high precision Foif Dsz2 Auto Level can be used for the state’s three or four level observation, to meet the requirements of various construction projects and leveling. This product has automatic compensation function, can greatly improve work efficiency and avoid mistakes. DSZ2+FS1 can be used in the state of one or two such as leveling and settlement deformation and other precision measurement.

Excellent temperature compensation performance
We all know that the compensator is made up of metal materials and glass materials, and these materials are affected by temperature, will cause the change of trace amounts of compensator, which leads to the change of I angle. Without the temperature compensation instrument, often can not meet the national standard 10156-4997 GB/T requirements. As shown in the figure within the boundaries of the red green area changes of temperature variation compensator qualified region (enterprise standard: + 0.5 “/ degrees Celsius). The red rough curve in the A is not the temperature compensation of the level of I angle change curve. I angle with temperature variation is modified, such as green thick line B to the compensation after I angle change curve, so as to make the instrument changes in temperature more harsh conditions can meet the use requirements, on long time observation of deformation is especially suitable for using a temperature compensation device was DSZ2 has added a temperature compensation device.
