Raytek ST25 Portable infrared thermometer for automotive diagnostics.

Temperature variances can indicate common mechanical and electrical problems. Diagnose them faster, safer and easier with the Raytek ST25 AutoPro, the non-contact infrared thermometer specially designed for the automotive professional. Raytek's ST25 AutoPro features SmartSight - two lasers merge into a single laser point to indicate a half inch (13mm) target, an ideal spot-size for small area measurements often required for automotive diagnostics. AutoPro can read temperatures up to 535°C, and can accurately measure in low light conditions, illuminating the work area with a built-in LED flashlight. AutoPro also features an illustrated, step-by-step user manual with detailed instructions for many common automotive diagnostic procedures, including engine misfires, exhaust and emissions, cooling systems and heating and air conditioning systems. Get the thermometer designed especially for automotive technicians - the Raytek ST25 AutoPro.

Typical Applications

Spot size

The relationship between distance and spot size is 16:1 at the focus point (200mm: 13mm or 8 inches: 0.5 inch). As the distance (D) from the object decreases or increases, the spot size (S) of the area measured by the unit becomes larger. The spot sizes indicate 90%-encircled energy.
