The dew point meter is an instrument that directly measures the dew point temperature. A mirror is cooled in the sample's wet air until the moment on the mirror surface reveals the drop, and the average mirror temperature is measured. It has high humidity measurement accuracy, but requires a highly polished mirror surface, a high precision temperature control system, and a highly sensitive dew drop optical detection system. The pipe that inhales the sample air must be kept clean during use, otherwise impurities in the pipe will absorb or release moisture causing measurement errors. Dew point meter In order to get high quality products or equipment to operate normally, many industries such as petrochemical, electric power, electronics, aerospace, metallurgy, textile and so on have higher and higher requirements for humidity measurement. Therefore, humidity measurement has gradually become a Emerging technology areas.
