低温压力试验仪

仪器简介：
Performing compression set at low temperatures without having to 
open the  deep-freezer and influence the compression set result has 
always been a problem.   

By using our EV 09 compression rig in combination with a deep-freezer
with a special lid the test can be performed without touching the test
piece. All adjustments of height and releasing the compression are 
made outside the freezer thus improving the accuracy of the test results.

主要特点：
Performing compression set at low temperatures without having to open the deep-freezer and influence the compression set result has always been a problem.

By using our EV 09 compression rig in combination with a deep freezer with a special lid the test can be performed without touching the test piece.

All adjustments of height and releasing the compression are made outside the freezer thus improving the accuracy of the test results.
The EV 09 rig has a digital gauge (0,001 mm), the piston is made of titanium and the test weight is simply mounted on to the titanium piston. The sample can remain in the test rig for the whole test period and during the recovery time.

The system is a complete system with rigs, a special adapted deep freezer and logging software. The values can also be recorded manually.

Existing users of our EB 02 stress relaxations rigs can buy an addition set which converts the rig to EV 09.
This conversion kit includes a compression plate with a rod, linear bearing, spacers, weights, digital gauge with 0,001 mm resolution and software for plotting the recovery.
