Details

Cherne’s Aluminum Fin Style Deflection Gauges are designed to be field verified by inspectors without the use of a proving ring. Simply place two fins end-to-end as pictured below (1) and measure the width. Add one inch to the mandrel (2) and you have the outside dimension of the gauge. Using this method simplifies the inspector's job of verifying sizes on deflection gauges.

  • Field-verifiable without a proving ring
  • Assembles without tools
  • All sizes fit through standard 24 in. manhole
  • Fins for 4 in.-15 in. gauges have skid size equal to th nominal pipe size-gauge will meet regional codes and will not tip in the line
  • Nine-fin design ensures testing accuracy
  • Open design allows gravel and debris pass-through
