Specification

HI 9064 and HI 9065 are heavy-duty hygrometers specifically designed for field applications such as HVAC systems.
They are housed in a rugged water-resistant case to provide maximum protection in the field.
The relative humidity probe contains a thin-film polymer sensor, which quickly performs all RH readings to 98% accuracy.
A " HOLD" key will instantly freeze the reading on the LCD.
HI 9065 can also measure temperature with an internal sensor in the RH probe from 0 to 60° C as well as 32 to 140° F scales.
You can also connect a separate temperature probe for gas and liquid measurements ( HI 765 series) .
