        | Probe tube with heated miniature thermistor for flow measurement |  | FV A645 TH3 Thermoanemometer 
Type
 
  
    |  
 ¡Ü Probe 
      tube with heated miniature thermistor for flow
 measurement and highly precise Ni10 temperature sensor for temperature compensation.
 ¡Ü Evaluation 
      electronics are located in a separate module
 housing.
 ¡Ü 
      Measurement modules can be directly plugged 
      onto the
 measuring instruments.
 ¡Ü 
      Particularly suitable for low wind velocities, e.g. for
 draught measurements at work places.
 
 ¢Ñ When attaching the measuring module 
      other input
 sockets will be blocked. If the blocked input sockets need
 to be used or if the module can be directly installed at
 the measuring location, an extension cable ZA 9060-VKx
 (maximum length 5m) must be used.
