Hanna HI 8064 Hygrometer

Includes used probe, as shown in pictures

With a simple rotary switch measuring both relative humidity and temperature, the Hanna HI 8064 ranks among the easiest thermohygrometers to operate. Just turn the dial from off to RH% for relative humidity in % from 10 to 95% or °C for temperature in Celsius, and the large LCD will show the appropriate measured value in seconds.

The probe handle contains the amplification circuitry and ensures an accurate & linear reading throughout the range. The probe tip is perforated to allow air circulation and thus guarantee a fast response time. To measure humidity electronically, a thin film polymer capacitance is used. The probe handle is made of tough ABS material to withstand the wear and tear of everyday use.

Weighing less than a pound, with battery life of one hundred hours and a response time of less than half a minute, HI 8064 is ideal for use in schools, libraries, museums and horticulture.
