What is the most accurate type of tyre pressure gauge?

[Tunku]

Pencil type gauges, Digital gauges, or Dial gauges?
I'm asking because I've often wondered about how accurate my Halfords electronic pump is as I usually end up going with the reading on my old Dunlop pencil gauge as it is "machined" and gives me more confidence in it's accuracy.

Before I vote can you explain the difference between a digital gauge and a digital gauge please?

Bugger ! how does one change the last choice to Dial? Mods!!!!! Help! Oh hang on, got it !

The most accurate gauge is one that can be calibrated.

Seems to be fixed so I can now vote

Personally I use a digital one based on a review I read in one of the car mags a few years ago.

Where would one calibrate a gauge?

Go to a petrol station. Put 50p in the air machine and set it to 28psi. When it beeps to say the tyre is at 28psi, you can be 100% sure that the tyre is not at 28psi. If your gauge of choice reads 28psi, it's wrong.

BIKE magazine did a feature on this last month.

Best were the Draper 69924 dial gauge (£10) and the Halfords digital motorcycle gauge (£15).

+1 but I've voted for pencil because we use them for aircraft.

Thank-you miniman, helps enormously

You mean you haven't got a manometer?

I don't generally measure men...

Too true.

Does that mean you've found a garage air machine that isn't out of order?

This thread has just reminded me I am still waiting for my free one...

Same here. Digital ones that I have used give much better readings than crappy petrol garage dial ones.

Druck. Anything else is guessing

Not all pencil gauges are created equal, though.

I had a freebie one that would read about 2-3 psi out from my Sealey and my old digital Halfords (which both agreed with each other).

This.

The most likely to be right is probably going to be a decent digital one.
