1、 Purpose:

This product is suitable for measuring the dimensional change rate of various plastic pipes and plastic profiles after heating, conducting state tests after heating, and measuring longitudinal shrinkage rate. It can also be used as a substitute for ovens.

2、 Instrument features:

The constant temperature box uses a side heating forced hot air circulation heating system, and the blower system adopts a multi blade centrifugal fan, which has the characteristics of large air volume, low noise, uniform working room temperature, stable temperature field, and avoiding direct radiation of heat sources. The control system is all centralized in the control room on the left side of the box, making inspection and maintenance convenient. The temperature control system adopts a digital display regulator for automatic temperature control, with simple and intuitive operation, small temperature fluctuations, and over temperature protection function. This product has good insulation performance and is safe and reliable to use.
