Characteristics:
RDL series electronic creep relaxation testing machines adopt digital controller and software which was made by DOLI company(Germany), the measurement and control system is composed of measurement unit which developed specially by DOLI, the EDC controller, applicant software. The EDC controller is joined with PC by 232 interface to realize the computer control. Compare with other series creep testing machines, it has advantages of precision higher, performance better, software more convenient.
1. The mainframe adopts the loading structure of double column gate.
2. It uses the temperature controller with the 0.1 precision to control the temperature, EDC222 could communicate to the temperature controller, and control it , the whole testing process would not be disturbed by anyone.
3. The information of temperature overrun and time etc, could be sent to the administrator by the way of SMS.
4. The testing machines could match various environment testing device.
