The hand-held hot air device, preferably for the local heating of thermoplastic materials, with a housing that forms a wand-shaped handle part with air inlet openings, and with an air guidance tube that protrudes from the handle part and radially delimits an air canal, with an electric heating element contained in the air guidance tube and an electric motor with a fan wheel contained in the handle part, and with an electronic control system arranged inside the handle part with one semiconductor power switch each arranged upstream of both the heating element and the electric motor, and with a display screen and an operating device for the hand-held hot air device arranged on the outside of the handle part. The electronic control system is implemented as microprocessor control system, the display screen as an electronic digital display, and the operating device as a digital operating device, with the digital operating device comprising a single universal operating element that is movable in at least two directions relative to the handle part for the purpose of switching the hand-held hot air device on and/or off and for determining control data of the microprocessor control system.

A flow sensor for measuring the flow of a gaseous or liquid medium with a sensor housing in which, between an inlet channel and an outlet channel, a flow channel extends that comprises a main channel and a measuring channel that is arranged parallel to the main channel. At least one main channel choke point is arranged in the main channel, and the measuring channel comprises a sensor element for measuring the flow. A measuring channel choke point in the measuring channel on the inlet and/or the outlet side, is arranged with the main channel choke point having at least one passage and the measuring channel choke point having a passage, both passages being of identical shape and extending parallel to each other in the flow direction.

An antimicrobial composition, including a synergistic combination of three or more agents as an active ingredient. Each of the three or more potentiating agents can be selected from the following types of compounds: sequestering agents, carbohydrates and carbohydrate derivatives, terpenes/terpenoids, amines and amine derivatives, plant-derived oils, sulfonates, phenols, fatty acids, dibenzofuran derivatives, organo isothiocyanates, quaternary ammonium compounds, peroxides and peroxide donors, and macrolide polyenes. At least two of the three or more potentiating agents are not of the same type of compound. The antimicrobial composition can have strong antimicrobial efficacy in control of microorganisms having resistance to currently used antimicrobials.
