HI 9564 is a new portable thermometer hygrometer designed to provide excellent performance in harsh environments and poorly lit areas.
A microchip built into the RH sensor, HI 70602, 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.
Features auto-off after 20 minutes of inactivity, temperature readings in Celsius and Fahrenheit, and on-line help to indicate anomalies and direct procedures.
