The sound level meter also called the noise meter, is an instrument used to measure the sound pressure level or sound level of sound, is the most basic and most commonly used instrument in acoustic measurements, with the development of the national economy and the improvement of people's material and cultural living standards, noise census and environmental protection work carried out comprehensively.  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 pH meter is an instrument used to test the acidity or alkalinity of a solution by measuring the active concentration of hydrogen ions (H+) in an aqueous solution to determine its acidity or alkalinity. A pH meter is a precision electrochemical instrument used to measure the concentration of hydrogen ions in dissolved liquids. It utilizes the physics of the response of an electrode to H+ ions at different temperatures and pressures. The value measured by a pH meter is called the "pH value", which usually ranges from 0 to 14, with smaller values indicating a more acidic pH, and larger values indicating a more alkaline pH.

Pressure gauge refers to the elastic element as the sensitive element, measuring and indicating higher than the ambient pressure of the instrument, the application is extremely common, it is almost all industrial processes and scientific research fields. In the heat pipe network, oil and gas transmission, water supply and gas supply system, vehicle maintenance workshop and other fields can be found everywhere. Especially in the industrial process control and technical measurement process, the mechanical pressure gauge of the elastic sensitive element has high mechanical strength as well as production convenience and other characteristics, so the mechanical pressure gauge has been more and more widely used.

An anemometer is an instrument that measures air velocity. There are many types of it, and the most commonly used one in meteorological stations is the wind cup anemometer, which consists of three parabolic empty cups fixed on the bracket at 120° to each other to form the sensing part, and the concave surfaces of the empty cups are all in one direction. The entire sensing part is installed on a vertical rotating shaft, and under the action of wind force, the wind cup rotates around the rotating shaft at a speed proportional to the wind speed. Next, we will introduce you to the knowledge of anemometer.

A magnetic flow meter is a type of flow meter that measures the flow rate of a liquid or slurry by measuring the voltage generated when the liquid flows through a magnetic field. We should not only know what the electromagnetic type flow meter is, but also have some points to pay attention to when installing it. In the following, we will give you some tips about installing this type of flow meter.

A thickness gauge is an instrument used to measure the thickness of materials and objects. It is often used in industrial production to continuously or sample the thickness of products (such as steel plates, steel strips, films, paper, metal foils, etc.). There are many types of thickness gauges, including coating thickness gauges, radioactive thickness gauges, ultrasonic thickness gauges, eddy current thickness gauges, and thickness gauges that use the principle of mechanical contact measurement.

The push-pull gauge has high resolution and high precision and can see three measurement units of N, Kgf, and LBF at the same time. The push-pull gauge has good operability and cooperates with the test machine. The push-pull force gauge is a mechanical measuring instrument for thrust and pulls tests, and it is widely used in High and low-voltage electrical appliances, electronics, hardware locks, auto parts, pens, light industry, construction, fishing gear, textiles, chemicals, machinery, IT and other industries and scientific research institutions for tension and compression load, insertion force test, destructive test, etc. It is a new generation of digital tension and pressure testing equipment.

Height gauges are also known as height vernier calipers. As the name suggests, its main purpose is to measure the height of workpieces, and it is also often used to measure shape and position tolerances, and sometimes to mark lines.

Digital storage oscilloscope is a kind of digital equipment with storage function, which adopts digital circuit for analog/digital conversion, and realizes the memory of the signal before triggering through the memory. In addition to the functions of an analog oscilloscope, a digital storage oscilloscope also has unique advantages such as waveform triggering, storage, display, measurement, and waveform data analysis and processing.

The earth resistance tester is a common instrument for testing and measuring grounding resistance, and it is also an indispensable tool for an electrical safety inspection and complete acceptance of grounding projects. Due to the rapid development of computer technology, ground resistance testers have also penetrated a large number of ground resistance tester microprocessor technology, and their measurement functions, content and accuracy are unmatched by general instruments.
