on my 30 psi requirement, i put 32 psi with my guage just so I have a 7% buffer for under inflation and if the others are correct, then I have 36 psi which is being 20% over inflated.

In my case, same ang reading ng Digital Tire Gauge ko (which I posted in previous page) sa binili kong Automatic Digital Tire Inflator.

With the Automatic Digital Tire Inflator, I just preset my desired PSI and it will fill the tire to the target PSI and automatically stop when done. It has backlit LCD display and shows the tire pressure in real time.
