Thermal anemometer testo 405 Flow velocity measuring instrument with temperature m/s measurement Volume flow measurement up to 99990 m/h C Extendable telescope up to 300 mm Display illumination testo 405 is a thermal anemometer. It allows the precise The testo 405 measures especially accurately in the range measurement of air flow velocity, volume flow and from 0 and 2 m/s. Low air flow velocities such as at temperature. With the extendable telescope (up to 300 mm), draughty windows, for example, can thus be localized testo 405 is particularly suited for measuring the flow exactly and measured extremely accurately. velocity in ducts. Thanks to the attachment included in The display can be rotated into different positions. This delivery, the telescope can be optimally positioned in a enables optimum readout of the measurement values. duct. www.testo.comtesto-405-P02 12.07.2013 07:33 Seite 2 testo 405 We measure it.
