Datasheet
A low pressure calibration setup is different from its high pressure counterparts. A sealed and controlled low pressure environment is influenced by many internal and external factors such as the climate condition, direct air flow, humidity control, pressure and temperature within the room caused by instruments, workers, and computers.
With excellent pressure regulation, the model BL507 low pressure deadweight tester is ideal primary standard for defining the pressure low to 2 kPa with 0.005% of reading.
FEATURES
Pressure ranges: (1.2~10) kPa, (2~100) kPa
Accuracy is 0.02%, 0.01% and 0.005% of reading
The piston is ceramic, which temperature coefficient is only 3.2x10-6m/℃
20cm2 Big piston areas can meet high precision float requirement
Modular piston and cylinder design is easy to maintenance and re-calibration.
Gas lubrication makes high sensitivity.
Built-in air purifier on a molecule filter
High quality needle valves provide optimum control and sealing
APPLICATION
Primary pressure standard in lab
Reference pressure measure on workshop
