Accu-Gage Dial Gauges
Made by G. H. Meiser & Co, this is the gauge I'm currently using.

Under the name Accu-Gauge, Meiser makes a wide variety of tire pressure gauges including dial, digital and pencil types. The dial gauges are available in a number of styles as can be seen from a perusal of their website. The one I purchased is the RS60XA; it reads to 60 PSI, has a swivel angle chuck, a pressure hold/bleed valve and a rubber gauge guard. The swivel angle chuck makes it particularly easy to apply to the tire valve regardless of its position with respect to the ground. I don't remember where I originally purchased my gauge (mail order) but it's available from the following vendor:

The current cost is:
Gauge: US $11.50
Rubber guard: $3.00
S&H: 4.95
Total: $19.45
The gauge has a steel case with a polished brass bezel and a 2" dial. Dual range scales with PSI and kPa or kg/cm squared are also available. According to the manufacturer, their dial gauges "have a full geared, solid brass precision movement with bronze Bourdon tube. Unlike piston-plunger-type gauges, the Bourdon tube movement is not affected by changes in temperature, humidity or altitude."
For those of you who might be a little rusty on the operating principal, a Bourdon tube is a C-shaped, curved or twisted tube that is open at one end and sealed at the other. The open end of the tube is fixed in position, and the sealed end is free to move. The tube is more or less elliptical in cross-section and does not form a true circle. The tube becomes more circular when there is an increase in the volume or the internal pressure of the contained fluid. The spring action of the tube metal opposes this action and tends to coil the tube. Since the open end of the Bourdon tube is rigidly fastened, the sealed end moves as the pressure of the contained fluid changes. The free end of the tube is connected to the indicating mechanism by a linkage assembly. When pressure enters the Bourdon tube, the tube movement is translated to an indicating pointer through the linkage. In the case of the Accu-Gage, a precision brass gear-driven linkage is employed.
Happy Motoring!
