Details of BPH-250B high and low temperature test chamber:
Scope of application
BPH-250B high and low temperature test chamber equipment is an environment that simulates high, low temperature and high and low temperature cycles. It is suitable for electric and electronic, other products, parts, materials and various electronic components to perform high, low and high temperature gradients, and The performance and suitability for storage under cyclic changes can also be used to test the ability of the sample to withstand certain corrosion.
Box structure characteristics
The high and low temperature test box is made of CNC machine tools, which has a beautiful appearance and easy operation.
The inner tank of the high and low temperature test box adopts imported high-grade stainless steel (SUS304) mirror panel, and the outer tank of the box is sprayed with A3 steel plate, which increases the appearance and cleanliness.
面积 视窗附照明灯保持箱内明亮，且利用发热体内嵌式钢化玻璃，随时清晰的观测箱内状况。 The high and low temperature test box is placed in a large area window with an illumination lamp to keep the box bright, and the tempered glass embedded in the heating body is used to clearly observe the condition of the box at any time.
标 配直径50mm的测试孔，可供外接测试电源线或信号线使用。 The 50mm diameter test hole is standard on the left side of the high and low temperature test box , which can be used for external test power lines or signal lines.
PID 模糊 温度控制仪表， 性能稳定精度高， 操作简单 ， 可选配 微型 打印机。 The high and low temperature test box adopts PID fuzzy temperature control instrument, which has stable performance , high accuracy and simple operation , and can be equipped with a miniature printer.
Refrigeration and air circulation system
组 采用法国原装 进口 “泰康”全封闭压缩机。 The refrigeration unit adopts "Taikang" hermetic compressor imported from France .
离心 式送风机强力送风循环，避免任何死角，可使测试区域内温度分布均匀。 The centrifugal blower is used for strong air circulation to avoid any dead angles, which can make the temperature distribution in the test area uniform.
， 可提高效率， 降 低故障率。 The heating and cooling systems are completely independent , which can improve efficiency and reduce failure rate.
