Product Description

Product Description

                                                                                              Low-temperature brittleness testing machine

An imported fully enclosed compressor is used as the low-temperature refrigeration source, replacing the traditional carbon dioxide dry refrigerant as the cooling method for the cold bath.
The compressor: uses an imported well-known brand, enabling the temperature to reach the set temperature (-73℃) and remain stable throughout the test process.

The temperature is stabilized by using a liquid medium (such as anhydrous ethanol). After the temperature is stable, the sample is quickly placed in it, and it can return to the test temperature within 5 minutes.

Details introduction:

The box body is made of 1.5mm steel plate. The protective coating is produced by electrostatic spraying followed by high-temperature baking. The thickness and adhesion of the paint film comply with the national standard GB/T9286-198.
The color of the box body: the upper part is dark gray, the lower part is white. (The spring method has red padding)
The bottom is equipped with universal moving casters for easy positioning.
