TI-007X Series Precision Ultrasonic Wall Thickness Gauges


Important Note: The TI-007X and TI-007DLX models are now part of the TI-007X Series. All specifications, comparisons, and pricing of the TI-007X Series are provided below.

The TI-007X Series from Checkline is a high-precision range of ultrasonic wall thickness gauges designed for thin materials, challenging surfaces and critical applications. With measurement capabilities starting from 0.15 mm and resolution down to 0.001 mm, these gauges are ideal for precision engineering, quality control and research environments.

Available in two versions—TI-007X and TI-007DLX—this series combines durability, intuitive operation and advanced functionality. The DLX model includes onboard memory and USB connectivity for seamless data management.

Key Features (varies by model):

  • Wide Measurement Range: From 0.15 mm to 915 mm depending on the probe, suitable for a broad range of applications.
  • High Resolution: Offers precision down to 0.001 mm for thin-wall measurements and near-surface flaw detection.
  • Multiple Measurement Modes: Includes Interface-Echo (I-E), Echo-Echo (E-E) and Plastics (PLAS) mode for optimal results on different materials.
  • Scan Mode: Captures up to 100 readings per second; displays the lowest value for maximum control during drag scanning.
  • Data Logging (DLX only): Stores up to 10,000 readings in 40 batches of 250 entries each.
  • USB Output (DLX only): Easy file transfer, recognised directly as a storage device—no special software required.

Key Benefits:

  • Quick & Accurate Setup: Auto calibration using a known thickness sample with automatic speed of sound calculation.
  • Visual Clarity: Large, backlit LCD with live display and stored last reading for efficient workflows.
  • Reliable in Tough Environments: IP65-rated extruded aluminium housing ensures resistance to dust and water.
  • Certified Accuracy: Supplied with NIST traceable calibration certificate.
  • Extended Warranty: Up to 5 years of coverage for long-term peace of mind.

 

This compact yet powerful device is the ideal solution for professionals needing reliable, high-resolution measurements on a wide variety of materials—metals, plastics, and beyond. The TI-007X Series delivers the accuracy and resilience required in modern industrial and research applications.

Features

  • Measurement Modes: Interface Echo (I-E), Echo-Echo (E-E), and Plastics (PLAS)
  • Scan Mode: Captures 100 readings per second; displays the minimum value detected during scanning
  • Adjustable Gain: Five-step gain adjustment for optimised measurement on challenging materials
  • Custom Calibration: Automatic velocity adjustment based on sample thickness; custom speeds can be stored
  • Display: Large backlit LCD with last reading memory
  • Resolution: 0.001 mm for high-precision thickness evaluation
  • Environmental Protection: IP65-rated aluminium housing for water and dust resistance
  • PC Connectivity: USB output for direct file transfer without software (TI-007DLX only)
  • Data Logging: Stores up to 10,000 readings in 40 batches (TI-007DLX only)
Complete Kit

The TI-007X Series is supplied as a complete kit with:

  • TI-007X or TI-007DLX wall thickness gauge,
  • transducer: T-402-5507 1/4" 15 MHz with delay line tip,
  • 120 ml bottle of coupling gel,
  • 2 AA batteries,
  • NIST traceable calibration certificate,
  • operating manual,
  • USB-C data transfer cable (TI-007DLX only),
  • all in a foam-fitted plastic carrying case.

 

Data transfer software is not required — the device is recognized as an external drive for direct file access.

Optional USB-C Cable:

For the TI-007X model, the USB-C cable is available as an optional accessory.
