The AccuTAP TT-42 automated tap tester replaces traditional tap hammers used for inspecting structural bonded parts, which rely on the operator’s ear and years of experience. By using a force sensor to deliver quantified results—shown through LEDs, an alarm, and OLED readout—the TT-42 eliminates subjectivity and ensures consistent accuracy even in noisy environments.
The AccuTAP TT-42 is a great lower cost alternative to the WP-632AM-R Woodpecker Automatic Tap Tester.
Quantitative inspection via force sensor input, replacing subjective “tap hammer” methods
