An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials.
A Vickers hardness test is the most accurate way of determining hardness in a variety of materials, which is why we use this test on all raw materials and on the hardened layer of the finished product surface.
To ensure that each batch of products perfectly satisfies customer requirements, World Hardware（CHE） employs special laboratory and testing personnel to strictly control the quality of each process from in coming testing to finished-product testing.
When fastening various thread fasteners, we should control the applied torque to ensure the fastening thread has no damage caused by a large torque. This is achieved simply by turning a wrench.
Through the application of this optical projector, we can efficiently test the outline and surface shape of various complicated fasteners.
This screening machine is also used to automaticly sorting out the defects, in appearance and critical dimensions, which can make our produced parts pass 50DPPM defect rate. It is more economic and efficient compared with manual sorting.
Through artificial simulation of salt spray conditions, this salt spray corrosion chamber can test the corrosion resistance of our products to guarantee the durability under different conditions.
