The handy Dual Display Indoor/Outdoor Thermometer with Alarm will give you all the temperature-based data you'll need from both inside and outside the greenhouse to keep your plants safe - and with the additional bonus of a low and high temperature alarm alert, you can put in place heaters or ventilation to ensure plants never dry out or suffer frost damage again!

The indoor/outdoor thermometer has a host of features; an easy-to-read digital display screen measures 36mm wide by 16mm high; flip between celcius and farenheit readings and set the alarm with simple push button controls and the wide temperature range (-20°C to +70°C indoor and -50°C to +70°C outdoor) will cope with all the extremes of British weather. A dual display reveals the current indoor and outdoor temperature simultaneously by way of a built in thermostat and probe respectively and the max/min memory function allows you to find out what happened temperature-wise during the day or night in your absence. The alarm function warns if a minimum or maximum temperature of your choice has been reached or exceeded, and with full instructions and 1 x AAA battery included, you'll take complete climate control of your greenhouse or potting shed in no time!
