Product Description

Vacuum Deadweight Tester, (-0.1～0.25) MPa, 0.01%RD, Dry Air media, Tungsten Carbide PCU, 304SS mass set, metric connector with adapters

 

MODEL BL506 VACUUM PRESSURE DEADWEIGHT TESTER

 

 

With high precision accuracy, the BL506 vacuum pressure deadweight tester have dual vacuum and pressure modes. Pressure and vacuum application can be operated by hand pump or external gas supply. To guarantee an excellent metrology-logic characteristics, all pistons and cylinders are made of extreme hardness tungsten carbide, 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%, 0.05% accuracy
• Accuracy of low limit range keeps same as upper limit range. (Traditional deadweight tester is only 10% of maximum range).
• Pressure mode and vacuum mode can be switchable by PV selector
• 99.99% vacuum with electric pump
• The piston and cylinder is tungsten carbide, which provides stability, durability, and low thermal coefficients and distortion.
• External supply port for connection to the gas supply source or electric vacuum pump
• Assembled two-stages air purifier on a molecule filter level
• High quality needle valves provide optimum control and sealing
• Build-in liquid gas separator

APPLICATION

• Primary vacuum standard in lab
• Reference vacuum measure on workshop
