Introduction: The non-contact concrete shrinkage deformation tester conforms to the national standard GB/T 50082-2009 "Test method for long-term performance and durability of ordinary concrete". It is suitable for measuring the free shrinkage deformation at any time after self-forming, and can also be used for concrete in an unconstrained state. Determination of self-shrinking deformation at early age without moisture exchange from the outside world. The non-contact displacement measurement technology is used to obtain the free shrinkage deformation of concrete specimens in any period of time, and to accurately evaluate the "free shrinkage and self-shrinkage" deformation characteristics of early-age concrete. The application field of non-contact concrete shrinkage deformation tester is concrete technology research, concrete production, quality supervision and inspection departments, and engineering departments such as hydropower, highway, railway and other engineering departments need to measure the shrinkage and deformation of concrete. Features: 1. Number of test groups: 1 group (3 specimens per test group, 6 displacement sensors); 2. The data will not be lost when the power is cut off, and the operating state before the power cut will be automatically restored after restarting; 3. There is an integrated temperature and humidity sensor to synchronously monitor the ambient temperature and humidity of the experimental site; 4. Fully automatic data acquisition, with data export function for later data processing; 5. Real-time display of various indicators in tabular form, and can be printed and stored. 6. It adopts large-screen touch display screen, man-machine interface, and convenient operation. Technical parameter: 1. Detection time interval: 1-120 minutes can be set; 2. Displacement measurement range: 3.0mm 3. Test accuracy: ±0.002mm; 4. Working temperature: 0℃—+40℃; 5. Working power supply: AC220V50HZ 6. Working environment: meet the requirements of the experiment, the experiment requires constant temperature and humidity; 7. Sampling interval: the minimum 1min, can be set arbitrarily, and the stored data can be permanently saved indefinitely. 8. Display: Large LCD touch screen
