BGP1 Range: 15 – 1000 mbar

Pneumatic Dead Weight Testers - Model BGP1

1.5 – 100 kPa / 5 – 400 in.water / 150 – 10,000 mm.water

The design has been proven over many years to provide excellent sensitivity and stability. Low start pressure is achieved through use of a hollow piston and aluminium head. The Model BGP1 can be used to measure vacuum with a model 24 adapter. The BGP base can be used with any BGP series pistons, allowing testing from 1 kPa to 12 MPa.

The base requires a supply of gas slightly above test pressure, and has precision inlet / outlet valves and a screwpress to enable easy regulation and adjustment of pressure.
