Abstract

The invention provides a odor tester, a odor testing method and a odor testing device. The odor tester comprises an intelligent control system and a dynamic dilution device, the dynamic dilution device comprises a plurality of olfactory discrimination ports, and each olfactory discrimination port corresponds to a reference gas path and a detected gas path; the intelligent control system generatesa sniffing port selection instruction based on the received test signal, randomly selects one sniffing port from the sniffing ports as a target sniffing port according to the sniffing port selection instruction, and determines the unselected olfactory discrimination port as an air sniffing port, enables the target olfactory discrimination port to discharge the detected malodorous gas to a sniffingperson, enables the air olfactory discrimination port to discharge clean gas to a sniffing person; and after receiving the olfactory discrimination data fed back by each olfactory discriminator, analyzing the olfactory discrimination data to obtain an analysis report. By applying the stink tester provided by the invention, the olfactory discrimination port for discharging the stink gas to be tested and the gas path to be tested can be randomly switched, so that the sniffing personnel can be prevented from being communicated with each other, and the accuracy of sniffing data is improved.

Description

technical field [0001] The invention relates to the technical field of odor detection, in particular to an odor measuring instrument, an odor measuring method and a device. Background technique [0002] Stench is a general term for various odors (odors). According to relevant discussions at home and abroad, stench can be defined as: any gas that can produce unpleasant sensations is generally called stench gas, and is referred to as stench for short. When the peculiar smell in the environment reaches a certain level, it will make people feel unpleasant, and even cause psychological impact and physiological harm to people, which is called stench pollution and belongs to the category of air pollution. [0003] With the rapid economic development and the enhancement of public awareness of environmental protection, odor (odor concentration) indicators have received widespread attention. At present, the domestic odor pollution test is mainly based on the national standard "GB / T14...
