Description

TECHNICAL FIELD

[0001] The utility model relates to oil fume concentration test technical field, specifically is an oil fume particulate matter concentration tester. BACKGROUND

[0002] The oil fume particulate matter concentration tester is mainly based on optical principle and particulate matter measurement technology, and determines the particulate matter concentration in the oil fume by detecting the scattering or absorption of light. When light passes through the particulate matter in the air, the light will interact with the particulate matter, changing its propagation path. These effects can be scattering or absorption of light. The instrument can infer the concentration of particulate matter by measuring the change in scattering or absorption intensity of light in the sample. The oil fume particulate matter concentration tester can be used for detecting the oil fume in the kitchen chimney and testing the particulate matter concentration of the flue gas discharged by the factory.

[0003] Currently, when the oil fume particulate matter concentration tester detects the particulate matter concentration of the internal flue gas of the chimney and the exhaust pipe, the detection rod is usually inserted into the internal detection port of the exhaust pipe. The probe at the end of the detection rod can collect and analyze the flue gas to complete the detection of the flue gas. The diameter of some exhaust pipes is smaller than the length of the detection rod. When detecting, the detection rod will protrude out of the exhaust pipe, and a large part of the detection rod will be in a suspended state. The tester at the end of the detection rod needs to support and protect the detection rod from bending and deforming in real time, so as to achieve the protection effect. The detection rod is not provided with an auxiliary supporting mechanism. If the flue gas collection time is long, not only the user's work difficulty is increased, but also the user's support on the tester is released or pressed downward, which may cause the detection rod to deform, affecting the pulling out or reuse of the detection rod.

[0004] Therefore, in view of the above problems, an oil fume detection instrument capable of supporting collection needs to be designed. UTILITY MODEL CONTENTS
