Single Range Dead-Weight Tester 1 to 120 Bar

The BGH series base can be used with any of the BGH series pistons to give ranges 1-120 bar with a BGH120, 2-300 bar with a BGH300, 1-700 bar with a BGH700 and 1-1200 bar with a BGH1200. All units are top loading for ease of use and weight sets are fully interchangeable. This means that weight sets in alternative pressures are readily available and customers with more than one BGH series tester can interchange weight sets between testers of the same range.

The base features a dual area screwpress which allows low pressure priming and high pressure control. The BGH120 is a robust design, proven over many years usage. The unit has a 1/16in2 fully hardened and stabilized tool steel piston. This unit gives extremely good sensitivity for high accuracy calibration, yet is tough enough for regular use in a workshop environment.

All certificates issued for Budenberg Dead-weight Testers are fully traceable to national standards via equipment with UKAS calibration certificates. A standard accuracy of 0.015% is achieved from 10% of range using software supplied to compensate for the effects of gravity, temperature and the actual area of piston unit. Standard accuracy without any corrections for actual area is 0.02%from 12 to 120 bar, 0.03% from 1 to 12 bar. Higher accuracy Class A testers are available (supplied with UKAS Calibration certificates for area and mass) allowing an accuracy of 0.008% to be achieved.
