仪器简介：
Cell Oven EB 01, with four cells. 
The test piece holder in each cell can take up to 24 standard test   
pieces. The high temperature accuracy is achieved by using an 
aluminium block with channels for preheating of the air.

主要特点：
EB 01 LTP with built in programmable water cooling. This version of the oven can operate between 20 °C to 200°C, which is very interesting for testing of stress relaxation.

The cooling makes it possible to conduct automatic relaxation tests according to ISO 3384 method B, where the ageing is done at elevated temperature but the counter force is measured at room temperature.
The temperature cycle is controlled from the PC-computer running the relaxation tests
