The laboratory test benches BPR series have been designed to carry out flow-rate, leaktightness, sensitivity, fidelity, shut-off and endurance tests in accordance with International Standards.

Giussani's test benches have been conceived to operate in compliance with the most important international Standards: NF, KIWA, EN, UNI, ASME JAPMO, etc.
BPR-SWG serie test benches are equipped with workstation, 19" LCD monitor, electronic card, in order to allow the real-time analysis and recording all test parameters; each test can be displayed or stored together with the most significant diagrams; the supply also includes a color laser printer located on the bench.
The standard software package includes an acquisition card to read until 16 channel with high acquisition frequency adjustable from 300 to 1000 Hz.
The software for laboratory management can be integreted with the applications for management and acquisition of all optinal tests, which can be added both with devices installed on the bench.
