Simple stick or dial thermometers are great for a quick read of the temperature. But what if you want to know the humidity as well? And the high and low temperatures for the day?
Digital thermometers also have another key advantage over analog thermometers: the remote sensor can be placed away from buildings and other heat sources. (The best place is on a post or in a shaded area about four feet above the ground). That makes the sensor more accurate than thermometers next to a window, which can be influenced from the heat from inside.
After trying out five different digital options, we think ThermoPro TP60s is the best indoor and outdoor thermometer that also reads humidity (technically, these are called hygrometers).
What We Liked
• Digital 2.7″ display is easy to read.
• Records minimum and maximum temperature in the last 24 hours. That’s nice to know, as temperature trends are almost as important as the current temp.
• Sensor can be 200 feet away from main display.
• Runs on AAA battery which is included.
• Simple to set up and use.
• Can add up to 3 outdoor remote sensors, in case you want to monitor a greenhouse, chicken coop or other out building.
• Low battery indicator.
• Trend arrow shows if temp is rising or falling.
What Needs Work
• Temperature range only goes as low as -4 degrees Fahrenheit. If you live in a colder climate (we are looking at you, folks in Maine), you might want a different option with a larger low range.
• Can’t wall mount the unit if you want to check the min/max temps. That’s because the button that shows you the high and low temps is on the side of the unit.
• No back light. Yes, the maker has another model that does offer this feature . . . but this model doesn’t—and that makes it hard to read in the dark!
• Eats batteries. One tip: use lithium instead of alkaline batteries. They last longer and do better in extreme temps (cold or hot).
