There are many types of measuring tools, which can be divided into the following categories according to different measurement needs and scenarios:
1. Length measuring tools
Vernier caliper: used to measure length, inner and outer diameters, depth, etc., with medium accuracy, simple structure and easy use.
Micrometer: more precise than vernier caliper, can measure the thickness, diameter and length of small-sized workpieces with an accuracy of up to 0.01mm.
Laser diameter gauge: uses laser technology for non-contact measurement, suitable for measuring the outer diameter and spacing of objects, with high accuracy and high speed.
2. Angle and distance measuring tools
Horizontal angle measuring rangefinder: integrates laser angle measurement, distance measurement, height measurement, speed measurement and other functions, suitable for construction, surveying and mapping, outdoor sports and other fields.
Total station: integrates photoelectric measurement, automatic calculation and data processing functions, can measure horizontal angles, vertical angles, distances and height differences, and is widely used in engineering measurement and geological survey.
3. Temperature measurement tools
Thermocouple thermometer: Uses thermoelectric phenomena to measure temperature, suitable for high and low temperature measurements, and has a wide range of industrial applications.
Resistance thermometer: Made based on the characteristics of resistance value changing with temperature, with a measurement range of -260℃ to 600℃.
4. Other special measuring tools
Inner diameter gauge: Used to measure the diameter of inner holes, with high precision, suitable for inner hole measurement during processing and inspection.
Level: Used to measure the height difference between two points on the ground, divided into precision level and ordinary level, suitable for construction engineering and topographic mapping.
Theodolite: Measures horizontal and vertical angles, suitable for engineering layout and angle measurement.
5. Multi-function measuring tools
Multimeter: Used to measure voltage, current and resistance, and is an important tool in the field of power electronics.
Sound level meter: Used to measure noise, simulating the response characteristics of the human ear to sound waves.
The above tools cover measurement needs in multiple fields such as length, angle, temperature, and electricity. Users can choose the appropriate tool according to the specific scenario. If you need to know more about a certain type of tool, you can search for vernier calipers or total stations.
