A laser level operates by emitting a beam of laser light and features a highly accurate horizontal measuring device. It can be utilized to determine the verticality of surfaces such as floors, walls, or reference planes. Serving as an instrument for measuring and controlling the horizontal plane, it finds extensive applications in various scenarios including construction, decoration, interior design, bridge construction, precision positioning of CNC machine tools, wall tiling, leveling measurements, mechanical manufacturing, and more. In this article, sisco will introduce how does the laser level work, to help you have a better understanding of it.

The Optical Time Domain Reflectometer (OTDR) is an essential tool for fault location and performance evaluation in optical fiber networks. This article, sisco will provide a detailed explanation of the working principles of OTDR, including the basic principles, measurement principles, and data analysis principles.

A measuring tape is a common measuring tool, and its working principle involves using the scale on the tape and the length of the tape to measure dimensions such as length, width, and height of objects. While using a measuring tape is convenient, its working principle is not as simple. Below, Sisco will explore the working principle of a measuring tape from the perspectives of mechanical principles, material science, and mathematics.

The measuring tape is one of the commonly used measuring tools in our daily lives. Whether for home renovations, construction projects, or crafting, a measuring tape is essential for dimension measurements. However, with numerous brands and models available in the market, the choices can be overwhelming. In this article, Sisco will guide you on how to select and purchase a measuring tape that suits your needs.

A measuring tape is a common measuring tool primarily used to measure the dimensions of objects, including length, width, and depth. Widely employed in various fields such as engineering, construction, and home improvement, the measuring tape is essential for diverse measurement tasks. In this article, sisco will explore the usage and readings of the measuring tape to assist readers in employing it correctly and accurately for measurements.

Phase Testers, also known as Phase Sequence Testers or Phase Rotation Testers, are electrical testing devices used to determine the phase sequence (order) and phase rotation (direction) of the voltage in a three-phase electrical system. Phase rotation and sequence are critical factors in ensuring the proper and safe operation of motors, machinery, and electrical equipment in three-phase systems.

A sound level meter (SLM) is an instrument (usually hand-held) used to measure sound levels in a standardized manner. It responds to sound in much the same way as the human ear and can objectively measure sound pressure levels.A sound level meter is an instrument used to measure the intensity of sound, and it is important in many different fields and applications. The machine manufacturing industry has taken the noise as one of the important quality indicators of the product, auditoriums and gymnasiums, and other buildings do not only require the shape of the beautiful but also the pursuit of acoustics, all of which makes the sound level meter is more and more widely used. The buildings such as auditoriums and gymnasiums not only require beautiful shapes but also pursue acoustic effects, which make the application of sound level meters more and more widely.

A hardness tester is an instrument designed to measure the hardness of a material, which is the material's resistance to permanent deformation, indentation, or scratching. Hardness testing is commonly used in various industries, including metallurgy, manufacturing, engineering, and quality control, to assess the hardness characteristics of materials. In this article, sisco will list the price of corded circular saws for your reference.

A hardness tester is an instrument used to measure the hardness of materials, commonly employed in hardness testing of various materials such as metals, plastics, and rubber. However, due to prolonged use or improper operation, the hardness tester may encounter some issues. In this article, sisco will introduce common problems with hardness testers and their corresponding solutions to help users better maintain and utilize hardness testers.

A bimetallic thermometer is a common sensor used for measuring temperature. It is composed of two different metals stacked together, and their slight deformation due to differential expansion rates caused by temperature changes is used to measure temperature. In this article, sisco will introduce the working principle, structure, features and applications of bimetallic thermometers.
