The Diagnostic Thermal Imager Elite from Snap-on uses infrared technology to reveal heat caused by friction, electrical resistance, pressure changes, and more to track down vehicle faults and find the fix faster, the company says. It delivers detailed images composed of 4,800 distinct temperature zones, making temperatures up to 840 degrees F visible with improved precision. A database of automotive applications, guided tests, and reference images help to interpret results. When connected to Wi-Fi, images captured with the Diagnostic Thermal Imager Elite are uploaded to the cloud via Snap-on's Wi-Fi sharing service, AltusDrive.com.
