With the modular designed test box, a variety of objects can be safely pressurized, tested and monitored with minimal loss of valuable workshop space. The simplicity of the hydraulically opened lid and integrated thick walled plated steel, ensures a safe test environment for the operator in the workshop. The lid has a door lock and a door switch safety system. By use of a dual pump setup and multiple pressure transmitters the test box can generate test certificates for a wide range of test pressures.
