  • Constant-pressure indicating system assures uniform test pressure eliminating false readings due to differences between operators.
  • Supplied in a foam-fitted carrying case.
  • Operation is as easy as pressing the spring-loaded knurled aluminum shell down to the red line.
  • Memory Pointer is included to capture peak measurement.
