Cold and thermal shock test chambers, also known as cold and hot shock test chambers, are important equipment used in various industries to test the durability and reliability of materials and products under extreme temperature changes. These chambers are designed to rapidly convert test specimens between high and low temperatures, simulating the harsh environmental conditions that products may encounter during use or transport. In this blog, we will explore the functions and features of shock test chambers and how to operate test samples in them. 1. Ring Instruments HYTS series of three-compartment high and low temperature impact test chamber, the main structure is composed of three zones (high-temperature zone, low-temperature zone, test area), high-temperature zone that is the production and storage of high temperature, low-temperature zone that is the production and storage of low-temperature, the test area is to provide customers with the space volume of the product placement. 2. Function. (1) rapid temperature conversion: one of the main functions of the thermal shock test chamber is to quickly and accurately convert the test sample between hot and cold temperatures. This simulates the rapid temperature changes that a product may experience in a real application. (2) Temperature Uniformity: Thermal shock test chambers are equipped with systems that ensure uniform temperature distribution within the test chamber, thus ensuring consistent and accurate test results. (3) Safety Features: These chambers are designed with safety in mind, with features such as overheat protection, an emergency stop button and an automatic shut-off device to ensure the safety of the operator and prevent damage to the test specimen. 3. Special functions (1) Programmable Control Panel: The thermal shock tester is equipped with an advanced control panel that allows the operator to program and customise temperature cycles, dwell times and other test parameters.

The xenon lamp weathering test chamber uses a xenon lamp as a light source, which can simulate and enhance the environment of light, heat, air, temperature, humidity and rainfall. It is suitable for the artificial climate aging test of vulcanised rubber under the specified test conditions, in order to quickly obtain test results approximating atmospheric aging, which is used to evaluate the material's weathering resistance. A sample of vulcanised rubber is placed in the environment of a xenon lamp weathering tester to accelerate the ageing of the vulcanised rubber. By observing changes in the appearance and properties of the specimen, the performance of vulcanised rubber is evaluated to approximate its resistance to natural weathering. So what are the structure and construction of such a test equipment? The following is an example of a xenon lamp weathering tester from "Huan Yi Instruments" to explain. Xenon lamp weathering test chamber structure: 1. The centre of the test box installed xenon lamp light source, the box has a drum installed specimen rack, with xenon lamp power, temperature, humidity, water spray cycle and other indicators and self-control devices, thousands of wet-bulb temperature automatic recorder and timer, the box has a control of the circulating air regulator, used to regulate the temperature of the blackboard and the discharge of ozone inside the box. 2. Xenon lamp is a test light source, the wavelength of its spectrum from 270nm below the short-wave ultraviolet region, the visible spectrum by the expansion of the infrared region. Xenon lamp radiation should be filtered to filter out the shorter ultraviolet light waves, and as far as possible to filter out infrared light waves, so that the spectrum to reach the surface of the specimen is very close to the spectrum of sunlight. 3. Xenon lamps and filters should be replaced periodically according to the technical requirements of the product.
