Function comparison between rapid rate temperature chamber and high low temperature chamber
Definition of rapid rate temperature chamber: suitable for electrical, electronic, instruments and meters, food, parts and materials in the environment of rapid temperature change storage, transportation, use of adaptability test.
Definition of high and low temperature alternating test chamber: suitable for electrical, electronic, instruments and meters, food, parts and materials in high and low temperature environment storage, use of adaptability test.
Similarity: Both specifications, temperature range, temperature uniformity, control accuracy are the same, and the material of both is the same, the inner wall is made of SUS304 stainless steel.The outer chamber is made of cold rolled steel plate electrostatic spray.The basic components are also basically the same.
Differences: the rise and cooling rate requirements are different.The rapid rate temperature chamber has a relatively fast requirement for the lifting and cooling rate, while the lifting and cooling rate of the high and low temperature test chamber is relatively much smaller.
High and low temperature chamber -- heating: about 2.0~3.0℃ per minute on average
Temperature drop: 0.7~1.2℃ per minute on average
Rapid rate temperature chamber -- temperature rise: average per minute about 3.0~10.0℃ selection
Temperature drop: about 1.5~10.0℃ per minute on average
Some of the heating and cooling rate is very fast equipment, because it is necessary to use a semi-enclosed machine overlapping water-cooled compressor unit, and sometimes liquid nitrogen auxiliary cooling, compared with the ordinary high-low temperature chamber is much more complex.To achieve a rapid rate of rise and cooling, its manufacturing costs are higher, power consumption is large, the price is much higher than the ordinary high and low temperature achamber.
