Temperature Decals Include LCD

The reversible LCD temperature decals consists of six model ranges that monitor temperatures from -30°C to 100°C in 5°C increments. On a single decal there are seven liquid-crystal indicator windows that change color from black to brown when the monitored temperature is slightly below an indicator window's rated temperature. When a window turns green, it indicates that the surface temperature is ±1°C of its rated temperature. As surface temperature increases slightly above a window's rating, it turns blue and eventually turns black as the surface temperature increases further. The colors are visible in the reverse sequence as the surface cools. Price is $1.60 each/100.
