Concrete Air Meter Gauge

The concrete air meter gauge reads the air content of concrete during an air content test.  The stainless-steel gauge has an accuracy of ±1% at full scale and a rubber gasket seals its glass lens to protect from moisture and dust.  It also has a 1/4″ diameter thread on its bottom that screws into the top of the 45-degree elbow. It is compatible with most every meter.
