- Instruction Manual, Spare Seals,Dust Cover
- Set of Weights in Carry Box, Tool Bag
- Hydraulic Fluid (½ Liter) & Seal Kit
- Traceable Calibration Certificate
Optional Accessories :
- 1/8", 1/4", 3/8", 1/2" NPT Adaptors
- Pointer Puller, Pointer Punch
- Carrying box for tester
Operating Principle:
Fluid Pressure generated by a screw pump acts on the bottom of a vertically free floating piston. The force produced pushes the loaded free piston vertically upwards. The piston floats freely in its cylinder and the pressure in the circuit will be determined by the weights loaded on the piston divided by the effective area of the piston with corrections for value of acceleration due to gravity, air buoyancy, surface tension and datum level difference.
