Measures a wide indoor temperature range from 32°F to 122°F (0°C to 50°C).
Measures an outdoor temperature range of -4°F to 140°F (-20°C to 60°C) using alkaline batteries or -40°F to 140°F (-40°C to 60°C) using lithium batteries.
Barometric pressure readings, history, and forecast.
The wireless remote sensor transmits up to 200ft.

8″ Universal Automatic Make-Up Air Damper with Pressure Sensor Kit.
Interlocked make-up air damper systems meet IRC Code requirements for make-up air with range hoods over 400 CFM.
Interlocked make-up air systems avoid wasted energy associated with barometric solutions and do not let unwanted air into the home during heating or cooling activities so air pressure is equalized for a well-balanced environment.
Fresh air wall caps are required for use with Make-Up Air Dampers.
Interlocked make-up air dampers provide outside air when required to keep the air in the home fresher by allowing the range hood to operate at optimum levels.
Balance indoor air pressure by providing interlocked make-up air without requiring a direct wire connection between the range hood and the damper.
Instead a sensor is attached to the exhaust duct to detect if the range hood is operating.
Slave dampers (MD6S, MD8S or MD10S) are interlocked to the main automatic or universal make-up air damper and open in unison for synchronized operation..
