由河北省石家庄市第一建筑公司科研所研制,河北省冀县起重运输机械厂生产的“WSZK-1型温湿自控器”(简称自控器),是一种用于混凝土试件标准养护室的温湿自动控制装置,已通过省级技术监定。经各单位实际使用表明,控温精度为20C±1℃控湿范围在RH90％以上,节电省水,使混凝土试件在规范要求的温湿范围内得到正确地养护。
Developed by the Scientific Research Institute of the First Construction Company of Shijiazhuang City, Hebei Province, the “WSZK-1 Type Temperature and Humidity Automatic Controller” (abbreviated as Automatic Controller) produced by the Crane Transportation Machinery Plant of Ji County, Hebei Province is a standard maintenance for concrete specimens. The room temperature and humidity automatic control device has passed provincial-level technical supervision. The actual use of each unit shows that the temperature control accuracy is 20C±1°C and the humidity control range is more than 90% RH. It saves electricity and saves water, so that concrete specimens are properly maintained within the temperature and humidity range required by the specifications.
