Alternating high and low temperature impact three box test chamber

Alternating high and low temperature impact three box test chamberSuitable for the physical changes of electrical, electronic, and mechanical components, automation parts, communication products or components, chemical materials, hardware and plastics, LED, LCD optoelectronics, photovoltaics, lighting, semiconductor ceramics, and polymer materials. It tests the rapid and repeated resistance of materials to cold and hot temperatures, as well as the chemical changes or physical damage that occur when industrial products are in an environment of thermal expansion and contraction. It can confirm the quality of industrial products, from precision ICs to heavy machinery components, and can serve as a basis or reference for improving the quality of many products in the industrial industry. In order to assess the adaptability of the product or evaluate the behavior of the tested product. It is an important testing method throughout the entire process of new product development, prototype testing, and product qualification testing.

Alternating high and low temperature impact three box test chamberBasic operating procedures and precautions

1. Operation steps

Preparation stage: Ensure stable laboratory power supply, check if the equipment wires are damaged, and place the equipment on a flat surface, away from heat and water sources.

Turn on the device: Turn on the power switch and wait for the device to warm up, so that the temperature and humidity inside the box reach the preset value.

Place the sample: Place the sample on the sample rack, keeping a certain distance from the box wall to ensure air circulation.

Set temperature: Set high temperature, low temperature, and temperature change time on the control panel according to experimental requirements.

Start experiment: After pressing the start button, closely monitor the operating status of the equipment.

Post experiment processing: After turning off the equipment, take out the sample and wear protective gloves to avoid burns or frostbite.

Cleaning equipment: Clean the internal dust and debris after each use, and regularly check the integrity of the wiring and components.

2. Key precautions

Safety warning: Strictly abide by safety regulations, avoid accidents such as electric shock and burns, and stop operation immediately in case of abnormal situations.

Temperature control: Regularly calibrate equipment to ensure temperature accuracy and avoid drastic temperature changes affecting sample performance.

Record keeping: Detailed records of the operation process, sample information, and results of each experiment.

*Business training: Operators must possess professional knowledge and skills, and are not allowed to change experimental parameters without authorization.
