This item is everything I hoped for in a greenhouse, or indeed a house, thermometer. The casing is plastic, well-made and put together. No handbook, because there is no need - this thermometer works exactly as you'd expect.
It shows the temperature now. You press 'clear' each morning, or whenever, to be rid of the existing figures for maximum and minimum. Next morning you can see how high and how low the temperature rose. The thermometer is a fast responder, so if you have delicate plants and need to check urgently, this is the right one for you.
You can choose centrigrade or farenheight, and the thermometer converts to either in a second. Great for a whole family of gardeners!
This item is user-friendly for those with visual impairment; figures very readable and the 'clear' button easily located on the side.
Lovely job, I really like it. Also it's a cute design.
