Hydraulic Deadweight Gauge, 50-5000 psi
$4,763.00
* Pressure tested @ 10,000 psi
All other types of deadweight instruments have the piston & cylinder installed in a body. If this body is filled with a synthetic fluid, the fluid will remain until it has leaked between the piston & cylinder. Because normal leakage approximates 0/004 milliliter per minute, the fluid should last indefinitely. When using the various testers, water can be put in the reservoir and pumped to the pressure system. If contact with the inert fluid is not objectionable, it can be used as oil normally would be in the instrument.
