A sampling fluid analytic conduit is also provided in the sampling probe and has a sampling fluid analytic conduit inlet opening spaced upstream from the sampling fluid exhaust conduit outlet opening, downstream from the sampling fluid exhaust conduit inlet opening, and from the wall of the sampling fluid exhaust conduit. A wash conduit can also be provided. Methods for sampling are also disclosed.

A non-water-cooled high temperature aerosol quantitative dilution sampling probe includes a dilution gas tube, a gas mixing tube, a sampling nozzle and a three-way shunt tube, in which the dilution gas tube is used for introducing a dilution gas, and forms, together with a gas mixing tube coaxially fitted therein, an annular passage for transporting the dilution gas; and the sampling nozzle is composed of an injection hole, an outer nozzle and an inner nozzle, and an annular gas flow gap formed between the inner nozzle and the gas mixing tube accelerates the flow of the dilution gas, and forms a negative pressure around the inner nozzle, thereby achieving the purpose of sucking the sample gas by the outer nozzle and mixing it with the dilution gas.

A protective tube, in particular for sealed introduction into a process space having a flow directed in a direction, having a hollow body, which is closed at its lower end, an opening at its upper end for introducing a temperature sensor; and at its upper end has a contour for sealing to a process space. The hollow body is cylindrical inwardly, an outer contour of the hollow body tapers toward the closed lower end, and at least in sections, at least one helix structure is arranged on the outer contour and/or at least in sections, at least one helix structure is arranged in the outer contour. A gas sample collector for introduction into a process space is also provided.

A suction particle detection system having a wall or ceiling feed-through (100) for fluidically connecting a pipe or hose end (200) to a test environment (300), the wall or ceiling feedthrough (100) comprising a line portion (110), which has a first line end (111) for fluidically connecting to the pipe or hose end (200) of the suction particle detection system and a second line end (112) arranged opposite the first line end (111), wherein the second line end (112) is formed with a suction opening (113), having a fastening means (120) for fixing the wall or ceiling feedthrough (100) within a feedthrough opening (320) of a wall-like or ceiling-like room structure (310), and having a flange-like collar portion (114), which extends starting from the second line end (112) in the radial direction, the fastening means (120) having one or more deflectable springs (121).

A gas-detectable mobile power device is disclosed and includes a main body, a gas detection module, a driving and controlling board, a power module and a microprocessor. The main body includes a ventilation opening, a connection port and an accommodation chamber. The ventilation opening is in communication with the accommodation chamber. The gas detection module and the driving and controlling board are disposed within the accommodation chamber. The gas detection module, the power module and the microprocessor are fixed on and electrically connected to the driving and controlling board. The power module is capable of storing an electric energy and outputting the electric energy outwardly. The microprocessor enables the gas detection module to detect and operate. The microprocessor converts the detection information of the gas detection module into a detection data, which is stored and transmitted to the mobile device or an external device.

A gas detecting module is disclosed. A gas-inlet concave and a gas-outlet concave are formed on a sidewall of a base. A gas-inlet-groove region and a gas-outlet-groove region are formed on a surface of the base. The gas-inlet concave is in communication with a gas-inlet groove of the gas-inlet-groove region, and the gas-outlet concave is in communication a gas-outlet groove of the gas-outlet-groove region. The gas-inlet-groove region and the gas-outlet-groove region are covered by a thin film to achieve the effectiveness of laterally inhaling and discharging out gas relative to the gas detecting module.
