Testo 510, abbinato al tubo di Pitot, misura la velocità dell'aria. Per ottenere misure precise, è possibile compensare la densità dell'aria. testo 510 è molto maneggevole, semplice da utilizzare e con dimensioni ridotte. 13. Specifications 13 Specifications Functions and use The testo 510 is a differential pressure measuring instrument. It is normally used to measure small differences in pressure (e.g. to check filter permeability), gas flow pressure measurement, fine draught measurement as well as flow velocity measurement with a Pitot tube. Manual. Follow the prescribed steps exactly. For safety reasons, use only original spare parts from Testo. Any further or additional work must only be carried out by authorised personnel. Testo will otherwise refuse to accept responsibility for the proper functioning of the instrument after repair and for the validity of certifications. The testo 511 is an absolute pressure measuring instrument. It is normally used to measure absolute pressure, e.g. for pressure compensation in velocity measurement in ducts, laboratories and production processes. Further measurement parameters are barometric (surface) pressure (= pressure at sea level) and altitude above sea level.
