In the middle of the application, why don't you just open the door of the environmental test chamber? Programmable high and low temperature box is used to test whether the commodity is heat resistant, ultra-low temperature can be -20C, -40C, -60C, -70C and even lower, high temperature can do 150C. Because the temperature range of the environmental test chamber is wide, so the equipment user must pay attention to a lot when doing experiments:
1, if in the environmental test chamber has been extremely ultra-low temperature detection of - 70 - c, this time the door is open environmental testing, the first cold cyclones will spillover environmental test chamber, if we didn't do your finger touch all security protection environment chamber wall on goods try, will be a short period of time cold, cold location of the muscle fibers and shrink.
In addition, the programmable high and low temperature box is very low temperature, opening the door of the environmental test box is likely to lead to frost in the air conditioning evaporator, harm the temperature reduction rate, and even may lead to the damage of refrigeration compressor and other problems.
2, if programmable high and low temperature box, has carried out the door is open when high temperature of 150 c test environment test, high temperature steam experience in a short period of time through environmental test chamber, if not for protection, are more likely to burn to everyone's face, if by the environmental test chamber has a low point flammable, and is likely to cause fire.
3. If the environmental test box has been carried out in the programmable high and low temperature box, the working pressure and steam in the equipment will be very large. If the door of the environmental test box is opened at this time, there will be high temperature and low temperature steam breaking through the environmental test box, which is very likely to lead to serious consequences for the actual operation and the staff.
Therefore, programmable high and low temperature box operation halfway. Do not open the environmental test box door if it is not necessary to open the door; Otherwise, it will cause adverse effects. The equipment application staff should fully grasp the operation instructions and strictly operate according to the requirements before application.
