The creep test machine is used to determine the concrete specimen deformation characteristics under long term constant axial load and constant temperature, humidity. This machine uses precision pressure transducer, displacement sensor for real-time monitoring. The test parameters are setup on touch screen, real time acquisition of deformation and ambient temperature / humidity value. The system can maintain constant pressure when set pressure reached, it can apply independent load to each specimen. Each test can be divided into 3 stage for pressure application, the test time of each stage can be freely set. It's an indispensible concrete durability test equipment.
LCD touch screen operation, real-time indication of test pressure, deformation, ambient temperature & humidity
Wi-Fi data transmission to computer
