Max Min Thermometer
From: Thermometers and Thermostats : Thermometers & Weatherstations
This Mercury Free Quick ReSet Max/Min Thermometer is easy to use - it records and displays the highest and lowest temperatures reached as well as showing the current temperature.
Displays temperature in both degrees Centigrade and Fahrenheit.
Highest and lowest temperature are recorded by marker pins which are set by the movement of the alcohol columns. The markers will record the highest and lowest temperatures since last reset.
Dimensions: 8" (20cm) long x 2¼" (6cm) wide.
Instructions For Use:
Mount securely to a wall, greenhouse wall or post via the built in hanging hole at the top of the thermometer.
Keep away from direct sources of heat, such as direct sunlight, which could result in a false reading.
To Reset hold the reset button depressed while the markers fall back to the column (if the indices fail to reset, hold button down and gently tap the side of the case).
