Need to keep an eye on the temperature in your fridge, freezer, greenhouse, or reptile tank? This digital thermometer with a super long 1.5-meter (almost 5 feet!) sensor cable is exactly what you need. The main unit has a clear, easy-to-read LCD screen that shows the temperature in real-time, with an accuracy of about 1°C and a resolution of 0.1°C. That means you can tell if your freezer is creeping up from -18°C to -17°C before your ice cream melts! The probe on the end of the long cable lets you place the sensor deep inside a freezer or an incubator while the display sits outside where you can see it. It measures a wide range from a freezing -40°C all the way up to 70°C, so it's super versatile. It runs on included LR44 batteries and is small enough to stick on a wall or fridge door. Perfect for home brewers, gardeners, pet owners, or anyone who needs to monitor climate-sensitive stuff. It takes the guesswork out of temperature control and gives you peace of mind. A handy, affordable tool for your home or hobby.
