KC25-35"WC 20oz Low Pressure Gauge 35" WC 20 Oz

After fifty years of reading natural gas pressure in ounces for our natural gas engines used in production the replacement gages the gas company now provides are read in water volume.Searching the web we came across these listed on Amazon which reads in both scales and seem to be high quality.

I have this nanometer permanently installed on my homes LP system to check for leaks and regulator performance regularly.

Great gauge
