Temperature Indicator Sign: IceAlert™ Indicator Sign

This circular dial sign indicates the potential for icy conditions by changing from reflective silver to reflective blue. This temperature detecting sign reports the temperature by automatically beginning to change color at 36 °F (2 °C) and becoming fully bright blue at 32 °F (0 °C). When the temperature rises, the sign will automatically return to silver. It is encased in a clear-faced plastic case with holes for wall or post mounting (tamper-proof fasteners included). This self-contained sign does not require batteries or any electronics. POST NOT INCLUDED.

This circular sign is available in two sizes, 6" diameter and 9" diameter (15.2 or 22.9 cm).

For maximum effectiveness, pair this dial with our Freezing Temperature When Blue (item # 11070) or Icy Conditions When Blue (item # 11071) sign. BOTH SOLD SEPARATELY.
