Main features of equipment:

1. Measurement system:

1) It is a kind of fully automatic measuring system, which can guarantee the accuracy automatically, and can easily measure the accuracy of + / -0.2% of the display value, and the most powerful characteristics is the fine resolution.
2) America branded-Force transducer  (with automatic set).
3) Automatic standard force, standard long calibration system, can be carried out by any metro-logical department for dumpster calibration (add some standard force, enter password, and keep the length calibration standard).
4) Automatic measuring system

2. Mechanical structure:

1) It adopts gantry frame structure and has the gap of the high precision ball double wire rod load to ensure rigidity and load on the machine efficiency. It has a larger test space, used for all kinds of tests. To guarantee the big load test function of the machine, it has the advantage of easy operation.
2) The bearing is imported from Japan, the synchronous belt is also imported, and there are many stainless steel components provided for the shell.
3) Low-resistance laser calibration measurement and elongation system.
4) The encoder of the patent structure does not need to disassemble (the limit is the German position sensor) in the high and low temperature box.

3. Driving device:

The motor is the British dc servo torque motor (which has the feature of anti-overload).

4. Data system:

1) The Chinese Windows xp version of the software can be upgraded at any time, and it adopts curvilinear color inkjet printing which can produce the most advanced software output color curve reports.
2) During the test, it can display real-time load, deformation, displacement, speed, maximum strength, breaking strength, elongation at break, tensile modulus and other test data (with the function of plastic function) and stress - strain curve. It can automatically save, read, analyze, amplificate, calculate, judge, add up, etc. the test results.


               Air Aging Test Chamber

Air aging test chamber adopts the hot air circulation way to prompt specimens to get aging. The inner carton has a strong sealing performance, and there is a exhaust chamber inside the device. It will automatically cut off the protection device when being over heated, which conforms to the requirements of the ul - 1581 test.
