What the AcuRite 315 is and who it suits

The AcuRite 315 is a digital window thermometer built for homeowners who want a simple view of indoor and outdoor temperature. Its reversible display and weather-resistant construction let it work on either side of a window pane. The bold LCD shows current readings plus daily high and low records. It mounts with a repositionable suction cup or a hang hole.

The specification that decides fit

The reversible design is the single detail that determines whether this unit suits your window. It allows the screen to be read from inside while the sensor sits outside, or the reverse, without extra hardware. If your window glass is textured, tinted too dark for the suction cup to hold, or you need a wireless remote sensor, this model will not meet the need.

Capacity and headroom

The thermometer comfortably handles everyday household monitoring, giving instant current temperature and a day-long min/max memory. It runs out when you need trend logging, multiple zones, or alerts sent to a phone. The single included suction cup limits mounting to one smooth glass surface at a time.
