Abstract
A kind of formaldehyde examination device, whether the concentration for detecting formaldehyde is exceeded, is made of volumetric standard and detection lug, and the volumetric standard includes back box and lid.The back box leaves seal groove, the lid has the sealing strip being used cooperatively with seal groove.The sealing strip material is silica gel, one kind in rubber.The lid leaves jack, for placing the detection lug.Detection device making is simple, raw material is cheap and easily-available, so low manufacture cost, testing result may be utilized.
Description
Technical field
The present invention relates to a kind of gas-detecting device, more particularly to a kind of formaldehyde examination device.
Background technology
Formaldehyde was determined as 1 class carcinogenic substance, people's Long Term Contact suction 12mg/m in 20063Drowsiness, powerless, head can be caused
Bitterly, finger tremble, hypopsia；People sucks 20 ~ 70mg/m for a long time3Can cause loss of appetite, weight loss, it is powerless, headache,
Insomnia.Residenter house content of formaldehyde will be less than 0.12mg/m3, so the content of formaldehyde in monitoring of environmental is very significant.
Concentration of formaldehyde test in indoor environment and air of workplace uses impingement, i.e., is extracted using sampling pump
The air sample of certain volume passes through formaldehyde absorption bottle, uses chemical colorimetric to be analyzed afterwards.This method needs professional people
Member, professional equipment carry out analysis test, and time-consuming relatively long, costly, are not suitable for ordinary people family and use.
The content of the invention
Based on this, it is necessary to provide a kind of formaldehyde examination device simple, whether quick test concentration of formaldehyde is exceeded.
A kind of formaldehyde examination device, whether the concentration for detecting formaldehyde is exceeded, and the formaldehyde examination device includes standard
Container and detection lug, the volumetric standard include back box and lid, and lid is covered seals assembling in back box, and lid leaves jack,
For placing the detection lug, the detection lug includes substrate and hand-held rod.
Further, the back box leaves seal groove, the lid has the sealing strip being used cooperatively with seal groove.
Further, the sealing strip material is one kind in silica gel, rubber.
The beneficial effects of the utility model are：Detection device making is simple, raw material is cheap and easily-available, so low manufacture cost.
Brief description of the drawings
Fig. 1 is the structure of the detecting device schematic diagram of an embodiment.
Fig. 2 is the detection lug schematic diagram of an embodiment.
Embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention
Embodiment be described in detail.Many details are elaborated in the following description in order to fully understand this hair

Similar improvement is done in the case of running counter to intension of the present invention, therefore the present invention is not limited to the specific embodiments disclosed below.
As shown in Figure 1, volumetric standard includes back box 100 and lid 200, back box leaves seal groove 110, the seal groove and lid
The sealing strip 210 of son is used cooperatively, and completes sealing, and lid leaves jack 220, for placing detection lug 300, and covers jack
220。
As shown in Fig. 2, the detection lug further includes substrate 310 and hand-held rod 320.
A kind of formaldehyde examination device, whether the concentration for detecting formaldehyde is exceeded, and formaldehyde examination device includes volumetric standard
And detection lug, the volumetric standard include back box and lid, lid is covered seals assembling in back box, and lid leaves jack, is used for
The detection lug is placed, the detection lug includes substrate and hand-held rod.
Further, the back box leaves seal groove, the lid has the sealing strip being used cooperatively with seal groove.
Further, the sealing strip material is one kind in silica gel, rubber.
Further illustrated below in conjunction with specific embodiment.
Embodiment 1
Formaldehyde examination device, whether the concentration for detecting formaldehyde is exceeded, and formaldehyde examination device includes volumetric standard and inspection
Piece is surveyed, the volumetric standard includes back box and lid, and lid is covered seals assembling in back box, and lid leaves jack, for placing
The detection lug, the detection lug include substrate and hand-held rod.
Further, the back box leaves seal groove, the lid has the sealing strip being used cooperatively with seal groove.
Further, the sealing strip material is one kind in silica gel, rubber.
The beneficial effects of the utility model are：Detection device making is simple, raw material is cheap and easily-available, so low manufacture cost.
Embodiment described above only expresses the several embodiments of the present invention, its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
