Hydraulic weight balance

Deadweight testers are used as the basic primary standard and its principle is accepted all over the world for the most accurate pressure measurements.


The DOS001 Oil Dead Weight Tester is accurate to within 0.01% of reading. The weight column and pump are mounted on a stainless steel base plate.

A frame triangle is used to make a stable and solid base for the weight column and can be leveled with a spirit level. The weight carrier is of the suspended type and therefore insensitive to any negative influences such as the friction of a support piston.

An EA RVA certificate from an accredited third party is standard. The certificate shows the effective area and weight of each mass.
