Product information "HI9564 Thermohygrometers with Temperature and Relative Humidity measurement"
BEPS and low battery warning
HI 9564 is a portable thermohygrometer designed to provide peak performance in harsh environments.
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 9564 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.
HI 9564 is supplied with HI 70602 relative humidity probe, battery and instructions.
