The Dwyer KS0503 Horizontal Reversible Temperature Strip, 86 - 140°F provides a constant and reliable indication of current temperature status. The reversible, reusable strips change color when temperatures increase or decrease, and are constructed with non-toxic encapsulated thermochromic liquid crystals. The temperature strips are self-adhesive, and have an accuracy of ±2°F (±1°C). These reversible strips are resistant to oils, water and steam-ideal for monitoring pipes, food storage areas, transportation climate control, equipment monitoring, pharmaceutical or medical applications.
