No probe change is needed when switching range. The meter is operated through just one rotary knob for all measurements. With a simple rotary switch measuring both relative humidity and temperature, HI 8064 ranks among the easiest thermohygrometers to operate. The probe handle contains the amplification circuitry to ensure an accurate and linear reading throughout the range. The probe tip is perforated to allow air circulation and thus guarantee a fast response time.
Calibration is simple and can be carried out through trimmers on the probe.
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 a hundred hours and a response time of less than half a minute, HI 8064 is ideal for use in schools, libraries, museums, horticulture and routine measurements.
