Product Name: Surface vibration compaction tester
Surface vibration compaction tester
Uses: In order to comply with the latest “Highway Geotechnical Test Procedures†issued by the Ministry of Communications (
JTJ051-93
Developed by the implementation of the method, mainly used to determine the maximum dry density of non-adhesive free drainage coarse-grained soil and giant-grained soil (including rockfill). The instrument adopts an upper pressure frame structure, which can effectively prevent the separation of the pellets. The instrument is equipped with automatic control and protection devices for easy operation and reliable operation.

Precautions for use:1.
When using the equipment, carefully read the technical manual, familiar with the technical indicators, work performance, use methods, precautions, and strictly follow the prescribed procedures of the instrument manual.
2.
For the first time, the equipment personnel must be operated under the guidance of skilled personnel, and they can be independently operated after being proficient.
3.
The equipment and equipment used in the experiment should be laid out reasonably, neatly arranged, easy to operate, observe and record.
4.
Before the electronic equipment is powered on, ensure that the power supply voltage meets the input voltage value specified by the equipment. The equipment with a three-wire power plug must be plugged into a protective earthing power socket to ensure safety.
5.
use
When the equipment is used, its input signal or external load should be limited to the specified range, and overload operation is prohibited.
6.
Optical chemical instruments and their accessories should be handled with care to prevent vibration. Do not touch the surface of the optical glass with your hands. When dust or dirt is found, do not wipe it with your hands or a rag. It must be removed with special products or special tools.

Wedge Prism can be used to deflect the laser beam at a certain angle alone, or combine the two together as beam deflection application. A single prism can offset the incident beam by a certain angle. If measured by diopter, it is a diopter, which is equivalent to an offset of 1cm at a distance of 1m
Ø can be used for beam deflection
Ø 0.5 ° - 15 ° beam deflection
Ø products without coating or antireflection coating are available
In addition, irregular prism pairs are also provided
Wedge prism can be used to deflect the laser beam at a certain angle alone, or combine the two together as beam deflection application. A single prism can offset the incident beam by a certain angle. If measured by diopter, it is a diopter, which is equivalent to an offset of 1cm at a distance of 1m
Two can be used as deformable prisms (to correct the elliptical beam output by the laser tube), or to set the beam at 4 θ Deflect at various angles within the range, θ It refers to the light deflected by a single prism. This beam shaping is realized by rotating two beams respectively, which is typically used to scan different positions in imaging.
