The HHF801 is an economical 
solution for any air flow 
application, such as, air 
conditioning and heating 
systems, wind speeds, 
balancing, and environmental 
testing. The portable HHF801 
provides fast, accurate 
readings with digital 
readability and the 
convenience of a remote 
probe. The combination 
of a vane and standard 
thermistor delivers rapid and 
precise measurements. The 
microprocessor circuit assures 
the maximum possible accuracy 
and provides special functions 
and features.
