产品描述
高低温一体机它是通过泵浦驱动传热介质(通常为水或油)从装有内置加热器的油箱中到达控温设备，再从控温设备回到油箱。控制器根据温度传感器测量的热流体温度或控温设备内部温度，调节热流体的温度从而调节控温设备的温度。
产品特点
1.全封闭管道设计，采用高效板式换热器，在提供系统热利用率的同时减少对导热液的需求，实现温度的快速上升和下降
2.采用前馈自适应可编程控制器，可以准确控制反应堆物料的温度，并且系统在控制过程中，无超调，无回调
3.最多可存储编写120套程序，每个程序可编写100段，充分保证了在不同材质情况下的温度要求。用户只需要根据不同的物料调出程序，即可实现准确的温度控制，避免了人工操作过程，提高了产品的稳定性。
4. 5.3英寸彩色触摸屏显示和输入；控制系统提供：USB接口，RS232接口，PT100输入接口，故障报警输出接口
5.温度过程控制图可在高分辨率彩色触摸屏上显示，包括油温，设定目标值，反应堆物料控制温度值，便于查询全过程控制。使用USB数据存储接口，只要直接插入USB闪存盘，整个温度控制过程中，数据就可以记录下来。
6，导热油循环管道全封闭设计，无油雾，不吸水，确保实验安全和导电液寿命；
7.具有自我诊断功能；过载继电器和热保护装置等多种安全功能
8.高扬程设计，适合长距离传输介质.
