Adopting fully automatic computer control and advanced compressor electronic refrigeration technology, it is completely unaffected by environmental temperature changes, ensuring that the temperature difference between the inner and outer cylinders of the instrument meets national standards. Can work continuously for 24 hours., Automatically adjust the temperature of the inner and outer cylinders, reduce the cooling correction factor, and make the measurement results more accurate. Adopting a unique refrigeration and temperature control system, the temperature rise and fall during the experimental process is zero. Ensuring the stability and accuracy of the experimental results. The unique semiconductor refrigeration type water circulation system can customize the cooling capacity according to the previous heat generation, balance the circulating water system, keep the water temperature relatively constant, reduce environmental impact, and perfectly solve the common problem of the external bucket water temperature exceeding the room temperature by 1.5 ℃ after 4-5 consecutive experiments of the calorimeter in the past (the national standard requires that the external bucket temperature and room temperature cannot exceed 1.5 ℃ during the experimental process), making the experimental results more accurate and truly leveraging the advantages of the fully automatic calorimeter
