产品用途：
盐干湿循环腐蚀试验箱突破了传统盐雾箱的概念，具有通常盐雾腐蚀的功能外，还结合有交变（循环）盐雾试验的功能，提供了腐蚀和丝状腐蚀等试验环境，具备了盐雾、湿热、干燥等试验环境。与传统盐雾箱相比，盐雾、干燥、湿热等循环腐蚀对产品的作用更切合实际，因为产品都是在干湿环境中运输、保存、使用。所以加速腐蚀试验机应更能切合实际地模拟这种环境，并且国外研究亦表明：循环腐蚀相对于腐蚀速率、结构、形态都非常接近于户外腐蚀，与户外腐蚀有着极好的相关性，并列入常用试验范畴，越来越多的汽车行业的试验都要求进行多步聚的将盐雾（NSS、AASS、CASS）、干燥、湿热，结合起来循环。
符合标准：
可按 GB/T10125－1997、NES-M0158;ASTM B117-2002、BS7479：1991 进行中性盐雾试验（NSS）、醋酸盐雾试验（ASS）、铜加速醋酸盐雾试验（CASS）

主要特点：
◆ 整机采用进口CPVC板，内部采用立体补强结构，耐酸碱、耐温永不老化，适用于盐雾、醋酸铜等各种测试规格。
◆ 采用手动/自动加水系统，水位不足时能自动补水，保证试验不中断，并附有水位警示装置。
◆ 精密玻璃喷嘴(PYREX)雾气扩散均匀，并自然落于试验样品，并保证无结晶阻塞。
◆ 温度控制器7寸触摸屏，P.I.D控制，误差±0.1℃。操作简单方便，可任意设定盐雾测试程序。
◆ 喷雾塔附锥型分散器，具导向雾气，调节雾量及均匀落雾量等功能。
◆ 试验室采用蒸气直接加温方式，升温速度快且均匀，减少待机时间，加热管采用商耐腐蚀钛管制成。
◆ 加大型机种试验箱上盖用气缸自动开关，操作容易、安全。
◆ 试验室栅架采用平面分度架，可任意调整角度，四面落雾及受雾方向完全一致，试验片放置数里多。
◆ 实验完成后，具有自动除雾装置，可清晰的观察试验内测试样品。
