Silicone Conductive Resistance TesterIt is a precision instrument specifically used to measure the conductivity of silicone materials. Its core principle is based on Ohm's law, which calculates the resistance value of silicone by applying voltage and measuring current, and further determines the volume resistivity by combining sample size information. This tester has high-precision measurement capability, with measurement error controlled within ± 0.5% and a wide measurement range of up to 10 ΩΩ to 10 ¹² Ω. It can meet the resistance testing needs of different silicone products, such as silicone buttons and conductive silicone strips in electronic devices. The use of four wire measurement technology effectively eliminates errors caused by wire resistance and ensures the accuracy of measurement results.
Silicone Conductive Resistance TesterThe components of:
1. Host: As the core control unit of the tester, the host integrates key components such as high-voltage power supply, microcurrent detector, embedded microcontroller system, etc. It is responsible for applying test voltage, measuring current values, and calculating resistance values based on Ohm's law. It also supports parameter setting, function conversion, and data storage and display.
2. Electrode (fixture): The electrode is a key component that directly contacts the silicone sample, and its design directly affects the testing accuracy. According to testing requirements, electrodes can be divided into various types such as circular three electrode, flat electrode, fixture electrode, etc. Circular three electrodes are suitable for sheet-like and thin-film samples, and can simultaneously measure volume resistivity and surface resistivity; Flat electrodes are suitable for block or cylindrical samples; Clamp type electrodes can be customized according to the shape of the sample to ensure uniform compression.
3. Connection cable: The connection cable is responsible for connecting the host with components such as electrodes and power supply, ensuring stable signal transmission. High quality connecting cables usually adopt shielding design to reduce the impact of external electromagnetic interference on test results.
4. Shielding box (optional): For high-precision testing or complex electromagnetic environments, the shielding box can effectively isolate external interference and improve the accuracy of test results. It is usually made of metal material and coated with a conductive layer inside, forming the Faraday cage effect.
5. Software system (optional): Some high-D testers are equipped with professional data analysis software, which supports real-time recording and analysis of measurement data, and generates detailed test reports. These reports include key information such as measurement time, measurement values, mean values, standard deviations, etc., which facilitate users to comprehensively evaluate the conductivity and resistance performance of silicone products.
6. Auxiliary accessories: such as insulated gloves, tweezers, cleaning tools, etc. Although these accessories are not core components, they also play an important role in the testing process. Insulated gloves and tweezers are used to secure samples and avoid contamination; The cleaning tool is used to clean the electrode and sample surface, ensuring the accuracy of the test results.
