Rosewill RTMT-11001 Review

The RTMT-11001 and its packaging

Inside you will find a pretty ordinary thin molded plastic packing tray, including a 9v battery, and the user manual.

On the back of the box it includes the previously listed features and specs pictured in the user manual in 4 languages. The sides have some images representing the temperature range, shows it has a laser, and a 10:1 spot ratio. It also states on the box, and on a the thermometer that it was made in Taiwan, if that sort of thing matters to you.

There is a hinged battery cover that pops on and off with a friction fit, but no mechanical latch. It has a pretty standard 9v battery connector on wires, with a nice slot to hold the 9v battery but is also deep enough that it’s somewhat difficult to remove the battery for replacement.

The left side of the RTMT-11001 has a recess for opening the battery cover, and a sticker with all the cautionary and warning notes about the laser.

On the front of the RTMT-11001 you can see the scanning trigger, the IR Temperature sensor, and the laser emitter.


The right side of the RTMT-11001 has the same recess for opening the battery cover, and a sticker explaining the 10:1 ratio for distance to reading spot.

It is important to note that the size of the reading spot must be smaller than the surface being read for an accurate result.

  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…
