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.
