cheap dual temp thermometer,
Verified Purchase(What is this?)
This review is from: Silverline 675133 Indoor/Outdoor Thermometer -50 Degree Celsius to +70 Degree Celsius (Tools & Hardware)
I bought this thermometer with some trepidation as I didn't know if the outside temperature probe wire would go through my windows without being split. As it turns out most double glazing windows have a rubber seal around the frame. This seal has enough give to safely allow the outside probe wire to pass through.
Onto the product, I like it. I have found the temperatures accurate, but don't place in direct sunlight. It doesn't come with a AAA battery but I had some lying around. The best thing is being able to compare both inside and outside temperatures.
