About this part

This is the ProTek R/C "TruTemp" Infrared Thermometer. Any temp gun can give you a reading, but the accuracy of that reading is always questioned - especially when dealing with cheap guns from questionable sources. When you have thousands of dollars invested into your equipment, a questionable number isn't good enough. You need accuracy, dependability and simplicity.  

The "TruTemp" is a highly useful non-contact tool specially designed for use with R/C engines, motors, battery packs, battery chargers, electronic speed controllers, as well as hundreds of other applications. To use, simply aim the infrared thermometer at the target and press the measurement button to quickly and easily display the surface temperatures.

Most people think a cheap temp gun is good enough, but cheap temp guns provide untrustworthy measurements. Put your equipment in the hands of precision, with the ProTek R/C TruTemp.

Good little temp gun, I would recommend this to anyone not wanting to spend $250 on the alternative.

Great temp gun! Easy to use, very accurate even when tested against much more expensive temp guns too. I have been using this gun for the past several weeks and it has worked extremely well.

The Tru Temp works awesome. It's easy to read at night for club racing and is very accurate. I compared its temps to a very expensive unit and its reads the same (within a degree or two). I highly recommend especially if you're a racer. It also works great for my electric stuff too.

What reviewers say

Reviews are sharply split. Many owners report accurate, easy-to-read readings, good screen brightness, long battery life and durability over years of use, and several compare favourably with more expensive units. Others report readings many degrees off, especially at higher temperatures, with some attributing errors to a possible software or calibration issue. Physical build complaints include brittle housing, broken internal wires after about a year, and a screen that scratches easily. One reviewer said the mode and unit settings reset on power-up. Several reviews are from verified owners and the rest are unverified; no variant differences are noted.

  • + Accurate readings for many owners
  • + Easy to read, bright screen
  • + Long battery life
  • + Good value for the price
  • − Readings off by many degrees for some
  • − Brittle housing and broken internal wires
  • − Screen scratches easily
  • − Settings do not persist after power-off
