The HHF81 anemometer can measure air flow,
humidity, temperature and light. The built-in
microprocessor circuit assures excellent performance
and accuracy. The HHF81 can track the maximum
and minimum values along with current readings. The
HHF81 and HHF82 display the flowrate in your choice
of knots, meters per second, kilometers per hour,
miles per hour, feet per minute.
The HHF81 and HHF82 rely upon a low-friction ball
bearing mounted wheel design to provide high
accuracy at high and low air velocity. The impeller
provides excellent accuracy (±3 to 4%) and the ability
to measure the slightest breeze (0.3 m/s). For
temperature readings, the HHF81 has an internal
thermistor or is compatible with any Type K
thermocouple with SMP Male connector, accurate to
±1°C + 1% of reading. The humidity sensor measures
to 95% relative using a high precision thin-film
capacitance sensor with fast response to humidity
changes. The Light measurement utilizes an exclusive
photo diode and color correction filter light sensor.
