Which Tyre Pressure Gauges Are Most Accurate?

you are right, all concentration is needed and always have to make slight allowance for air-loss. I've used a digital one in the past which is a bit better for this, but couldn't find the patience to deal with it's random ability to change setting from psi to Bar or Kpa etc. I nearly bought this the other day:-

 

I remember reading a bike magizine article on this subject some years ago & one of this type pressure gauge was rated the most accurate !

 

Just had one of those eBay ones delivered and it's 4psi out.

 

interesting.. you sent it back?

 

Yes, they have offered a refund no problems so can't fault the seller. Just a good job I had other gauges to check it against.

 

Number 1 is the same item as No 4 in that review with different branding

 

Were the other four calibrated gauges ?

Brilliant. Thanks for the link. It looks like the one i’m after is the model RM/4S-W-G-A

 

I compared it to my other 2, it was 4 PSI low. I had previously compared my others at a TD as my old tried and tested was not agreeing with the new one so I sat on the floor with several from around the pit to get an average.

 

My point really is just make sure to check a new one against some mates ones and then do it at reasonable intervals.

Or don't, I don't mind what others do.

 

this is what I use and it’s been faultless for years despite having a hard life

 

Just remember folks - a digital readout only makes it easier to read, not more accurate/repeatable. All that display is going to show is what the sensor and it's associated electronics (both easily complete shite) are sending it.

 

+1 for Venhill

 

KTM's gauge is quite famous around my area.
