maximum minimum thermometer
Considering the very low price, both accuracy and quality are surprisingly good. I had an identical one in a greenhouse which lasted for years (and even then I just sold the house, with the greenhouse plus thermometer included.) It coped with cold, heat, water and sun exposure with no problems.
