Description
The HI9564 thermohygrometer delivers precise measurements of temperature (-10 to 60°C / 14 to 140°F) and relative humidity (0–100% RH) with high resolution and accuracy. The HI706023 probe, a thin-film polymer capacitive (TFPC) sensor, features a perforated cap for fast, stable readings and a built-in microchip storing calibration data. When connected to another compatible hygrometer, the probe transfers its calibration automatically, eliminating the need for recalibration. Users can easily switch between temperature and RH modes and choose °C or °F readouts using the slide switch.
Designed for convenience and reliability, the HI9564 includes a HOLD button to freeze readings, a user-selectable auto-off to conserve battery, and a Battery Error Prevention System (BEPS) to prevent weak batteries from affecting measurements. Lightweight and compact, it can be comfortably handheld or placed on a table. The meter runs on three AAA batteries, offering approximately 10,000 hours of continuous use, and operates reliably in 0–60°C with up to 98% non-condensing RH.
