Description
Technical field
the present invention relates to a kind of formaldehyde tester, particularly relate to a kind of portable formaldehyde tester.
Background technology
along with the development of modern industrial society, house fitting-up is more and more general.Due to the formaldehyde pollution air that the paint of new furniture and interior decoration discharges, the formaldehyde poisoning caused by formaldehyde pollution, skin disease, breathing problem etc. happen occasionally, and therefore effectively detect that the concentration of formaldehyde in air is very necessary; But formaldehyde examination paper in the market coordinates formaldehyde test agent to be sell separately, detecting step is loaded down with trivial details, use very inconvenient, and the test duration can not be effectively controlled, cause test result error larger, relevant clarifier product more can not be coordinated to use, be not easy to effectively be promoted.
formaldehyde is one of main room atmosphere pollution in modern day life, and on China's toxic chemical list, formaldehyde is in second.Under normal temperature, formaldehyde is a kind of colourless, gas excitatory.Formaldehyde in air will produce harm to the respiratory tract of humans and animals when exceeding certain content; The formaldehyde of high concentration has damaging effect to nervous system, immune system and liver.Suspicious teratogenesis, carcinogen is defined as by the World Health Organization (WHO) (WHO).Current existing formaldehyde tester is by a formaldehyde collection pipe, a reaction tube, and a spectrophotometer composition, formaldehyde collection, chromogenic reaction and light absorption value are measured and carried out respectively.The formaldehyde tester of this method exploitation can carry out field monitoring, and result is sensitive, accurately and reliably.But, need to divide and manually add reagent several times, collect, react and measure and manually carry out, operate too loaded down with trivial details.Because manufacture according to national standard exploitation, be suitable for functional department so compare, or corresponding professional institution uses.Another shortcoming of this instrument is formaldehyde collection and measures the sample carrying out step by step can only realizing according to schedule collecting in the air of certain volume, then measures, is unfavorable for adjusting according to the needs of different spaces the volume collecting sample flexibly.In fact, the effect of the formaldehyde tester used in daily life is just an oneself to gaseous contamination degree in room and is understood, do not need especially accurate measurement result, therefore, need to propose that a kind of structure is more simple, operation formaldehyde tester more easily.
at present, in formaldehyde method of testing, at the scene in test, spectrophotometric method limit by the operating conditions such as water-bath or the concentrated sulphuric acid; Though vapor-phase chromatography is more accurate but be only applicable in lab analysis, and expensive equipment, not easily apply.Along with the raising day by day of the living standard of people, people need a kind of simple, sensitive, portable formaldehyde tester fast and accurately.
Summary of the invention
the object of this invention is to provide a kind of easy to use, conveniently carry with, can the effectively and accurate portable formaldehyde tester of one of the advantage such as content of formaldehyde in the inherent unit air of sensing chamber.
in order to realize object of the present invention, the present invention is realized by following technological means: a kind of portable formaldehyde tester, comprises housing, lever; It is characterized in that: described housing bottom connects lever; Described housing is provided with display and stand by lamp, and described lever is provided with control knob; Described case top is provided with air-vent; Described enclosure interior is provided with control circuit board, testing sensor and blower fan; Described lever inside is provided with accumulator; Described accumulator connection control circuit board, described control circuit board is connecting test sensor respectively, blower fan, stand by lamp, display, control knob.
described control circuit board is provided with charging module, power module, CPU main control module, storer, blower fan driver module, sensor acquisition module, alarm module, display module; Described charging module connects accumulator and power module, and described power module connects CPU main control module, and described CPU main control module is connecting communication module respectively, storer, blower fan driver module, sensor acquisition module, alarm module, display module; Described display module connects display; Described alarm module connects stand by lamp; Described blower fan driver module connecting fan; Described sensor acquisition module connecting test sensor.
described lever is provided with charging inlet; Described charging inlet connects charging module.
be provided with flowmeter between described induced draft fan and air-vent, between described induced draft fan and testing sensor, be provided with filtrator; Described flowmeter connection control circuit board.
principle of work of the present invention:
in the present invention, by air suction inlet, room air is sucked, by air is introduced inner testing sensor after reaction, test structure is sent to the control circuit board of inside of the present invention by sensor, related data is shown after data analysis over the display by display module by control circuit board, and judges whether to drive stand by lamp to send alarm by alarm module according to data.
in the present invention, structure is simple, and be convenient for carrying, blower fan is provided with flowmeter, and convenient metering sucks the flow of air, and simultaneously inner filtration unit facilitates other gases in filtered air, according to the content of formaldehyde in air in measuring unit accurately.
beneficial effect of the present invention:
the present invention has easy to use, conveniently carries with, can the effectively and accurate advantage such as content of formaldehyde in the inherent unit air of sensing chamber.
