Mitech MT150 Ultrasonic Thickness Gauge

Mitech MT150 Ultrasonic Thickness Gauge

Product Overview

The Mitech MT150 is a digital ultrasonic thickness gauge designed for accurate, non-destructive thickness measurement of metals and other materials that conduct ultrasonic waves. Using pulse-echo technology, this device allows users to measure thickness from only one side of the material, making it ideal for inaccessible structures such as pipelines, tanks, and pressure vessels. Compact and rugged, the MT150 is perfect for industrial applications including corrosion inspection, material quality control, and equipment maintenance in petrochemical, marine, aerospace, and manufacturing sectors.

Key Features

• Suitable for a wide range of materials including metal, plastic, ceramic, glass, and more

• Measuring range from 0.75 mm to 300 mm, covering both thin sheets and thick components

• Resolution of 0.1 mm for high-precision readings

• Single-side access required—ideal for enclosed or installed structures

• Supports zero and two-point calibration for enhanced accuracy

• Built-in velocity measurement mode for custom material calibration

• Visual coupling indicator provides real-time feedback for proper probe placement

• EL backlight for clear readings in dark environments

• Battery level indicator and up to 100 hours of operation with backlight off

• Durable casing, shock-resistant, and resistant to electromagnetic interference

• Portable and lightweight, designed for tough field conditions

Applications

• Inspection of wall thickness and corrosion in pipelines, tanks, boilers, and vessels

• Thickness monitoring in structural components of ships, aircraft, and machinery

• Non-destructive testing of metal sheets, plates, and composite materials

• On-site measurements in production lines and field environments

• Evaluation of high-temperature surfaces using specialized probes

• Quality control of materials where internal flaws or erosion may occur

Operating Guidelines

• Apply coupling medium (e.g., oil, water, or gel) between the probe and test surface

• Place the probe firmly and perpendicularly on the material surface

• For pipes larger than 4 inches, align the probe gap perpendicular to the pipe axis; for smaller pipes, take both perpendicular and parallel readings and use the smaller value

• When testing high-temperature surfaces, calibrate with a similar heated sample and use a suitable high-temperature probe

• For laminated or composite materials, account for internal air gaps that may distort measurements

• Regularly calibrate using reference blocks for accuracy

Maintenance and Storage

• Store the device in a clean, dry place away from dust, moisture, and magnetic fields

• Do not open or modify internal components—contact authorized service for repairs

• Clean the device with a soft, damp cloth; avoid abrasive or chemical cleaners

• Transport in the original packaging, especially for field deployment or shipment
