The maintenance secrets of low temperature and constant temperature test chamber:wJBTextile Testing Instruments, Testing Equipment Manufacturer


1. When you use the machineturn off during low temperature operation When the process is complete, make sure the drying temperature is set to 60°C. Treat it for about half an hour;wJBTextile Testing Instruments, Testing Equipment Manufacturer


In order not to affect the measurement time or the freezing phenomenon of the next working condition. wJBTextile Testing Instruments, Testing Equipment Manufacturer


2. When a heated sample is placed in the box, please use an external power supply to control the power supply of the sample, and do not use the local power supply directly. wJBTextile Testing Instruments, Testing Equipment Manufacturer


3. The cooler (condenser) of the freezer should be regularly maintained and kept clean. wJBTextile Testing Instruments, Testing Equipment Manufacturer


4. If you want to observe the changes in the box during the test, you can turn on the interior light switch and see the changes inside through the window. wJBTextile Testing Instruments, Testing Equipment Manufacturer
