CE Safety Certification: High and Low Temperature Alternating Test Chamber AT58250SC01008502
1. Device introduction：
The test chamber was used to test and verify the conformity of electrical and physical properties of samples under high temperature, low temperature, and alternating high and low temperature environments; It can conduct multiple climate and environmental tests, including high-temperature storage/operation, low-temperature storage/operation, and high-low temperature cycling; Suitable for industries such as aerospace, electrical and electronic, household appliances, communication, automotive, new energy, military, etc.
2. Device features :
2.1.Accurate and stable: volatility: ≤± 0.3 ℃; Temperature deviation: ≤± 1.0 ℃; Temperature uniformity ≤ 1.0 ℃; Heating rate: 0.05-3.0 ℃/min with linear slope setting; Cooling rate: 0.05-1.5 ℃/min can be set with a linear slope; All performance indicators comply with national standards such as GB2423 and IEC60068, as well as international testing standards。
2.2 Safe and energy-saving：The throttling technology using electronic expansion valves for precise servo control of refrigerant saves 30% energy compared to traditional capillary throttling methods; And it can achieve a single low-temperature fault free continuous operation for 2400 hours; The overall operating life of the machine is over 100000 hours, and its safety performance has passed the EU CE safety inspection and certification (CE certificate: AT58250SC01008502）。
