Rosewill RTMT-11001 Review

The back-lit LCD screen stays on for 6 seconds after releasing the trigger, and has ample brightness to read it nicely low or no lighting.

There is a display for the numbers, whether it is in Celsius or Fahrenheit, Scanning or displaying a temperature, and if the laser is on.

Below the LCD screen are buttons to switch between Celsius and Fahrenheit, and to turn the laser on and off.

The horizontal viewing angle of the LCD screen is pretty good for reading the temperature.

I was able to read it all the way up until the bezel blocked the view.

The vertical viewing angle is nowhere near as good as the horizontal. Being too far below a 90 degree angle the numbers get scrambled and

Too far above 90 degrees causes everything to disappear.

  1. These are great for any kind of workshop. They are nice to have in an automotive shop for brake concerns, cooling system temp drop across a radiator core, catalytic converter quick check and all sorts of other things. I may have to pick one up in the near future because I’m tired of having to borrow one all the time. Thanks for the review Mos.

  2. I’ve always wanted to measure difference between positive and negative pressure configuration, by measuring temps at intake and exhaust outlets, and comparing the two…

  3. Thanks guys.  It seemed rather difficult to review until I actually started playing around with it.  It’s kind of fun, find myself testing random stuff… “I wonder how crappy these windows really are”… Between this and a Kill-A-Watt, I bet a person could drop their utility bills a bit…

  4. One more use for it is a cat toy, lol. Shine the laser on the floor and enjoy. Works with little kids as well. My 2 year old chases it with the cat.

  5. We used to use a similar item when I worked in a supermarket.. when shipped they’re sometimes horribly un-calibrated! I’ve seen one out by 10 degrees (even though it quoted +- 2 degrees on the box). May not sound by much but when it comes to keeping your food at the right temperature for sale it’s important :) It could also mean the difference between ‘just cool enough’ and ‘magic blue smoke’
    How to check accuracy –  use crushed ice & water in a bowl. Firstly pack the bowl with crushed ice & then top up with water to give a

    slushy ice mix. This is a very accurate check – hell, it’s FDA and NZFSA approved and forms a part of NZFSA food shop checks :P
  6. I’m amazed you didn’t shoot yourself with it. -Or just shoot another thermometer. There’s gotta be something you can calibrate it with that doesn’t involve cooking.:D

    Body external temp can vary markedly depending on location – I worked in a 3 degrees C fridge all day :P
    For most purposes uncalibrated will work fine, but if you’re walking the cutting edge of performance, it may not be enough :P

  8. hah, I actually did use it on my arm, and I was at 94.  Of course, that was also just external temperature, and in a 70f apartment…
