Performance features:

The instrument features a novel, luxurious, and elegant appearance, is simple to operate, convenient to use, delivers accurate test results, and boasts powerful functionality.

We offer high-precision pressure sensors with capacities of 5 kN and 100 kN, as well as two high-precision displacement sensors. These displacement sensors can simultaneously measure deformations in both horizontal and vertical directions, making them suitable for a wide range of tests involving different pressure ranges and various displacement orientations. The instrument employs a servo system for loading and features automatic measurement and control via computer. The loading speed range is from 1 to 100.0 mm/min.

Pressure Sensor Replacement: To conduct different experiments, you’ll need to use pressure sensors with varying measurement ranges. The instrument employs a machining center’s automatic tool-changing technology to seamlessly switch between pressure sensors—simply click the corresponding sensor icon on the computer screen (as shown in the figure below). The instrument automates the sensor replacement and installation process in an unbelievably convenient way, eliminating the need for tedious manual disassembly and reinstallation of pressure sensors.

Improved 2nd-generation model, environmental chamber temperature range: -30 Celsius ~70 Celsius It provides users with a lower experimental temperature environment, making it ideal for testing and experiments in regions with extremely cold climates. Featuring a double-door insulation design, it effectively prevents cold air from escaping when the door is opened. Its unique and scientifically engineered airflow circulation system ensures minimal temperature differences and low temperature fluctuations within the chamber, maintaining overall temperature stability.

The entire testing process is automatically conducted by a computer, which displays the stress-strain curve in real time. Upon completion of the test, the computer automatically performs an “O”-point correction on the curve and automatically calculates various test results, generating a comprehensive test report. This eliminates measurement errors and ensures high accuracy. The test results are automatically saved by the computer, and the device features USB, Ethernet, and wireless Wi-Fi interfaces. Additionally, specialized test analysis software provides users with more advanced and professional technical support.
