Details of BPH-250S humid and hot test chamber:
Scope of application
BPH-250S constant temperature and humidity test chamber equipment simulates the environment of high, low temperature and high and low temperature cycles, and is suitable for high temperature, low temperature, high and low temperature multi-gradation of electrical and electronic, other products, parts, materials and various electronic components And the performance and storage suitability under temperature cycling conditions can also be used to test the ability of the sample to withstand certain corrosion.
Box structure characteristics
The constant temperature and humidity test box is made of CNC machine tools, which is beautiful in appearance and easy to operate.
The inner tank of the box is made of 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 constant temperature and humidity test box is placed in a large area window with lighting to keep the box bright, and the built-in tempered glass inside the heating body is used to clearly observe the conditions in 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 left side of the cabinet is equipped with a test hole with a diameter of 50mm as a standard , 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。 Constant temperature and humidity test box adopts PID fuzzy temperature control instrument, stable performance , high accuracy, simple operation , and optional micro printer.
Refrigeration and air circulation system
组 采用法国原装 进口 “泰康”全封闭压缩机。 The constant temperature and humidity test box refrigeration unit adopts the "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.
