Thermometer Dial Max-Min

This bi-metal dial thermometer indicates the maximum and minimum temperatures reached.
The easy to read dial can be reset by rotating the central knob.

Gardeners use max-min thermometers in the greenhouse and the garden to check minimum temperatures during the cold months when frost can be a problem and to check the maximum temperature during the daytime.

It can be wall mounted via the screw holes.

To Use
Turn the central knob clockwise until both red and blue arms are touching the metal pointer. The pointer will then move and record the highest and lowest temperatures.
