Honeywell 00920A3 Indoor Outdoor Clock Thermometer

Product Description

The HONEYWELL 00920A3 is a 13.5-inch metal-cased combination clock, thermometer, and hygrometer designed for both indoor and outdoor installation. The unit runs on a standard quartz clock movement and measures ambient temperature and relative humidity alongside timekeeping. The metal case with pewter finish and glass lens gives it durability suited for covered outdoor mounting points such as patios, garages, and equipment rooms. Installation requires one AA battery. This type of instrument is commonly used by HVAC technicians, facility maintenance staff, and building service professionals to monitor environmental conditions at a glance without electronic infrastructure.

The 00920A3 is suited for residential and light commercial applications where a simple, at-a-glance temperature and humidity reference is needed. Typical install locations include covered outdoor walls, garages, server rooms, storage areas, and mechanical rooms. Because it operates independently of any wiring or control system, it functions as a standalone reference instrument rather than a sensor integrated into a building automation or HVAC control loop.
