Budenberg Gauge Co. Ltd are a leading manufacturer of primary pressure calibration systems including Hydraulic Deadweight Testers, Pneumatic Deadweight Tester and Comparators. The calibration systems manufactured by Budenberg are used in laboratories and workshops throughout the world.
Support for calibration equipment is covered with Budenbergs extensive range of repair, overhaul, and re-certification services to National and UKAS standards.
Budenbergs unique dual-range piston-cylinder units have been designed to operate as two units in one.
Rather than use one unit and weights to test for low pressure and a separate unit and weights to test for high pressure. You can now use just one piston unit for the calibration of both high and low pressure, saving you both time and money.
Ranges of Pressure for Calibration
• Hydraulic Dead eight Testers in ranges up to 1- 7,000 bar
• Pneumatic Dead Weight Testers in ranges up to -1 to 120 bar
• Hydraulic / Pneumatic / Electronic Comparators
• Repair, Overhaul, and Re-certification of Deadweight Testers to National and UKAS standards.

what type and brand of oil is best to be used? Thanks.

[@BudenbergGauge]

ISO VG22 mineral oil is preferred. Higher or lower viscosity can be used but may affect the performance.
