A floating arm mechanism (patent pending) ensures tests can be performed reliably without the arms disengaging from samples.
DSES-1000
Long-Travel Extensometer for Soft Materials

Das DSES-1000 ist ein berührender Langweg-Extensometer, der bei Zugversuchen an Gummi und anderen weichen Materialien die Dehnung bis zum Bruchpunkt messen kann. Der obere und der untere Arm werden mit einem einfachen Handgriff an den jeweiligen Messpositionen festgeklemmt, wobei jeder Arm die Dehnung der Probe unabhängig misst.
Features
-
The DSES-1000 can measure elongations up to 4000% for gauge lengths of 10 mm, 2000% for gauge lengths of 20 mm, 1600% for gauge lengths of 25 mm, or 1000% for gauge lengths of 40 mm.
A floating arm mechanism (patent pending) ensures tests can be performed reliably without the arms disengaging from samples. -
Offers ±0.2% precision for displacement measurements between 50 and 1000 mm, allowing measurement of long displacement distances can be measured with high precision.
-
The lateral quick clamping mechanism makes it easy to center the mounted position of extensometer edge with the sample.
The extensometer can also be attached to the sample first, before chucking the sample.
