Portable Infrared Thermometer for Automotive Diagnostics

Noncontact Temperature Measurement

AutoPro—

For The Automotive Technician.

Temperature variances can indicate common mechanical

and electrical problems. Diagnose them faster, safer and easier

with AutoPro™, the non-contact infrared thermometer specially

designed for the automotive professional.

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 measure-

ments often required for auto diagnostics. AutoPro can read temperatures up to

999°F (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.
