功能特点：

Functional Characteristics:
1、采用数字式温度调节器调控温度、灵敏、准确、操作方便。

1. A digital temperature adjuster is used for regulating and controlling the temperature, realizing sensitivity, accuracy and convenience in operation.

2、工作室底部设有进风孔，箱顶装有排气阀门 ，冷空气从箱底进入，由箱顶排出并设有风力搅拌，使低温场更均匀。

1. Air inlets are arranged at the bottom of an operating room and exhaust valves are positioned thereon, so that the cold air enters from the bottom and is exhausted from the top. No wind stirring is involved, making the low temperature field more uniform.

3、A型产品工作室由薄钢板制成，喷涂耐热涂层，箱门装有玻璃观察窗，便于观察工作室内情况。

1. The operating room of the A product is made of sheet steel and sprayed with a heat resistant coating. The door of the operating room is provided with a glass viewing window so as to view the conditions inside.

4、AD型产品工作室采用优质不锈钢制成，并加装钢化玻璃门，便于观察试样，采用PID数字控温，减小温度波动。

The operating room of the AD product is made of superior stainless steel and further provided with a tempered glass door for viewing the test sample conveniently. PID digital temperature control is adopted hereby to reduce the temperature fluctuation.
