尺寸变化率测定仪主要用于塑料、化工及其它领域，可对被测试验样品进行尺寸变化率测量，观察样品的状态，也可用于干燥、固化、烘烤及消毒等。

尺寸变化率测定仪温度系统采用微电脑智能数字技术制造，具有工业PID自整定和四位双LED窗显示功能，控温精度高、抗干扰能力强，并且操作非常方便。箱体采用优质冷轧板，表面静电粉末喷涂，涂层坚硬牢固，防锈能力强。工作室为优质钢板，圆角造型、流畅、光滑极易清洁。箱体与工作室之间填充超细玻璃棉隔热材料，具有良好的保温性能，有效保证箱内温度的稳定准确和对使用环境的影响。箱门观察窗为双层钢化玻璃结构，能够清晰观察箱内加热的物品，又有良好的隔热效果。箱内设计有合理的热风循环信道，使箱内温度分布更加均匀、温度上升更快；该仪器装有可调节的出风管，可以调节箱内进出空气量。如箱内排出的气体有异味或有毒，出风管能方便的另接管道将气体排至地点。

主要技术参数

Measuring instrument for the size change rate is mainly used for plastic, chemical and other fields, for the testing sample size change rate measurement, observation of the state of the sample, but also can be used for drying, curing, curing and sterilization etc..

Temperature measuring meter manufacturing system using microcomputer inligent digitaltechnology dimension change rate, with industrial PID and four pairs of self-tuning LED windowdisplay function, high precision, strong anti-interference ability, and the operation is veryconvenient. The box is made of high quality cold-rolled sheet, the surface electrostatic powder spraying, the coat is hard and firm, anti rust capability. The chamber is made of high qualitysteel plate, round shape, smooth, smooth and easy to clean. Superfine glass wool insulationmaterial is filled between the box body and the studio, has good thermal insulation performance,effectively guarantee the accuracy and stability of the temperature inside the impact on environment. The observation window on the door is made of double-layer tempered glass, canclearly observe the material heated in the oven, and has good thermal insulation effect. Boxdesign reasonable hot air circulation channel, the inside temperature distribution is more uniform, the temperature rises faster; the instrument equipped with adjustable air tube, can adjust the import and the amount of air box. As the gas ejected from the oven has odor or poison, wind other pipe can be easily connected to the gas discharge to the designated place.
