I recently saw the Etekcity 8250 thermometer online and thought it looked like a cheap tool / gadget / toy / distraction that might have some actual use. A non-contact thermometer has a thousand household uses, right? I can’t actually remember the last time I needed to measure the temperature of something but this will be a tool of curiosity.
I conveniently forget about the order and was pleasantly surprised when it arrived. What’s the first thing you do with a thermometer?
Measure against a convenient and known standard, human body temperature.
Human body temperature – measured at 92.1° F
Hmmm, at first glance this doesn’t appear to be correct but skin temperature is not the 98.6° F core temperature that I was expecting. Some quick Googling reveals a narrow range of expected skin temperatures with 90° F at the lower end.
How about some other known (and convenient) standards?
Ice cubes – measured at 11.0 °F
Ice from the freezer? Convenient and cold. 11 °F sounds about right.
Flame – measured at 172.5 °F
Lighter? Hot and tricky to measure. Very difficult to get a direct flame measurement. Core flame temperature is expected at around 3,500 °F. The thermometer is measuring the outside of the flame and the thermometer maxes out at 482 °F. Inconclusive.
Room temperature – measured at 69.3 °F
How about an independent standard? My AcuRite 02023 indoor/outdoor thermometer is on par with the Etekcity measurement. Seems legit.
In conclusion? A capable thermometer to keep in my kitchen drawer. Easy to use and instant temperature readings. It seems capable for cooking and curiosity measurements but I don’t think I’ll be using this for hard science any time soon.
