Micro Thickness Tester

The micro thickness gauge measures material thickness using ultrasonic or eddy current principles. The probe contacts the sample, emits a signal, and receives the echo, calculating the thickness value based on the time difference. It is used for rapid on-site inspection of coatings, films, plates, etc., to verify whether the thickness meets standards during quality control and maintenance.
Selection
When selecting a micro thickness gauge, consider the material type, such as metal or non-metal, and match it with ultrasonic or eddy current technology. The measurement range should cover the sample thickness, and accuracy must meet error requirements. The probe size should fit the inspection area, while environmental factors like temperature must be accounted for. Portability and battery life should also be suitable for on-site use.
