Product Description

The Raytek AutoPro ST25 infrared thermometer has two separate lasers that converge to create a single bright laser point when the optimal distance from the object is being measured. It has a one-percent accuracy temperature measurement. The instruction manual covers automotive diagnostic applications including engine misfires, catalytic converters, heating and cooling systems, A/C systems, track and tire temperature, and substrate temperature.

Customer Reviews

Reads 8 F degrees high, but consistent
I bought this unit to use the dual laser dots as an aid to knowing exactly what it is I am measuring, when wanting a reading on RC craft motors and on the ICs of electronic circuit boards. Compared to my Raytek Mini Temp MT, which has no laser at all, this new ST25 reads 8F degrees high, but it is consistent over a range of items from 40 to 180F that I tested. I presume the MT model is right, or at least close, because I can scan most any item in my home office and the surface will usually match the temperature in the room, about 72F at the time of testing. The ST25 would show the same item at 80F. I know it isn't 80 in here, because I would be sweltering if it were.

Although I am disappointed that the device is apparently incorrectly calibrated, I can subtract the 8 degrees and it then seems to correctly measure everything I pointed it at. A calibration adjustment for the user would make a nice addition to this model.

The ST25 seems solidly built and I was surprised by how much larger in size it is compared to the mini MT. It comes in a nice molded carry case with a manual that describes several items that can be tested, including such things as rear window defroster traces and other automotive items. The manual is in several languages.

Excellent
Accurate, easy to use. Nice feature to be able to scan many areas (by sweeping the beam back and forth or around an area) and have the high temp of the entire area scanned displayed separately from the temp of the spot at the time of measurement.
