Commonly used distance measurement methods include tape measure distance and photoelectric distance measurement. The measuring distance of a tape measure is measured along the ground using a tape-like ruler that can be rolled up, which is a direct measuring distance. Photoelectric ranging is to use an instrument to transmit and receive modulated light waves between two points, and measure the distance according to its propagation speed and time. It belongs to electronic physical ranging. Photoelectric ranging is indirect ranging.

In the society where the vehicle is the mainstream of the car; the quality of the car parts is of vital importance. Here are a few ways for you; for reference. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
There are data appearing; in the past three years of traffic accidents; because the use of counterfeit spare parts accounted for 13%. Therefore, grasp the identification of some fake and shoddy auto parts products; for those engaged in car driving or spare parts operations; very necessary .
1, look at the packaging. The original parts packaging is usually compared to the standard; unified standard standards; printed handwriting clearly on the track; and fake filling product packaging printing is inferior; often can easily find the loopholes from the packaging.
2, look at the color. Some original parts of the appearance specify a certain color; if other colors; then fake fake parts.
3, look at the appearance. The original parts of the external printing or casting and symbols clearly on the track; and the fake filling products look rough.
4, look at the paint. Unscrupulous traders will simply process the waste parts; such as dismantling, loading, spelling, scraping, painting, etc.; and then selling fake products; illegally obtaining high profits.
5, look at the quality. The original parts of the information is selected according to the needs of the description of the information; fake products are mostly used to sell defective data.
6, look at the process. The appearance of the defective product is sometimes good, but because of the poor manufacturing process; simple presentation of cracks, sand holes, slag inclusions, burrs or bumps. Cylinder block kneading deformation; simple use of the seal caused by abrupt and ablation Incurs the appearance of oil leakage, air leakage and water leakage, and the piston and piston ring work have a burr and simple pull cylinder.
7, look at the storage. If the auto parts are dry cracking, oxidation, discoloration or aging problems; may be in the storage side of the poor environment, long storage time, poor data and other reasons.
8, look at the joint. If the clutch plate rivet loose, brake tube degumming, electrical parts joint desoldering, paper filter joints off the surface, etc.; can not be used.
9, look at the logo. Some of the components on the track are marked with some marks; such as the gear symbol, the symbol of the top of the piston and other device symbols; to ensure that the machine is properly installed; no one can not be purchased.
10, look at the missing. The components of the track are necessary to be completely intact; the ability to ensure smooth installation and normal operation. Some small parts on the assembly are missing; usually "parallel imports"; these create a difficult device. Often due to a single Missing gadgets; forming the entire assembly parts void.
