Hanna Instruments HI9564 Thermohygrometer with Calibration Data Logging Probe
The HI9564 Thermohygrometer is used to measure temperature and relative humidity in greenhouses, museums, clean rooms, laboratories, and other areas where a controlled microclimate is necessary. The thermometer measures temperature from 0 to 60 degrees C (32 to 140 degrees F), with an accuracy of + or - 0.5 degrees C and + or - 1 degree F. The hygrometer measures humidity from 20 to 95% relative humidity (RH), with an accuracy of + or - 3% RH from 50 to 85% RH and + or - 4% RH outside this range. The thermohygrometer has an HI70602 calibration probe, which has a built-in microchip that stores calibration data. The unit has an auto-off function that shuts the power off after 20 minutes of non-use. The HI9564 is used by museum curation specialists, greenhouse owners, and laboratory scientists to monitor temperature and humidity.

Digital thermometers are instruments used to measure the temperature of air, liquids, or surfaces electronically. They may measure temperature in Celsius, Fahrenheit, or both. Most digital thermometers use thermistors, which are small electronic resistors. Thermistors are made out of metals that conduct electricity within a certain range and become more conductive the warmer they get. A microcontroller inside the thermometer measures this electrical conductivity and converts it to a temperature, which is displayed on an LCD. Digital thermometers are used in a wide range of applications, including in laboratory settings, food service and storage, and in doctors' offices and hospitals.
