HI9565 Thermohygrometer with Dew Point and Calibration Data Storage in Probe

Product information "HI9565 Thermohygrometer with Dew Point and Calibration Data Storage in Probe"

Backlit LCD
Auto shut-off
HOLD button
BEPS and low battery warning


HI 9565 is a portable thermohygrometer designed to provide peak performance in harsh environments. For poorly lit areas the HI 9565 features a backlit LCD.

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 quick and effective environmental monitoring where a controlled microclimate is necessary, like greenhouses, museums, clean rooms
and laboratories.

This instrument also features a HOLD button to freeze readings on the display for manual recording and BEPS (Battery Error Prevention System) which alerts the user in the event that low battery power could adversely affect readings.

HI 70602 RH probe features a built-in microchip that 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.

HI 9565 features auto-off after 20 minutes of inactivity, temperature readings in Celsius and Fahrenheit, and online help to indicate anomalies and direct procedures.

For dusty environment, please consider HI93640 as it has a sintered cap to protects the sensor from dust.

Order Information:
HI 9565 is supplied with HI 70602 relative humidity probe, battery and instructions.
