为配合建筑工程冬施测温,北京市建筑工程研究所四室根据建筑业的特点,研究了便携式建筑电子测温仪。该仪器采用数字显示,读数清晰操作简便,测温准确。其测温范围为—40～+120℃,精度为±0.5℃。主机在—20～+50℃环境中可正常工作,低于—20℃时可加棉罩正常工作。并有夜间读数照明功能。为避免混凝土受冻,在混凝
In order to cooperate with the temperature measurement of construction projects in winter, the Beijing Institute of Building Engineering studied the portable building electronic thermometer based on the characteristics of the construction industry. The instrument uses a digital display, clear reading operation is simple, accurate temperature measurement. Its temperature range is -40 ~ +120 °C, with an accuracy of ± 0.5 °C. The host can work normally in a temperature range of -20 to +50°C, and can add a cotton cover to work normally if it is lower than -20°C. And night reading lighting function. To avoid concrete freezing, in the coagulation
