各种类型的干燥箱、培养箱、恒温恒湿箱、高低温交变湿热试验箱等控温箱体广泛应用于食品、机械、化工、建筑、医疗等诸多行业。目前,各级计量检定部门校准、检测该类控温箱体的主要依据是JJF1101-2003《环境试验设备温度、湿度校准规范》。在实际工作特别是现场校准、检测过程中,笔者对JJF1101-2003 Various types of oven, incubator, constant temperature and humidity box, high and low temperature alternating hot and humid chamber and other temperature control box is widely used in food, machinery, chemicals, construction, medical and many other industries. At present, the measurement and verification departments at all levels to calibrate and test the main basis for this type of temperature control box is JJF1101-2003 “environmental test equipment temperature and humidity calibration specification.” In the actual work, especially on-site calibration, testing process, the author of JJF1101-2003
