These dual column testers allow instant range changes no need to change pistons.
Dual Column Testers Offer Fast Range Changes
This series of dual column deadweight testers provides NIST traceable pressure standards for gauges, indicators, and recorders. The testers are easy to set up and use and are ideal for both laboratory and field applications.
These units feature separate columns for high and low pressure measuring piston/cylinder assemblies. You can change ranges quickly using a built-in crossover valve rather than a piston change on single column models. The dual volume pump delivers high pressures with minimum effort.
