Abstract
The present invention provides an air detector comprising a detector body, the detector body is in a shape of a normal triangular prism, the center of the detector body is provided with a triangular prism cavity as a sensor air chamber of the detector body, and an air inlet and an air discharge port of the sensor air chamber are respectively provided with a glass fiber microporous filter net. The air detector is novel in structure and easy to carry, the contact area of a passage of the sensor air chamber and air is large, the contact time is longer, measurement is more accurate, by arrangement of the microporous glass fiber filter nets at the air inlet and the air discharge port, interference of ethanol, carbon monoxide, and the like can be effectively eliminated, and the measurement accuracy of formaldehyde and PM2.5 is higher.
Description
Technical field
The invention belongs to air detection technical field, especially relate to a kind of air detection instrument.
Background technology
Portable gas detector is widely used in petrochemical complex, fire-fighting, urban construction, the industries such as mine.Generally be used for detecting: inflammable gas or toxic gas or choke damp.Portable gas detector is divided into pump suction type and diffusion type according to its principle, detects gaseous species be divided into single gas detecting instrument and compound gas detector according to it.Diffusion type instrument is placed directly in test environment and detects gas.Usually need people for carrying detection, majority is applicable to mine workman and carries, or the enterable environment of people.
Sensor is most important parts in portable gas detector, and whether instrument precisely depends on the sensitivity level of sensor; Different gas to be measured is generally with the sensor of fixing kind.
The problems such as it is single that but existing air detection instrument exists structure mostly, and accuracy of detection is not high.
Summary of the invention
In view of this, the present invention is intended to propose a kind of air detection instrument, to solve prior art Problems existing.
For achieving the above object, technical scheme of the present invention is achieved in that
A kind of air detection instrument, comprise detector body, described detector body is regular triangular prism shape, and the center forms the sensor air chamber of a triangular prism-shaped cavity as described detector main body, and the air intake opening of sensor air chamber and exhaust ports are equipped with glass fibre porous screen pack.
Further, described glass fibre porous screen pack is double-decker.
Further, described air detection instrument body comprises power module, also comprises control treatment module and coupled respectively air detection module, print module, display module; Described control treatment module controls described air detection module and detects air, controls described print module and prints air detection result, controls described display module display air detection result.
Further, the air detection module of the air detection instrument body of described regular triangular prism shape, print module and display module lay respectively on three different faces.
Further, two adjacent side of the air detection instrument body of described regular triangular prism shape are provided with the groove structure being beneficial to grasping.
Relative to prior art, air detection instrument of the present invention has following advantage:
Air detection instrument novel structure of the present invention, be convenient for carrying, and its sensor air chamber passage and air contact surfaces amass larger, duration of contact is longer, measure more accurate, be provided with glass fibre porous screen pack in exit, gas access simultaneously, effectively discharge the interference of ethanol, carbon monoxide etc., make the measuring accuracy of formaldehyde and PM2.5 higher.
