生化培养箱对温度控制精度要求很高， 一般要求其温度控制误差不大于±０－５ ℃。影响生化培养箱控温性能的因素很多， 在设计和维护中均需予以认真考虑。本文就生化培养箱控温系统中测温元件的选择、安装位置、加热功率的大小及配备方式等对其温控精度的影响进行了试验研究， 提出了提高温度控制性能的相关措施 Biochemical incubator on the temperature control accuracy is very high, the general requirements of its temperature control error is not greater than ± 0-5 ℃. Many factors affect the temperature control performance of biochemical incubator, both in the design and maintenance needs to be seriously considered. In this paper, temperature control system in biochemical incubator temperature control system components selection, installation location, the size of heating power and equipped with its temperature control accuracy of the experimental study carried out to raise the temperature control performance of the measures
