You can buy thermometers that read remotely via a sensor so it will read whatever the temp is where the sensor is located. I have one for my reptiles. It allows me to see what the temp is in the habitat, from another part of the house. It works a little like a baby monitor in that you have two units. One is the thermometer that measures the temp and the second unit displays the temp for you. When I incubated the first time, I kept the unit beside my bed even though my incubator was in another room. This allowed me to check the temp in the incubator without getting out of bed. I would try a pet store - that's where I found mine.
