HERE IS A DWYER GAUGE TO MEASURE INCHES OF WATER. I DON'T KNOW MUCH ABOUT THIS. IT WORKED UNTIL IT WAS TAKEN OUT OF THE INSTRUMENT PANEL TO UPDATE THE EQUIPMENT.
Antique Weston Panel Meter 1521. A local repair shop closed and I bought about 300 various gauges from his inventory. Untested, but this gauge looks to be in good condition.
Here we have some sort of gauge that is used to measure decibels. It appears to have been removed from something else. PLEASE NOTE: The backing paper that has the graduations on it is peeling up inside the meter behind the glass.
