Indlela yokulinganisa ubushushu obuphantsi kwesikhenkcisi

Vula i-ultra low low freezer, xa iqondo lokushisa langaphakathi lizinzile, khetha i-thermometer elinganisiweyo enokulinganisa i-80 degrees.Vula ucango lwesikhenkcezisi sobushushu obuphantsi kakhulu, sinokubona ngokucacileyo ibhloko ye-aluminiyam emva kwesikhenkcisi kwaye kukho umngxuma phantsi kwebhloko ye-aluminiyam, emva koko ubeke i-sensor ye-thermometer kwibhloko ye-aluminiyam emngxunyeni, kwaye ujonge ubushushu kwi-thermometer. kunye neqondo lobushushu kumboniso wesikhenkcisi sobushushu obuphantsi kakhulu.Ukuba umahluko ungaphakathi kwe-1 idigri, akuyomfuneko ukulinganisa ubushushu bomboniso wefriji.
