A kind of air detection equipment with dust measuring function in above-mentioned, the port table wall of air-out port described in its structure offers direction along port and is evenly placed with electromagnetic induction heating circle electrified regulation, this air-out port ambient air environment temperature is caused to rise instantaneously, and consider that enter to divide port and air-out port on this apparatus subject inherently exist an obvious difference in height, and air-out port is positioned at the below of air intake port, therefore, above-mentioned enter point port and air-out port because air is formed obvious cross-ventilation, the particle of certain particle size range of carrying in this air-flow can form scattered light with the parallel beam effect emitted by light source, 's receive by the photelectric receiver in direction at a right angle, zoom into umber of pulse per minute through integration to read, the reading (CPM) rectified an instrument with standard method is again in mass concentration (㎎/m
3), thus finally realize dust measuring function.Because cross-ventilation is without the need to passing through mechanical type drainage in said process, therefore this cross-ventilation is relatively milder, and the dust granules in this partial air there will not be the phenomenon of concentrations or excessively dispersion, thus ensure that dust measuring effect.
That conveniently corrects scatter plate arranges angle, ensure the dust measuring accuracy after a long time use of this equipment to the full extent, the switching above-mentioned apparatus subject is also provided with for switching scatter plate and horizontal light beam concrete angle angle value between the two controls handwheel.
As further technological improvement, filter paper in the sealing of above-mentioned air-out port.
Filter paper is set up by the air-out port at this device in above-mentioned further Technological improvement plan, above-mentioned filter paper can be taken off and weigh by the user of this equipment, finally combine the dust content that the gas flow measured calculates gas, compare with the structure originally recorded by light scattering method again, promote dust measuring accuracy further.
A kind of air detection equipment with dust measuring function that the utility model obtains, it is high that it has possessed dust measuring accuracy in actual use, some row advantages of grade easy to use.
