Tire Pressure Gauge

Possibly the Worlds Finest Tire Inflation Gauge 

Our testing is complete and we could not be happier with the new PCL Accura 1 tire pressure gauge. Over the years we have tested a great many commercially available tire pressure gauges. Most were not accurate enough or did not repeat their readings accurately. Finally we decided to build our own air pressure gauges, using test quality instruments. These worked great, but were difficult to build and fragile.

The answer for our search was finally found in the PCL Air Technology, Accura 1 digital tire pressure gauge. These gauges are manufactured in Sheffield, England and in our opinion are the most accurate tire pressure gauges in the world. They both check and with the squeeze of a trigger, inflate and if needed deflate tires. We have replaced our entire stock of original gauges with these fine tools and could not be happier.
