Product Information
Full details
This Laser DTI (Dial Test Indicator) gauge set is designed for automotive and engineering professionals who need precise measurements for critical components. Its key benefit is enabling accurate checks of engine, brake, and machine parts, ensuring optimal performance and alignment. A potential caveat is the need for a ferrous surface for the magnetic base to function effectively. The set includes two dial indicators of different sizes and a versatile magnetic stand, all housed in a blow mold case for portability.

FAQs
What is a DTI gauge used for?
A DTI (Dial Test Indicator) gauge is used for precise measurement of small distances or deviations, often to check for runout, alignment, or surface flatness on components in automotive and engineering applications.
What is the accuracy of the included DTI gauges?
The set includes a 60mm DTI with a range of 0-10mm and increments of 0.01mm, and a 30mm DTI with a range of 0-0.8mm and increments of 0.01mm, indicating high precision.
Can the magnetic base be used on non-metallic surfaces?
No, the magnetic base requires a ferrous (iron or steel) surface to attach securely. It will not work on aluminum, plastic, wood, or composite materials.
How do I attach the gauges to the magnetic stand?
The Dial Test Indicators typically have a stem or lug on the back that fits into a clamp on the articulated mounting post of the magnetic stand. Tighten the clamp to secure the indicator.
What is the benefit of the articulated mounting post?
The articulated mounting post allows for flexible positioning of the DTI gauges, enabling you to reach and measure components at various angles and locations, even in tight spaces.
How should I clean and maintain the DTI set?
Clean the indicators and magnetic base with a soft, dry cloth after use. Store the set in its original case. Avoid exposure to harsh environments and impacts.
What is the advantage of having two different sized DTI gauges?
Having two gauges with different measurement ranges (e.g., a larger range for general checks and a smaller, more sensitive range for fine-tuning) provides greater versatility and accuracy depending on the specific measurement task.
Troubleshooting
Magnetic base not holding securely
Ensure the mounting surface and the base itself are clean and free from oil, grease, or metal shavings. Confirm the surface is ferrous. Ensure the magnet is switched to the 'ON' position.
Indicator not reading zero or is inconsistent
Check that the DTI probe is making proper contact with the surface. Ensure the indicator is securely mounted and not vibrating. Verify the indicator's internal mechanism is not damaged; gentle cleaning might resolve sticking.
Articulated arm won't hold position
Tighten the locking knobs on the articulated arm firmly. If the arm still sags, there might be wear in the joints, requiring professional inspection or replacement.
DTI gauge is difficult to adjust
Ensure the articulated arm's locking mechanism is fully released before attempting adjustment. Check for any obstructions. If stiff, a small amount of appropriate lubricant may be applied to the joints (refer to manufacturer's specific advice if available).
Pros and Cons
Pros
- Enables highly accurate measurements for critical engine and machine components.
- Versatile magnetic base can be attached to various ferrous surfaces, including curved ones.
- Adjustable mounting post allows for precise positioning of the indicators.
- Includes two indicators with different ranges suitable for fine and general measurements.
- Comes with a protective and organized storage case.
Cons
- Requires a ferrous (iron or steel) surface for the magnetic base to attach.
- Not suitable for non-magnetic materials without an adapter (sold separately).
- Requires a learning curve to master precise positioning and interpretation for beginners.
- Indicator accuracy is dependent on the stability of the mounting surface.
Setup, Compatibility & Care
Setup:
- Ensure the magnetic base is clean and free of debris.
- Place the magnetic base on a clean, flat, or curved ferrous surface.
- Switch the magnet ON to secure the stand.
- Attach the Dial Test Indicators to the articulated mounting post.
- Adjust the articulated arm to position the indicator probe against the component to be measured.
- Switch the magnet OFF to reposition if necessary.
Compatibility:
- The magnetic base is compatible with all iron and steel surfaces. It will not adhere to aluminum, plastic, wood, or other non-ferrous materials.
- The DTI indicators are standard measurement tools and can be used with other compatible magnetic bases or fixtures.
Care:
- After each use, clean the DTI probes and the magnetic base with a soft, dry cloth.
- Avoid exposing the indicators to excessive moisture, dust, or impact.
- Store the set in its original blow mold case to protect the components.
- Periodically check the condition of the articulated arm joints and indicator probes for wear.
