TT130 pulse-echo ultrasonic thickness gauge for wall thickness of metal plates, pipes and vessels from one side.
Overview
The TT130 TT130 Ultrasonic Thickness Gauge consists of a main unit and a probe. It works on the ultrasonic pulse-echo principle: pulsing electronics excite the probe, the sound wave travels through the material and is reflected by the back wall, then a microcontroller computes thickness from the known sound velocity and the round-trip time, displayed on the LCD. Microprocessor-controlled, it is accurate, compact, light and easy to operate; with a known sound velocity it non-destructively measures steel plate/pipe, cast iron, plastic, ceramic and glass. Widely used in petrochemical, power, boiler/pressure-vessel and pipeline wall-thickness corrosion inspection.
Applications
• Road and highway engineering laboratory testing
• Construction material quality control and acceptance
• Research and teaching laboratories
• Third-party inspection and certification bodies
Features
• High measurement accuracy with stable repeatability
• Large LCD display showing real-time test parameters and results
• Robust construction suitable for both laboratory and field use
• Compliant with relevant Chinese and international testing standards
• Complete with calibration certificate and operation manual

FAQ
Q1: What standards does the TT130 Ultrasonic Thickness Gauge comply with?
A1: The TT130 Ultrasonic Thickness Gauge is designed and manufactured in accordance with relevant Chinese national (GB) and transport industry (JTG) standards, as well as applicable ASTM and AASHTO international standards. A calibration certificate traceable to national standards is provided with each unit.
Q2: How often should the TT130 Ultrasonic Thickness Gauge be calibrated?
A2: We recommend annual calibration by authorized technicians or by iRoad after-sales service center. For high-frequency laboratory use, semi-annual calibration is advised. The instrument is supplied with a factory calibration certificate.
Q3: What is the lead time and do you provide training?
A3: Standard units are usually shipped within 7-15 working days. Custom configurations may require 20-30 days. iRoad provides on-site installation, commissioning and operator training for major equipment; remote video guidance is available for standard laboratory instruments.
