Great Lakes now offers Upsite Technologies temperature strips; with a self-adhesive
backing, the temperature strip can easily attach to most surfaces within your enclosure.
Displaying both Fahrenheit (in increments of 2°) and Celsius(in increments of °1) readings,
the temperature strip is accurate to within +/- 1°C. Actual temperature is denoted when
liquid crystals in the temperature strip display green. When brown and blue appear on the
strip, the actual temperature is between these two numbers. Temperatures will fall into one
of three ranges as indicated by the colors at the bottom of the strip.
