The leak detector for water is a device specially used to detect water leakage in water supply pipelines and other pressure pipelines. Different types of pipe detectors may use different technologies, which can be roughly divided into two types: using sound wave conduction and signal processing technology to locate the leak point.

A dew point meter is a precision instrument used to measure the moisture content in a gas. It determines the moisture content by measuring the dew point temperature in the air. The dew point temperature refers to the temperature at which the gaseous water in the air needs to drop to reach saturation and condense into liquid water under a fixed air pressure. It is an important indicator for measuring the humidity level of the air and is the balance point between the water vapor saturation and temperature in the air. The dew point temperature is not only important in weather forecasting but also plays a key role in industrial production, agriculture, and other fields. Therefore, the dew point meter also has a wide range of applications.

A surface roughness tester is an instrument used to measure the surface roughness of an object. It evaluates the smoothness and roughness of an object's surface by measuring the tiny fluctuations on the surface. Surface roughness testers are widely used in machinery manufacturing, the automotive industry, aerospace, and other fields, and are very important for ensuring product quality and performance. This article will briefly explain its working principle so that users can better understand the surface roughness meter.

Infrared thermometer is an instrument that uses infrared radiation energy to measure the temperature of an object. It is mainly composed of an optical system, a detector, a signal processing circuit and a display device. The working principle of an infrared thermometer is mainly based on the thermal radiation characteristics of an object and the relationship between thermal radiation energy and temperature.

Water activity meter is an instrument used to measure the water activity in samples. It is widely used in food, medicine, feed, chemical industry and other industries. This article will introduce the principle of water activity meter in detail from the aspects of water adsorption, infrared drying method, chemical method, vapor pressure method, refractive index method, coulometric method, thermogravimetric method, Raman spectroscopy, etc.

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.

A laser distance meter is an instrument that accurately measures the distance to a target using laser technology. During operation, the laser distance meter emits a thin laser beam towards the target, and the reflected laser beam is captured by photoelectric components. The timer measures the time it takes for the laser beam to travel from emission to reception, calculating the distance from the observer to the target. Laser distance meters are known for their lightweight, compact size, simple operation, speed, and high accuracy, with an error rate only one-fifth to a few hundredths compared to other optical range finders. In this article, sisco will introduce the working principles of laser distance meters for a better understanding.

Linear scale is a kind of sensor widely used in measurement and positioning systems, which realizes high precision measurement by detecting the phase change of light. This linear scale usually consists of a light source, a grating, a detector, and a signal processing unit, and has the advantages of high precision and fast response speed. The following is a detailed article from the sisco store about the working principle of linear scale.
