Temperature Rise Tester for Electrical Components – Measures Heat Generation in Plugs, Sockets, Connectors, and More

📌 Temperature Rise Tester Overview

The Temperature Rise Tester is a temperature rise testing device developed in accordance with Chinese national standards and relevant standards for electrical accessories. It is primarily used to evaluate the surface heating of electrical accessories (such as plugs, power plug wires, and sockets) under load current conditions. This equipment is widely used in electrical accessory testing, industrial quality control, and product certification fields.

This tester features an advanced design with multi-point temperature measurement capability. It has a compact and aesthetically pleasing appearance, small footprint, reasonable internal layout, high measurement accuracy, and is easy to operate and maintain. It is an ideal tool for temperature rise performance testing of plugs and sockets.

The working principle of the Temperature Rise Tester involves short-circuiting the positive and negative terminals of a plug or socket, connecting the tail to the current output terminal, and powering on the current. After setting the test current and duration according to the standard, the temperature rise of the pins and conductor joints of the plug or socket is measured under a specified current load and time. The test results are then compared against national or industry standards to assess whether the product meets safety and performance requirements.

This device is a critical instrument for plug and socket manufacturers, electrical product laboratories, and quality inspection departments to conduct electrical temperature rise tests and quality control. It is applicable throughout the entire process of R&D, production, and final inspection.

The Temperature Rise Tester not only supports thermal performance evaluation for a variety of plug, socket, and connector specifications, but also can be integrated with temperature recording systems, load current adjustment modules, and other auxiliary devices to meet diverse testing standards and requirements. With high stability and strong expandability, it is well-suited for long-term batch testing and validation in new product development. It serves as an essential technical means for evaluating the thermal safety performance of electrical products.
