Summary
Low-temperature environmental testing is an important testing method for detecting the low-temperature tolerance, structural stability and performance reliability of materials, components and samples. It is widely used in multiple fields such as material research and development, electronic manufacturing, chemical testing and scientific research experiments. The DW-80 vertical low-temperature test chamber (80L), as a miniaturized and high-precision low-temperature testing device, features a compact and reasonable structure, precise temperature control performance, and stable refrigeration effect. It is suitable for low-temperature tests, freezing preservation, and low-temperature aging detection of various medium and small-sized samples, filling the market gap of small and precision low-temperature testing equipment. It has become the preferred equipment for small and medium-sized enterprises and laboratories of scientific research institutions and universities.
The core features of this equipment are precise temperature control, rapid cooling and good temperature uniformity, which can meet the strict requirements of low-temperature test standards. The equipment is equipped with an imported fully enclosed compressor refrigeration unit, combined with an optimized single-stage refrigeration cycle system. It features high refrigeration efficiency, stable cooling speed, and can quickly reach the preset low-temperature working conditions. Meanwhile, the equipment operates with reasonable energy consumption and low noise, making it suitable for long-term stable indoor operation. Relying on the microcomputer intelligent digital display control system, the temperature regulation accuracy of the equipment can reach 0.1℃, and the temperature control error is controlled within an extremely small range. The temperature inside the box is uniform and stable, with no local temperature difference deviation. It can provide a uniform and constant low-temperature test environment for the samples, ensuring the accuracy and repeatability of the low-temperature test data.
The structural design is in line with the practical needs of the laboratory, taking into account space utilization, observation convenience and usage safety. The equipment adopts a vertical compact structure with a standard volume of 80L, which is moderate and does not occupy too much space in the laboratory. It is suitable for the placement requirements of medium and small-sized laboratories and R&D workstations. Meanwhile, the vertical structure makes it convenient to take and place samples, and the operation is convenient and efficient. The box body is integrally processed by CNC machine tools, with a neat and grand appearance. The outer shell is made of high-quality steel plate and treated with plastic spraying, which is wear-resistant, scratch-resistant, corrosion-resistant and easy to clean, making it suitable for long-term use in laboratories. The inner liner of the box is made of SUS304 stainless steel, with a smooth inner wall without dead corners. It is resistant to low temperatures and corrosion, and will not deform or rust due to long-term low-temperature operation, effectively extending the service life of the equipment. The equipment is equipped with a three-layer vacuum-coated large observation window, which comes with an embedded lighting device. The test status of the internal samples can be clearly observed without opening the box door. Moreover, the observation window is designed with anti-fog features, eliminating the need for manual defogging. This ensures a clear field of vision throughout the process and does not interfere with the test progress.
The equipment is equipped with a complete protective design and adaptability, operates stably and reliably, and is suitable for various test scenarios. The body is equipped with dedicated test holes, which can be connected to external detection instruments, sensors and other equipment, meeting various dynamic low-temperature detection and data acquisition test requirements, and expanding the test functions of the equipment. The equipment is equipped with an intelligent temperature control protection system, featuring multiple safety mechanisms such as over-temperature warning, overload protection, and power-off protection. When the equipment experiences abnormal temperature or operational overload, it can automatically activate the protection mechanism to avoid the risks of equipment failure and sample damage, ensuring the safety and stability of the testing process. At the same time, the equipment is compatible with 220V conventional household voltage, does not require a dedicated power supply line, is easy to install and debug, and can be put into use immediately after startup, lowering the threshold for equipment to be placed on the ground.
