The maintenance secret of low-temperature constant temperature box:

When shutting down after completing low-temperature operation, it is necessary to set the temperature condition to 60 ℃ and perform drying treatment for about half an hour to avoid affecting the measurement time of the next operating condition or icing phenomenon.

2. If a heating sample is placed inside the box, please use an external power supply for the sample power control, and do not directly use the local power supply.

3. The radiator (condenser) of the freezer should be regularly maintained and kept clean.

If you want to observe the changes inside the box during the test, you can turn on the indoor light switch and learn about the internal changes through the window.

Before conducting a humidity test, the first thing to check is whether there is water in the water tank. The water level in the water tank should not be too high or too low.

6. The inlet pipe of the humidification bucket must discharge the remaining air * to prevent water from entering.

7. It is prohibited to test explosive, flammable, and highly corrosive substances.
