Dead weight tester can be used as reference pressure equipment and high standard pressure instrument. It is the important measuring instruments of establishing pressure standard for measurement institutes. It is applied to values transferring and testing pressure gauge, precision pressure and pressure transmitters.

Feature

Ø  The piston rod and cylinder uses tungsten carbide material with high strength, high hardness and low coefficient of thermal expansion;

Ø  increasing the wear resistance of piston, reducing linear expansion and deformation coefficient of the piston rod and cylinder.

Ø  Using quick connectors, no leakage

Ø  Pistons that more than 25MPa uses cradle structure; with low gravity and excellent stability

Ø  Pistons’working position is numeric displaying; eye-catching and more accurate

Ø  Consistent with nominal range and measuring rang
