BL504 LIQUID COLUMN PRESSURE STANDARD SPECIFICATION Pressure range: -0.1MPa to 0.7MPa Accuracy: ±0.005%rd + 1Pa Piston material: Tungsten Carbide Cylinder material: Tungsten Carbide Mass material: 304 stainless steel Base material: Aluminum alloy / stainless steel Transform medium: Mineral oi Column liquid: Mercury, silicon oil Mass carrier weight: 1kg Mass quantities: 0.1kg x1pc, 0.2kg x2pc, 0.5kg x1pc, 1kg x6pcs, Gravity: Custom to local or standard 9.80665 m/s² Pressure connector: Metric Power supply: 100-240VAC Base dimension (W*D*H): 480 x 400 x 680 mm Column Height: 800 mm Weight: 26 kg for base, 6 kg for column SCOPE OF DELIVERY The BL504 liquid column pressure standard is a piston pressure vacuum gauge with a balanced liquid column. 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. FEATURES Ranges from -0.1MPa to 0.7MPa ±0.005%rd + 1Pa accuracy Motor drives the weight rotating.
