Supply Dongying Level

DSZ2 can be used to state three or four other standard observations, meet a variety of engineering and construction standards of measurement requirements. The product provides automatic compensation function, can greatly improve operational efficiency and to avoid errors. DSZ2 + FS1 can be used to state a second-class standard of measurement and precision measurement of subsidence and deformation. 

 Features: 
 ? check button compensator 
 ? sealing against dust, easy to operate 
 ? compact structure, beautiful appearance 
 ? can be equipped with micrometer level, can be used for national secondary standard of measurement and precision settlement observation 
 ? Excellent temperature compensation performance 

 We all know that compensation is made of metal and glass materials, components, and these materials affected by temperature, will cause changes in trace compensator, resulting in i angle changes. Without temperature compensation equipment, often can not meet the national standard GB / T 10156-4997 requirements. The figure in the green area within the boundaries of the red line for the temperature change when the compensator qualified area (enterprise standard: ± 0.5 "/ ° C). Thick red curve in Figure A is not temperature compensated water level i angle curve. DSZ2 has been added to the temperature compensation device, the use of temperature compensation devices on the i angle variation with temperature correction, shown in green bold line B is compensated by the i angle curve, so that the instrument in a larger temperature changes adverse conditions can also meet the requirements for a long period of deformation observation is particularly applicable.
