Equipment Introduction

1. Device introduction:

用于检验及验证样品在高低温或湿热交变环境下,其电性能,物理性能的符合性;适用于航空航天、电工电子,家用电器,通讯通信,汽车,新能源,军工等行业;可执行高温贮储,低温贮储,高温高湿,湿热交变等多项气候环境测试。

2. 设备特点 :

2.1. 标准的符合性:可执行“95℃&95%RH”高温高湿,“25℃&20%RH”低温低湿的测试;并做到测试过程中不产生凝露与水滴。同时可实现“温度线性上升或下降”状况下同步实现“湿度的线性斜率上升与下降”温湿度双斜率精密控制; 

2.2 安全节能性:采用电子膨胀阀伺服控制冷媒流量的节流技术,达至降低压缩机制冷功率约20%且同时减少制热出力约30%之节能目的;单次低温无故障连续运行≧2400小时;整机运行寿命达100000小时以上,安规性能通过欧盟CE安规检测认证。
