The ThermoPro TP-450 Temperature Gun is a narrow focus infrared measuring tool. It contains a unique two-laser aiming system that you can use to measure the surface temperature of any object.
How to Use the ThermoPro TP-450
Squeezing the trigger on the ThermoPro TP-450 turns on the detector and twin laser beams that indicate the area you are measuring. The spot-distance ratio is 16:1 which is quite a narrow window. This facilitates measuring the surface temperature of a small area. The two lasers indicate the 12 o’clock and the 6 o’clock positions on an imaginary circle that lies between them. This makes the area you are measuring easy to determine. Because of the locations of the lasers, there is no parallax error. As an added bonus, the two red dots were great for confusing my cat!
The resolution of the ThermoPro TP-450 is 0.1°, and the claimed accuracy is 1.5 percent which is a bit optimistic, in my opinion. Because different surfaces emit different amounts of energy (black = high; shiny = low), the value of emissivity set in the tool is critical if high accuracy is desired. An emissivity value of 0.95 is the default setting which users can change. Because of this dependency, take the measurement with a grain of salt.
The display shows two values: the instantaneous reading at the top, and a minimum/maximum/average reading below. The user can cycle through the three values with the push of a button. You can turn the laser off if desired.
Our Review
As for the build quality, the ThermoPro TP-450’s seems high, including a solid feel to the housing. The required batteries are AAA which you can find easily. The documentation is detailed and well-written. The thermometer comes with a one-year limited warranty. The contact information includes telephone numbers and an e-mail address should technical support be needed.
The ThermoPro TP-450 Temperature Gun is one of the nicer IR thermometers I’ve tested. Plus, the price point is attractive, earning it an easy Gold Medal.
