Carrying Case

The HHF42 is an economical
solution for any air flow application,
such as, air conveyors, flow hoods,
balancing, fans/motors/blowers,
furnace velocities, refrigeration
cases, paint spray booths and
environmental testing. The portable
HHF42 provides fast, accurate
readings with digital readability and
the convenience of a remote probe.
The combination of hot wire and
standard thermistor delivers rapid
and precise measurements even at
low air velocities. The HHF42
microprocessor circuit assures the
maximum possible accuracy and
provides special functions and
features.
