Honeywell 00315A1 Digital Window Thermometer

Product Description

The HONEYWELL 00315A1 is a suction-mount digital thermometer designed for indoor or outdoor temperature monitoring. It attaches to any window via a reversible suction cup, allowing placement on either the interior or exterior glass surface. The unit displays current temperature across a range of -4 degrees F to 158 degrees F and logs daily minimum and maximum readings for quick reference. Powered by an included CR2032 lithium button cell battery, the thermometer features a low battery indicator to prevent unmonitored gaps in readings. The weather-resistant housing holds up to exterior exposure without degrading the display or casing.

This thermometer is suited for residential and light commercial applications where a quick, tool-free window installation is needed. Facilities technicians, HVAC service pros, and property managers use units like this to verify ambient conditions at a glance during service calls or to monitor temperature in unconditioned spaces such as garages, storage areas, or server rooms. No wiring is required, and no penetrations are made in the building envelope during installation.

Installation Notes

For outdoor placement, position the unit away from direct sunlight to avoid artificially elevated readings. Confirm battery is seated correctly before mounting to avoid removing the unit immediately after installation.
