Product Description

The HONEYWELL 00782A3 is a wireless digital thermometer designed to display both indoor and outdoor temperatures simultaneously. The system consists of a main receiver unit and a remote sensor that transmits readings wirelessly. The receiver features an easy-to-read digital display and reports temperature in both Fahrenheit and Celsius. The water-resistant outdoor sensor makes this unit suitable for year-round monitoring in residential or light commercial settings. The main unit is powered by 2 AAA batteries, not included. HVAC technicians, building managers, and service professionals use devices like this to verify ambient conditions during system diagnostics and commissioning.

This thermometer is suited for indoor and outdoor temperature monitoring in residential homes, small commercial spaces, and service environments. The wireless design eliminates the need to run sensor wiring between the indoor receiver and the outdoor sensor, simplifying placement. The water-resistant sensor can be mounted on an exterior wall or sheltered outdoor surface. Typical users include HVAC technicians verifying return-air and outdoor ambient temperatures and facility personnel monitoring equipment rooms.
