Comparing the Kintrex IRT0421 Non-Contact Infrared Thermometer with Laser Targeting with Competition

kintrex irt0421

While there are a number of infrared thermometers out there, the SURPEER IR5D Non-Contact Laser Thermometer Gun has happened to give the Kintrex IRT0421 thermometer the toughest call.

Both products come from reliable brands and have earned a distinguished position on the market.

Here’s a detailed comparison between the two to make things clearer.


Both thermometers are made from high-quality materials, so there is no question about the durability.

 They are compact and lightweight, offer non-contact functionality, and feature an infrared sensor that can accurately measure the temperature readings. The results are displayed on a backlit LCD to allow convenient reading.

Another similarity between these thermometers is that both of them allow you to take the temperature readings in a unit of your choice, be it Fahrenheit or Celsius.

Being versatile, you can use any of them for various purposes, from automotive diagnostics to food preparation and from industrial testing to HVAC service.


While there are a number of similarities between these thermometers, they have their differences as well. First of all, the major difference is the measurement range.

 While SURPEER IR5D Non-Contact Laser Thermometer features a reading range -58℉ to1112℉ (-50℃-600℃), the Kintrex IRT0421 thermometer surpass it by measuring temperature from -76 to 1157℉ (-60 to 625℃).

Similarly, the Distance-to-Spot ratio of SURPEER IR5D Non-Contact Laser Thermometer is 12:1 while that of the Kintrex IRT0421 thermometer is 16:1.

 This means the latter is capable of measuring temperature from a much longer distance.

 While both models are battery-operated, the Kintrex IRT0421 thermometer uses two AAA batteries, and the SURPEER IR5D Non-Contact Laser Thermometer requires a 9V battery to run.

Finally, when it comes to the warranty, SURPEER IR5D has only a one-year warranty, while the Kintrex IRT0421 comes with a relatively longer two-year warranty.

Issues & Concerns

Since each product has its flaws, the Kintrex IRT0421 non-contact infrared thermometer with laser targeting has its drawbacks as well. These include:

Varying measurements:

One of the major concerns is that the positioning and placement of the thermometer might affect the measurement.

 Some other factors like environment, positioning, or a cover can alter the readings. Similarly, the accuracy might get disturbed while measuring extreme temperatures.


Bring a specialty meter, price can be a concern for those on a tight budget. It has some unique and high-end features and, therefore, comes with a hefty price tag. However, if the price is not an issue, it is worth the investment.

Unable to measure liquid and gas:

Since it is an infrared thermometer, the Kintrex IRT0421 can’t take temperature measurements of liquid and gas.It works only on solid surfaces, that too, within a definite range.

Care and Maintenance


While durability is an important factor, proper care and maintenance can extend the lifespan of the device. Here are some key points to remember.

  • You must keep infrared thermometers free of dirt, debris, fog, and moisture to uphold their accuracy.
  • It is always suggested to take some time and clean the thermometer after exposure to a humid, dusty, or smoky environment.
  • Try using a soft cloth to clean the lens of the thermometer.
  • Always store it carefully like in a bag and avoid storage in extreme temperatures.
  • Handle it carefully to prevent shocks and drops.


The Kintrex IRT0421 non-contact infrared thermometer with laser targeting is functional, versatile, and durable. A two-year warranty from the manufacturer serves as the cherry on top.
