This device is capable of accurately measuring relative humidity, dew point temperature,
wet bulb temperature, and dry bulb temperature of a HVACR system. The psychrometer
displays these readings on an easy-to-view OLED screen. They work alone or wirelessly
send information to a JB Industries' DM4-W Wireless Digital Manifold, an IOS smart

General Safety
Use caution when taking temperature and humidity measurements. Pipes, tubes, and
other components of HVACR equipment can be very hot (or very cold). Skin can easily be
burned or frostbitten if these components are touched. Use adequate personal protective
equipment when servicing these systems.
