Our high-quality mercury-free thermometer measures the temperature of your garden greenhouse or outside garden to within a degree. The thermometer features a dual scale, allowing you to see the temperature in Celsius and Fahrenheit without having to do any complicated conversion equations. The thermometer also displays the maximum and minimum temperature of the day on the digital display below the current temperature measurement.
In most European Union countries mercury is banned completely in all products, therefore it has become necessary to introduce mecury-free theremomters. However the original design of the max/min thermometer still uses and applies mercury, due to it's properties of being liquid at room temperature.
