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.
