HI 9564 and HI 9565 are two new portable
thermo-hygrometers designed to provide excellent performance in harsh
environments and poorly lit areas.
A microchip built into the RH probe, HI 70602,
can store calibration data. When the probe is connected to another hygrometer,
the microchip transfers the stored calibration data and eliminates the need to
recalibrate the instrument.
Both instruments feature auto-off after 20
minutes of inactivity, temperature readings in Celsius and Fahrenheit, and
on-line help to indicate anomalies and direct procedures.
In addition to RH and temperature, HI 9565 will
display the dew point with the press of a button. The dew point indicates the
presence of water vapor in the air at a given temperature. With this feature
HI 9565 permits useful and rapid environmental monitoring where a controlled
microclimate is necessary, like greenhouses, museums, clean rooms and
HI 9565 is supplied with HI 70602 RH probe, battery, blue protective case and
