Datasheet
With 0.005% of reading high accuracy, the BL506 vacuum pressure deadweight tester can precisely measure the 99.9% vacuum and 1MPa positive pressure. Pressure mode and vacuum mode can be easily switched by switch valve. To guarantee an excellent metrology logic characteristics, all pistons and cylinders are made of tungsten carbide. Because of the extreme hardness of this material, the pressure distortion (expansion) coefficient is negligible. The low friction coefficient provides minutes of turning with just a little swing of the masses.
FEATURES
0.005%, 0.01%, 0.02% accuracy.
Pressure mode and vacuum mode can be switchable by PV selector easily
LCD tough screen displays ambient pressure, temperature and humidity.
The integrated piston bracket design improves sealing and stability.
The built-in gas safety valve can protect the piston system from high flow impacts.
The intake flow control valve can control the flow more finely and accurately, avoiding damage to the piston system caused by excessive intake flow
High quality needle valves provide optimum control and sealing
APPLICATION
Primary vacuum standard in lab
Reference vacuum measure on workshop
