Product Description High Voltage Switch Circuit Breaker Contact Resistance Tester KitProduct overview The contact resistance tester is a device used for measuring the electrical resistance of contacts, such as those found in electrical switches, relays, and connectors. It is used to ensure that the contact is making a good electrical connection and that the contact resistance is within acceptable limits. The contact resistance tester is a reliable and accurate device, making it an essential tool in any electrical testing laboratory. It is easy to use and provides precise measurements of contact resistance in a wide range of applications. What is contact resistance test Contact resistance test is a type of electrical test performed to measure the resistance between two conductive surfaces that are intended to be in contact with each other. It is commonly used in the electrical industry to ensure the safety and reliability of electrical equipment and connections.The test is typically performed using a contact resistance tester, which measures the resistance of the contact surface by passing a small current through it and measuring the resulting voltage drop. The device uses a Kelvin-type four-wire measurement technique that eliminates the effects of lead resistance and contact resistance, ensuring accurate and repeatable measurements.Contact resistance testing is important because high resistance at a contact point can cause a number of problems, including overheating, voltage drops, and loss of power. These issues can lead to equipment failure, safety hazards, and loss of productivity. By performing contact resistance testing, potential problems can be identified and addressed before they cause serious issues.Product usage - Manufacturing industry: Used to test the contact resistance of electrical components such as connectors, relays, switches, etc., during the manufacturing process, to ensure the quality and performance of the products.- Mining industry: Used to test the contact resistance of electrical equipment in mines, to ensure the safety and reliability of the mine.- Oil and gas industry: Used to test the contact resistance of electrical equipment in oil and gas extraction and processing, to ensure the safety and reliability of the system.- Laboratory and research institutions: Used to test the contact resistance of electrical materials and components, to evaluate their performance and reliability.Product specification Measuring range:0-1999.9 μΩ Resolution:0.1 μΩMeasuring current:DC 100A, 200A, 400A, 600A for choiceMeasuring precision:0.5 %RGD+0.05%FSPower supply:AC220V±10% 50HzDisplay:LCDData storage:Save 100 groups dataData connection:RS232 computer interfaceEnvironment temperature:-10 oC- +40 oCRelative humidity:<80%Size and weight:340*280* 210mm,10kg
