Overall the Rosewill RTMT-11001 Infrared Thermometer has been rather impressive to me. I wasn’t expecting it to feel as well built as it does. On the sample that I am reviewing at a distance of 10 inches from the object surface being read, the laser is a little over 1/2 inch high. At a distance of 20 inches, it’s just under 1/2 inch too high, and at 30 inches it’s right around 1/4 inch too high. I consider this acceptable when it’s noted that the center of the laser emitter is 3/4 inch above the infrared sensor.
I set up a pot of boiling water with my cooking thermometer clipped to the side right where the water line was. I brought it up to a boil and the cooking thermometer read 212.4F degree average over 3 readings. I used the RTMT-11001 to get an average temperature reading of 214.2F. While letting it cool off, I got a reading of 174 on the cooking thermometer and 173 with the RTMT-11001. While I can’t guarantee the 100% accuracy of my cooking thermometer, the RTMT-11001 was close enough for me.
After leaving my TV on for about 2 hours of cooking, cleaning, and other testing with the RTMT-11001 I took some readings on the back of my TV for a nice matte surface reading. At a distance of 10 inches I was getting a reading of 83.5F, at 20 inches I was getting 83.5F, and at 30 inches I was reading 81.3F. These results were mirrored when I measured temperatures for the front of the TV, and a wall. It was always 1-2 degrees lower at 30 inches than at 10 or 20. The user manual does not include a minimum or maximum reading distance, so this could be normal behavior for it.
With the vertical and horizontal viewing angle issues of the RTMT-11001, it was somewhat difficult to read when used to read temperatures of various computer components. I learned to come at things sideways so I could still read the screen. It does not have to be aimed perfectly perpendicular to the surface, but I just feel better getting it as close to it as I can. Otherwise it is compact enough that it wasn’t too difficult to use inside of an Antec P180-Mini, Fractal Design Define Mini, or a Corsair 600t.
Back-lit LCD makes the screen easy to read in any lighting condition.
Construction feels sturdy and rugged. Buttons feel more robust than many.
Switchable between C and F is nice
Seems accurate enough based on my testing
Inexpensive for a good value
Vertical viewing angle is pretty poor, making it difficult to read.
Delay between pulling the trigger and the sensor turning on.
Sometimes wished the screen would stay on a little longer.
