Environmental testing equipment plays a crucial role in modern industrial production and quality control. Among them, programmable thermal shock test chambers are widely used due to their ability to simulate the effects of extreme temperature changes on products. Dongguan Qingsheng Testing Equipment Co., Ltd., as one of the large-scale programmable thermal shock test box manufacturers in South China, is renowned for its honest operation and carefully crafted national thermal shock test boxes. This article will provide a detailed introduction to the characteristics of the QTST-27L programmable thermal shock test chamber produced by Qingsheng Testing Equipment Co., Ltd.
1. Meet multiple national standards:The QTST-27L programmable thermal shock test chamber meets multiple national standards, including GJB150.3-86, GJB150.4-86, and GJB150.5-86, ensuring its application standards in the military and high-end manufacturing fields.
2. Diversified models and sizes:Qingsheng Testing Equipment Co., Ltd. provides various models and sizes of programmable thermal shock test chambers, ranging from QTST-27L to QTST-560L, with different internal and external dimensions to meet the testing needs of different customers.
3. Advanced structure and technology:The QTST-27L programmable thermal shock test chamber is known for its beautiful appearance, reasonable structure, advanced technology, and exquisite material selection. It has simple and convenient operational performance and reliable device performance.
4. Efficient switching of cold and hot air paths:The equipment is divided into three parts: a high-temperature box, a low-temperature box, and a testing box. It adopts a thermal insulation structure and thermal storage and cooling effect. During the experiment, the test object is stationary, and the hot and cold temperatures are introduced into the testing area through the switching of cold and hot air paths to achieve the purpose of cold and hot shock testing.
5. Intelligent controller and operating interface:The controller adopts a large color LCD human-machine touch dialogue LCD human-machine interface controller, which is easy to operate, easy to learn, stable and reliable. Display the complete system operation status, execution, and program setting curves in both Chinese and English.
6. Automation and efficiency:With 96 independent test specifications, the impact time can reach 999 hours and 59 minutes, and the cycle period can be set from 1 to 999 times. It can achieve automatic operation of the refrigeration machine, maximize automation, and reduce the workload of operators.
7. Safety and protective devices:There is a test hole on the left side of the box, which can be used for external power load wiring and testing components. Equipped with the function of a high and low temperature testing machine, a fully automatic, high-precision system circuit, and P.L.C locking processing for any component action.
8. Temperature control and cycle design:Adopting P.I.D automatic calculation control, the temperature control accuracy is high. Advanced scientific air circulation design ensures uniform indoor temperature and avoids any dead corners.
9. Automatic defrosting and air door control:The number of cycles and defrosting times can be set for automatic (manual) defrosting. The air outlet is detected and controlled by the return air outlet sensor. The switching time of the air door mechanism is completed within 10 seconds, and the recovery time of the cold and hot shock temperature is completed within 5 minutes.
10. Efficient refrigeration system:In order to ensure the cooling rate and minimum temperature requirements of the test chamber, this test chamber adopts a binary cascade air-cooled refrigeration system composed of an imported French "Taikang" fully enclosed compressor.
The QTST-27L programmable thermal shock test chamber from Dongguan Qingsheng Testing Equipment Co., Ltd. provides strong testing support for various industries with its excellent performance and reliability. Whether in the military, automotive, electronics, or other fields, Qingsheng's test chambers can meet your stringent requirements for product quality and performance.
