阿美特克Ametek冷干体炉JOFRA -125A型|B型的产品介绍
-125是2006年底新推出的冷型干体炉，它的温度可以-90℃，目前是温度，重量轻的干体炉。-125采用了AMETEK的自由活塞制冷技术，冷却压缩机和加热元件结合，使加热和制冷时间大大缩短。机内冷媒使用很少的气体，不使用氟利昂和液体制冷，合法规要求，保护大气环境。它在计量，制药，液化天然气，食品，医院等行业会有适合的应用。
在常温下可以实现-90℃到125℃的温场，可以对低温传感器进行校准。作为目前世界上温度的干体式温度校准仪，125重20公斤，却可以实现快速降温。由于采用了的技术，125的技术指标接近实验室液槽，同时相对于其它带制冷功能的干体式温度校准仪实现了的温度范围跨度。125B还具有各种测试接口，可以直接测量热电阻，热电偶等各种被校传感器的信号，可以在不使用计算机的情况下，对温度传感器实现全自动的校准，并且可以把校准结果上传到计算机。
