Stop in for a cup of coffee

No I am just looking to see what is available. If it is a click type it is prob 20-200. Never saw a different one when I used to calibrate them.

Yeah, it's gonna be hard to find one that low, and then it may not be accurate.


When we were in college, our prof told us that the gauge is most efficient in the center of it's range of travel.

This means that it is less accurate in the first and last 1/4" of travel, and it's most accurate at 50% +/- 25% of travel or from 1/4 reading to 3/4 reading is the most accurate. The bottom and top of the scale are less accurate....

You need to pick your gauges where they will be "operating" in the mid range at "steady state" so that you are getting accurate readings...
