1. Electronics Manufacturing Industry

In semiconductor chip production workshops, handheld surface resistance testers are widely used to detect the surface resistance of chip production equipment. For example, on the production line, the surface of wafer transfer equipment needs to maintain specific electrostatic dissipation properties. By using the tester, the technical staff can regularly check whether the surface resistance of the equipment is within the safe range (generally, the surface resistance is required to be between 10^6 and 10^9 Ω). If an abnormal resistance value is detected, they can take timely measures such as cleaning the equipment surface and replacing anti-static components.

2. Automotive Manufacturing Industry

In the automotive painting workshops, electrostatic spraying technology is widely applied. Handheld surface resistance testers can be used to detect the surface resistance of the vehicle body surface to be painted. An appropriate surface resistance of the vehicle body helps the uniform adsorption of paint particles and improves the painting quality. For example, when the surface resistance of the vehicle body is within a certain range (such as 10^8 to 10^10 Ω), the electrostatic painting equipment can make the paint adhere better to the vehicle body, reducing the orange peel phenomenon and paint waste.

During the production of automotive interior parts, some plastic and fabric materials also need to be tested for surface resistance. For example, the fabric of the car seat, by testing its surface resistance with the tester, it can be ensured that it meets the anti-static standards to prevent passengers from feeling uncomfortable due to static electricity when getting in and out of the car, and also to reduce dust adsorption caused by static electricity.

3. Medical Equipment Industry

In operating rooms and medical clean rooms, environmental control is crucial for patient safety. Handheld surface resistance testers can be used to detect the surface resistance of the operating room floor, the surface of the operating table, and the outer shells of various medical equipment. For example, the operating room floor needs to maintain good electrostatic dissipation performance, and the surface resistance is usually required to be between 10^6 and 10^9 Ω to prevent electrostatic discharge from causing medical equipment failures or harm to patients.

4. Chemical Industry

In chemical laboratories and production workshops, many chemical substances are very sensitive to static electricity. Handheld surface resistance testers can be used to detect the surface resistance of chemical reaction kettles, pipelines and other equipment. For example, during the production of flammable and explosive chemicals, the surface resistance of the reaction kettle must be kept within the safe range (such as 10^6 to 10^9 Ω) to prevent electrostatic discharge from causing fire or explosion accidents.

5. Aerospace Field

During the manufacturing and maintenance of aircraft, the surface resistance of the metal parts such as the wings and fuselage of the aircraft, as well as the electronic equipment and instruments in the cockpit need to be strictly detected. Handheld surface resistance testers can be used to check the conductivity and electrostatic dissipation ability of the aircraft part surfaces. For example, the surface resistance of the fuel system parts of the aircraft must meet strict standards (such as 10^6 to 10^9 Ω) to prevent electrostatic discharge from causing fuel ignition or explosion.
