HI-9564 is a portable thermo-hygrometer designed to measure temperature and Relative Humidity (RH). To ensure maximum protection against the effects of humidity and condensation, the instruments are housed in a rugged, water-resistant casing. The temperature and RH probe is a “smart probe” which consists of a factory calibrated electronic sensor which requires no user calibration. The “Smart probe” will work with any Hanna meter without the need to recalibrate as the electronic sensor tracks the performance and stores the calibration history directly onto the probe.
