Product Description
Traditional ultrasonic thickness testing requires grinding off paint, epoxy or anti-corrosion coatings, which damages workpieces and raises labor & time costs. The Laurel S004 through-coating ultrasonic thickness gauge adopts Echo-Echo ultrasonic technology to directly read base metal thickness through up to 3mm non-metallic coatings, realizing full non-destructive inspection. This high-precision portable NDT instrument supports thickness measurement & sound velocity reverse calculation for steel, aluminum, copper, plastic, glass and ceramics, widely deployed in machinery, petrochemical, marine, aerospace and automotive industries.
Functional Features
1、Through-Coating Echo-Echo Measuring Mode
Feature: Penetrate coatings up to 3mm thick, dual working modes (Standard / Through-coating)
Advantage: Automatically filter coating echo signals, only output real substrate thickness
Benefit: No surface grinding, save coating repair cost, 70% faster on-site inspection efficiency
2、0.01mm Ultra High Resolution & Precise Accuracy
Feature: Resolution 0.01mm, accuracy ±(0.6%H + 0.05) mm, H=workpiece actual thickness
Advantage: Capture tiny thickness loss caused by corrosion, fit strict industrial quality control
Benefit: Avoid missed pipeline & vessel corrosion risks, reduce equipment failure loss
3、500–18000 m/s Wide Sound Velocity Calibration Range
Feature: Support sound velocity calibration via known thickness block, reverse calculate material acoustic speed
Advantage: Compatible with steel, cast iron, aluminum, copper, plastic, glass, fiberglass, ceramics
Benefit: One device covers all common ultrasonic conductive materials, cut procurement cost
4、Aluminum-Magnesium Alloy Shockproof Housing
Feature: Compact 145×70×32mm alloy shell, anti-vibration, anti-impact & anti-electromagnetic interference
Advantage: Stable performance under harsh workshop, offshore, outdoor construction environments
Benefit: Long service life, no frequent replacement of testing equipment
5、Long-Lasting Lithium Battery with EL Backlight
Feature: Over 160h continuous working without backlight, auto sleep & auto power-off energy-saving, bright EL backlight
Advantage: All-day field inspection without frequent charging, clear reading in dark warehouses & night operation
Benefit: Eliminate power outage interruption during long-term engineering detection
6、Humanized Multi-Language Operation System
Feature: Switch metric/imperial units, Chinese & English UI, coupling status real-time indication
Advantage: Easy operation for global technicians, real-time remind poor probe coupling
Benefit: Reduce operation error, lower training cost for new inspectors
