Metal detectors are widely used in examinations, security checks, archaeology and prospecting, etc., bringing more convenience to people's lives. So how do metal detectors accomplish these tasks? Next, ATO will introduce the working principle, application and structure function of the metal detector to you.

Before using the pH electrode, it is very necessary to perform numerical calibration on it. The pH electrode calibration method refers to a method to make the measurement results of the pH electrode more accurate and reliable through a series of operations. Its main steps include cleaning the electrode, calibrating the electrode and judging whether the electrode needs to be replaced.

A Height Gauge measures the height of a workpiece, it is a measuring instrument in which a slider with a measuring stylus moves relative to a measuring scale on a beam, and in which this motion is along a single vertical axis nominally perpendicular to a reference plane on the instrument base. Height gauges are normally used on a granite surface plate to measure and/or scribe part features from a datum plane. Generally, a scriber, Dial test indicator, and Dial indicator are used to locate the measured feature. Height gauges are an indispensable instrument for quality control.

The push-pull gauge is a mechanical measuring instrument used for push and pulls tests. The push-pull force gauge is suitable for push-pull load tests in industries such as electronic appliances, light industry textiles, construction hardware, lighters and ignition devices, fire-fighting equipment, pens, locks, fishing gear, power machinery, scientific research institutions, etc.

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.
