The HI9564 is a rugged, portable thermohygrometer designed to provide high accuracy temperature and relative humidity (RH) readings under harsh environmental and industrial conditions. The meter offers a variety of features including a HOLD button, Battery Error Prevention System (BEPS), auto-off, and a variety of display codes to help the user understand the functionality and potential errors of the instrument.
The HI9564 has selectable temperature and RH modes. The measurement mode can easily be switched at the press of the RANGE button. Both temperature and RH are measured with the HI706023 probe which features an internal temperature sensor and a built-in microchip that stores calibration data.
Features at-a-glance
Durable Humidity Probe – The HI706023 is a thin-film polymer capacitive (TFPC) sensor that accurately measures relative humidity and temperature. Encased in a durable ABS housing, the probe features a perforated cap to allow for rapid and stable measurements. A built-in microchip allows for calibration data to be stored in the sensor as opposed to the meter. If the probe is connected to another hygrometer, the microchip transfers the stored calibration data and eliminates the need to recalibrate the instrument.
℃/℉ Readout – Temperature is displayed in ℃ or ℉. A slide switch on the HI9564 allows the user to change the temperature readout unit.
HOLD Button – A simple press of the HOLD button allows the user to freeze a measurement on the LCD screen. Even in HOLD mode, the meter channels can still be scrolled through to show the status of the meter when HOLD was pressed.
Auto-off Feature – The meter can be set to automatically turn off after 8 or 60 minutes.
Battery Error Prevention System (BEPS) – The Battery Error Prevention System detects when the batteries become too weak to ensure reliable measurements.
