Suitable for most twin screw materials testing machines, the Tinius Olsen Environmental Chamber provides a means for performing physical tests within a temperature range of -70-300°C (-95-570°F). An internal radial fan provides efficient air circulation that minimizes temperature gradients throughout the chamber.
A digital controller ensures accurate temperature control. Optional sub-zero temperature testing is available via a self-pressurising liquid nitrogen Dewar.
The chamber door is fitted with a triple glazed window for viewing the test area and also scanning the sample for strain measurements when using the Tinius Olsen 500L laser extensometer. When liquid nitrogen is used, a demisting facility is fitted.
The chamber is supported on a frame located between the columns of the testing machine. When the chamber is not in use, the chamber can be rolled back and parked clear of the operating area.
