New Multiple-Echo digital ultrasonic thickness gauges measure remaining metal thickness without need to remove protective coatings.
The range of five new instruments incorporate two additional measuring modes. Single-Echo measures uncoated surfaces with heavy front face and/or back-wall corrosion and attenuative materials like cast metals. Echo-Echo measuring mode is for painted metals but with heavy back wall pitting for improved back wall detection.
Among thickness gauge features: A-scan and B-scan displays, hands-free units for climbing or rope access, and simple sequential or comprehensive data logging with such features as grid format and vibrate alert to warn when measurement is out of tolerance.
