Welcome to Ji'nan Bojian Testing Machine Co., Ltd.

The microcomputer controlled electrohydraulic servo manhole cover pressure testing machine is mainly used for the residual deformation and compression strength test of the well cover.The testing machine adopts the advanced technology of wide speed range servo valve and computer numerical control, which can automatically and accurately measure and control the whole process of test machine loading and unloading.All kinds of test parameters are controlled, measured, displayed, processed and printed by computer.
