What is a heavy hammer resistance meter
source：English website | Release time：2025年07月17日1. Working principle
By striking a metal hammer on the surface of the object being tested, a closed circuit is created. The measuring instrument detects the current flow between the upper and lower electrodes in the tapping area, and then calculates the resistance value of the object surface.
2. Main features
Accurate measurement: By combining the methods of heavy hammer striking and current measurement, high-precision and accurate measurement results are ensured, and some high-precision instruments can control errors within ± 5%. And the measurement range is wide, usually from 1 × 10 ² ohms to 1 × 10 ¹ ² ohms.
Easy to operate: usually equipped with an easy-to-use user interface and intuitive display screen, operators can easily conduct tests and read results; It also provides multiple testing modes such as automatic and manual. In automatic mode, the testing process can be completed automatically, reducing human operation errors and improving testing efficiency; Manual mode allows users to more flexibly control test parameters.
Versatile functions: In addition to measuring surface resistance, some heavy hammer surface resistance testers can also measure grounding resistance, conductivity, etc; Some instruments can also simultaneously test and record environmental temperature and relative humidity, facilitating the analysis of the impact of the environment on resistance measurement.
Efficient testing: With just one tap, the resistance value of an object's surface can be quickly measured, saving time and labor costs. It also has fast testing speed and can complete a large number of measurement tasks in a short period of time.
3. Application Fields
Heavy hammer resistance meters are widely used in fields such as electronics, electrical, communication, chemical, aerospace, etc., to measure the surface resistance values of various electromagnetic shielding materials, conductive materials, touch screens, glass, etc. In the electronics industry, it is used to detect the surface resistance of electronic components such as circuit boards and semiconductor chips; Assist enterprises in evaluating the performance of anti-static materials in the field of electrostatic protection; In the chemical and textile industries, it is used to test the insulation performance of materials.
