        | Hand-held psychrometer type Operating range 0 to +60 ¡ÆC / 10 to 100 % r.H. |  | FNA846   Hand-held 
psychrometer type
 
   
    |  ¡Ü Operating range 0 
      to +60 ¡ÆC / 10 to 100 % r.H.
 ¡Ü Available 
      values :
 dry temperature, relative humidity, dew point, mixture ratio,humid temperature, 
      partial vapour pressure
 
 ¢Ñ For precision measuring operations the current
 atmospheric pressure can be entered in ALMEMO¢ç
 devices and the measured value will then be corrected
 automatically.
