Temperature grade:
According to the liquefaction temperature of different gases at atmospheric pressure, they are generally divided into six temperature grades
Level 1:0- -46℃
Level 2: -47- -60℃
Level 3: -61- -70℃
Level 4: -70- -101℃
Level 5: -102- -196℃
Level 6: Below -253℃
-29℃- -101℃ is called low temperature, bellow -101℃ is called ultra-low temperatures.
