Dwyer Instruments THI2-10 Installation And Operating Instructions

The THI2-10 Digital Remote Sensing Thermohygrometer accurately takes
humidity, temperature, dew point and wet bulb temperatures inside of ducts and hard
to reach areas. English and metric engineering units as well as the type of
measurement displayed can be easily selected using the push buttons. The push
buttons also allow the user to freeze the current reading or retrieve the minimum and
maximum readings. A large backlit LCD digital dual display allows the user to see both
the temperature and humidity simultaneously and a low battery indicator shows the
user when to change batteries. For hands free operation, the thermohygrometer can
be mounted on a tripod. All units include 4 AAA batteries and a hard carrying case for
safe
