Abstract
The utility model discloses an airborne microbe sampler with a self-calibration device. The airborne microbe sampler comprises the calibration device and a sampling device, wherein the calibration device is mounted on the sampling device and includes a mass flow calibration module, and the sampling device includes a temperature measuring module, an air pressure measuring module, a flow measuring module, input equipment, a microprocessor unit, a display module and a fan module. The calibration device and the sampling device work at the same time to automatically calibrate the flow of the sampler; the flow is automatically converted into the actual inlet flow through the temperature measuring module and the air pressure measuring module, so as to eliminate the bias among sampling flows in different operating environments; and accurate flow measurement and control as well as instrument calibration can be realized through a mass flow device, so as to meet the requirements for low cost and high accuracy.
Description
Technical field
The utility model relates to a kind of aerial bacterioplankton sampling thief, is specifically related to a kind of aerial bacterioplankton sampling thief with self-calibrating device.
Background technology
Usually gather air sample with borne bacteria sampler in pharmaceutical industry, foodstuffs industry, medicine inspecting institute, health and epidemic prevention, hospital and other public place, cultivate detection, determine the Air quality situation.At present, borne bacteria sampler has a variety of on market, but it is exactly that self can't calibrate that these products all have a common defective, and domestic metrological service also can't be to its direct calibration, when needing calibration, then adopt special-purpose calibrator that it is calibrated indirectly, and the calibrator of this special use mainly is by a kind of magnetic levitation impeller under meter, what sampling thief was finished is the flow calibration of normal conditions condition, can not truly reflect the flow of the actual air intake of sampling thief; In addition, existing borne bacteria sampler is not with temperature and barometric surveying, and along with the variation of Working environment, accurately stable maintenance is at 100L/mi n for sampling thief actual entry flow, and on-the-spot use is extremely inconvenient.
Summary of the invention
The purpose of this utility model is the deficiency at existing borne bacteria sampler existence, the borne bacteria sampler of the band self-checking device of provide a kind of low cost, being convenient to operate.
For finishing above-mentioned purpose, the technical solution adopted in the utility model is: a kind of aerial bacterioplankton sampling thief with self-calibrating device comprises: calibrating installation and sampling apparatus, calibrating installation is installed on the sampling apparatus, described calibrating installation comprises the mass rate calibration module, described sampling apparatus comprises temperature-measuring module, the barometric surveying module, the flow measurement module, input unit, microprocessor unit, display module, blower fan module, described mass rate calibration module, temperature-measuring module, the barometric surveying module, the flow measurement module, input unit is connected with the microprocessor unit input terminus, image data is flowed to microprocessor unit, described microprocessor unit output terminal and display module, blower fan module, the mass rate calibration module is connected, and transmits result.
The beneficial effects of the utility model: 1, when sampling thief need be calibrated, calibrating installation and sampling apparatus were worked simultaneously, and the flow of sampling thief can be realized automatic calibration; 2, sampling apparatus temperature inside measurement module and air pressure measurement module are converted to flow the actual entry flow automatically, eliminate the deviation of the actual entry sampling flow that different environments for use cause; 3, calibrating installation adopts precision higher quality flow apparatus, realizes accurate flow measuring and controlling and instrument calibration, and currently available products has been realized low cost, high-precision requirement relatively.
