Krautkramer SpotChecker Ultrasonic Spot Weld Tester

A truly mobile soultion for spot weld testing offering significant gains in productivity.

Spotchecker is hand-held flaw-detector for testing spotwelds in situ on the production line.
It weighs just 3.2 kg, is battery operated and is sealed to IP65. It features hot swap battery exchange to ensure continuous operation.
Spotchecker does not require intensive training but offers the advantage of an “expert” system for people less qualified in weld inspection.


SpotChecker “completes” our existing USLT product line for spot weld testing. It offers true portability with a rugged, environmentally protective housing. The key difference between this product and existing spot weld testing solutions is its size/weight, environmental protection and user friendly operating.
