The invention relates to an air negative ion sensor and a measuring method. The air negative ion sensor comprises a collector with a cylindrical structure and a heating dehumidification module; one end of the collector is an air inlet, and the other end of the collector is an air outlet; the cylindrical structure comprises a metal outer cylinder serving as a polarization electrode and a solid metal rod serving as an induction electrode; the heating dehumidification module is arranged at the end, close to the air inlet, of the metal outer cylinder. On the basis of an existing capacitive suctionmethod for measurement, the heating dehumidification module is additionally arranged in structure, so that the temperature of structural components in a whole air path is kept higher than that of outside air, the situation that an actual measurement value is affected due to high-humidity air which is condensed after entering the air path is avoided, and therefore, a measurement error rate is reduced, and the measurement accuracy is improved.
Description
technical field [0001] The invention relates to the technical field of air monitoring, in particular to an air negative ion sensor and a measuring method. Background technique [0002] As one of the important members of active oxygen, air negative oxygen ions have the functions of sterilization, dust reduction, clean air, improvement of immunity, and adjustment of functional balance. They have a very important impact on human life activities and have important health care functions. Air The concentration of negative oxygen ions is also a major indicator of air quality. [0003] At present, the measurement of negative air ions is mainly for the observation, forecast and research of the concentration of atmospheric negative ions (especially small particle size ions), which are mainly used in environmental meteorology, ecological meteorology, tourism meteorology, etc. Through the establishment of the negative ion monitoring network, from the perspective of ecological meteorolo...
