尺寸變化率測定儀主要用于塑料、化工及其它領域，可對被測試驗樣品進行尺寸變化率測量，觀察樣品的狀態，也可用于干燥、固化、烘烤及消毒等。

尺寸變化率測定儀溫度系統采用微電腦智能數字技術制造，具有工業PID自整定和四位雙LED窗顯示功能，控溫精度高、抗力強，并且操作非常方便。箱體采用優質冷軋板，表面靜電粉末噴涂，涂層堅硬牢固，防銹能力強。工作室為優質鋼板，圓角造型、流暢、光滑極易清潔。箱體與工作室之間填充超細*隔熱材料，具有良好的保溫性能，有效保證箱內溫度的穩定準確和對使用環境的影響。箱門觀察窗為雙層鋼化玻璃結構，能夠清晰觀察箱內加熱的物品，又有良好的隔熱效果。箱內設計有合理的熱風循環信道，使箱內溫度分布更加均勻、溫度上升更快；該儀器裝有可調節的出風管，可以調節箱內進出空氣量。如箱內排出的氣體有異味或有毒，出風管能方便的另接管道將氣體排至地點。

主要技術參數

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.
