A height gauge is an instrument placed on a platform, ideally a granite platform, for single-axis measurements. It is a full-featured measurement system that combines a platform with an altimeter. The full-featured altimeter is mainly used for online or batch testing, and can be measured directly on one or a group of machine tools, especially for workpieces with high size requirements. It is very useful for debugging and sampling inspection during production.

The laser level is mainly used to measure the height difference of the ground benchmarking point. The laser level's working principle is to set a horizontal plane and scan the laser on this horizontal plane, and then use the receiving target to receive it. When the center of the receiving target is consistent with the elevation, it can be read according to this level. Out of the elevation; therefore, the laser level can be operated by one person. In the construction industry, the spirit level is an indispensable measuring tool, which can measure the horizontal position, vertical position, and inclination angle of equipment installation.

A particle counter is an instrument that uses the principle of light scattering to count dust particles. Light scattering is related to factors such as particle size, light wavelength, particle refractive index, and particle absorption characteristics of light. However, in terms of the intensity of the scattered light and the size of the particles, there is a basic rule that as the surface area of the particle increases, the intensity of the scattered light of the particle increases.

Many users don't know how to operate the digital crane scale when they first use it. In the process of use, various problems may occur, which will lead to inaccurate weighing. The inability to display accurate data on the weight of objects will reduce the user's work efficiency. Next, SISCO will introduce in detail how to use the digital crane scale correctly.

Laser levels are a mainstream tool typically used in the construction and surveying industry for leveling and aligning applications. They project a constant red or green line onto a surface on a horizontal or vertical plane and can be used for anything from hanging a picture to professional building work.

Before using the spectrophotometer, the user should first understand the structure and working principle of the spectrophotometer, as well as the functions of each control knob. Before turning on the power, you should check the safety performance of the instrument. The power wiring should be firm, and the power should be good. The initial position of each adjustment knob should be correct and then press the power switch.

Thermocouples are a popular component for measuring temperature. Generally, the hot-selling thermocouples have good performance, such as a very wide range of temperature measurements, stable performance, accurate accuracy and no influence of media, etc. So how can we choose the right thermocouple?

A handheld metal detector is an instrument for detecting small metal objects. It can detect all kinds of metal objects hidden in the human body, including jewelry, electrical components, etc. Because of the metal detector's small size, lightweight, and ease to carry, it is widely used as an indispensable tool for personal inspection in security inspections.

Metal tube variable area flow meter is a traditional variable cross-section flow meter, which has many advantages such as simple structure, reliable operation, small and stable pressure loss, and can measure low flow rate media. It is widely used in measuring high temperature, high pressure, and corrosive fluids. medium. As determined by the measurement principle of the metal tube flow meter, it generally needs to be installed vertically. However, in some specific industrial applications, it is necessary to use a horizontally installed rotameter. Although the measurement principle is the same as the classic vertical rotameter, It is a rotameter with a special structure that can be installed in horizontal pipelines.

The dead zone is the region of time where the tester is temporarily blinded by a large amount of reflected light until it recovers and can read light again. Since the optical time domain reflectometer (OTDR) works by calculating the length of the cable and the point of failure based on time, a large number of reflections will cause the tester to take more time to recover, which creates a dead zone. The limitations of dead zones make optical time domain reflectometers (OTDRs) largely incapable of troubleshooting.
