YC-SSJ-16 Fully Automatic Concrete Shrinkage and Expansion Instrument

[Overview]

During the hardening process of concrete, volume changes also occur. When hardened in air, the concrete will shrink (except for expansive cement). When hardened in water, the volume of concrete remains unchanged or undergoes very small expansion. This instrument can be used by building science research institutions, design departments, relevant laboratories, and construction units to measure the shrinkage and expansion deformation of concrete.

This model of shrinkage and expansion instrument adopts the latest high-speed ARM microprocessor core, embedded with real-time OS, comprehensive software functions, 7-inch full-color touch display screen, fully Chinese display, whether debugging or testing, easy to operate and learn. Intelligent microcomputer control realizes the automation of the working process, easy operation, high precision, stable speed, reliable performance, and beautiful appearance.

Mainly used for fully automatic recording of relevant parameters such as shrinkage and expansion of concrete, mortar or masonry brick specimens. The instrument comes with a built-in lithium battery for easy use while moving, and can perform tests on 3-16 samples simultaneously. The instrument can store five consecutive sets of test data (with a test period of 14 days and a total of 16 channels, each channel saving data every 10 minutes). After exceeding the number of experiments, it will overwrite the data saved in the previous experiment.

[Instrument Features]

The newly designed header alignment structure can achieve simultaneous adjustment of three axes, ensuring accurate measurement of the test piece.

Users can choose the number of channels as needed, and up to 16 channels can work simultaneously. The touch screen displays real-time current data from up to 16 channels, and the system is equipped with high-precision temperature and humidity sensors to display real-time current experimental environment parameters.

The controller can work independently. The controller saves the test data after power failure, and users can retrieve historical data to view and export it from the computer.

7-inch color touch screen display, real-time viewing of test data.

Optional PC software, complete data download management, view historical data and curve graphs, and print and output reports.

The main controller is equipped with a large capacity lithium battery pack, which can work continuously for at least 60 minutes without external power supply, avoiding unexpected power outages and other situations that may affect the progress of the test.

An independent collector collects data from each channel, using RS485 communication with high transmission reliability for precise and fast data transmission.

YC-SSJ-3 type: supports 3 specimen tests simultaneously.

YC-SSJ-16 type: Supports 16 specimen tests simultaneously.
