The working principle is based on that the pressure generated by the liquid column in the reservoir and pipeline is balanced with the initial pressure of the piston. Therefore, when measuring pressure, it can measure the pressure from zero. The BL504 is ideal for vacuum and low pressure calibration in primary metrology labs.
