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.

A laser level is a kind of level that uses a laser beam instead of manual reading. There are two types of laser levels: special laser level and laser device attached to the level. It can be used for leveling measurement by cooperating with a leveling rod equipped with a photoelectric receiving target. Compared with the optical level, the laser level has the characteristics of high precision, long line of sight and automatic reading and recording.

The air quality monitor is a product that can detect formaldehyde, PM2.5, TVOC and temperature and humidity in real-time. It is small and exquisite and easy to carry. Through its internal sensor, it can accurately measure the concentration of pollutants and calculate the air quality index AQI, and alarm when the concentration exceeds the standard. The principle of the air quality monitor is to detect the signals of the front-end formaldehyde sensor, PM2.5 sensor, TVOC sensor and temperature and humidity sensor, amplify the weak signal of the sensor through the operational amplifier, and remove the noise interference through the filter circuit, then collect it through AD, and use 32-bit high-precision CPU processing and calculation, converted into pollutant concentration values, and displayed on the LCD screen.

The thermocouple is a commonly used temperature-measuring instrument. It directly measures the temperature, and converts the temperature signal into a thermal electromotive force signal, and converts it into the temperature of the measured medium through an electrical instrument (secondary instrument). The basic structure of thermocouples is roughly the same, usually composed of main parts such as thermal electrodes, insulating sleeve protection tubes and junction boxes, and used in conjunction with display instruments, recording instruments and electronic regulators.

Handheld metal detectors are designed to detect metal objects carried by people or objects. It can detect weapons, explosives, or small pieces of metal in packages, luggage, letters, fabrics, etc. carried by people. The special appearance of its sensitive surface allows easy handling. Superior to ring sensor hand probes. Ultra-high sensitivity, special application. Such as prisons, chip factories, archaeological research hospitals, etc. Handheld metal detectors are used to detect the specific location of metal carried by a person.
