The BGH series base can be used with any of the BGH series pistons to give ranges 1 – 120 bar, 2 – 300 bar, 1 – 700 bar, 1 – 2000 bar. 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 weights sets between testers and of the same range.

The base features a dual area screwpress which allows low pressure priming and high-pressure control. The BGH1200PCH is a dual area piston/cylinder unit with 1/8in2 and 1/160in2 areas. Changing between ranges is fully automated meaning that users have an extremely flexible instrument covering the range with one piston/cylinder assembly and one weight set. The low pressure pistons /high-pressure cylinder is tungsten carbide, other parts are fully hardened and stabilised tool steel.
