Programmable constant temperature and humidity testing machine, environmental reliability testing equipment, wide temperature range, precise humidity control

Description :

  The constant temperature and humidity test chamber is a core detection equipment used to simulate complex climate environments, mainly solving the verification problem of temperature and humidity sensitivity in product research and development, production, and quality inspection. This device constructs stable and reproducible temperature and humidity conditions in a closed chamber through the precise collaborative work of four major systems: heating, cooling, humidification, and dehumidification. It is widely used in fields such as electronics and electrical engineering, automotive components, aerospace, and new materials, aiming to evaluate the performance stability, weather resistance, and expected service life of products or materials under extreme or changing climate conditions. It is a key tool to ensure that product quality meets strict standards at home and abroad.

  This constant temperature and humidity test chamber usually has a wide temperature and humidity control range, with a typical temperature range covering -70 ℃ to+150 ℃ and a humidity range controlled between 20% RH and 98% RH, which can meet the vast majority of industrial testing needs. The equipment is designed in accordance with mainstream domestic and international testing standards such as GB/T 2423, IEC 60068, MIL-STD-810, ensuring the authority and comparability of test data. The box is made of high-quality stainless steel liner and high-strength cold-rolled steel plate shell, combined with multi-layer vacuum insulation materials, effectively reducing heat loss and preventing condensation. The control system often uses programmable logic controllers (PLCs) combined with color touch screens, supporting multi-stage program settings, real-time data recording, and curve display, with intuitive operation and high accuracy.

  When selecting a constant temperature and humidity test chamber, it is important to consider the size, heat generation, and required rate of temperature and humidity change of the test sample. For large volume or high heat generating samples, a model with a larger volume and sufficient redundant cooling power should be selected to avoid temperature failure due to excessive heat load. If the test requires rapid temperature changes, it is necessary to confirm whether the equipment is equipped with linear heating and cooling functions or auxiliary refrigeration systems. In addition, it is necessary to distinguish between the ordinary type and the high, low temperature, and low humidity type, with the latter being suitable for testing scenarios with strict requirements for low humidity environments. Compared with simple high-temperature or low-temperature chambers, the constant temperature and humidity test chamber adds a humidity control module, which is more complex in structure and requires relatively higher maintenance. When selecting, it should be matched according to the specific terms of the actual testing standards.

  When installing a constant temperature and humidity test chamber, it is necessary to ensure that there is sufficient heat dissipation space around the equipment. It is usually recommended to reserve a distance of more than 60cm on the back and both sides, and maintain good indoor ventilation. The recommended ambient temperature is between 5 ℃ and 30 ℃. In daily use, it is necessary to regularly check the water level in the water tank and use purified or deionized water to prevent scaling and blockage of the humidifier. The condenser fins need to be regularly cleaned of dust to maintain cooling efficiency. When the machine is shut down for a long time, the box should be dried and the power should be cut off. Common malfunctions such as abnormal humidity display are often caused by the hardening or dehydration of wet bulb gauze, and require timely replacement of gauze or replenishment of water; If the temperature fluctuates greatly, it may involve air duct blockage or sensor failure, which needs to be calibrated and maintained by professionals to ensure continuous and stable testing capabilities.
