Compared with household refrigerators and commercial refrigerators, medical refrigerators require high precision temperature control, temperature fluctuations in the box value is small, high uniformity, more than the use of electronic controllers, open the door after the temperature fluctuations are small, the temperature recovers quickly, with a perfect alarm system, and the configuration of the temperature recorder records the temperature operation in order to check the temperature of the core Kang 2 ~ 8 ° C medical refrigerator temperature is accurate to 0.1 ° C.
