ShockWatch Tube – When to Use the Embedded Impact Indicator
The ShockWatch® Tube is SpotSee’s original embedded impact indicator, designed for manufacturers who need tamperproof, internal monitoring of shocks and drops. Unlike surface-mounted indicators such as ShockWatch Clip, the Tube is installed inside the product during assembly, providing hidden, permanent evidence of mishandling throughout the product’s lifecycle.
As a SpotSee partner, Good Life Innovations supports OEMs and engineering teams in selecting and integrating ShockWatch Tubes into their quality-control and warranty processes.
What Is the ShockWatch Tube?
The ShockWatch Tube is a sealed glass tube containing a reactive liquid. When the product experiences an impact above the selected G-level, the liquid moves into the activation chamber and permanently turns red. This provides a clear, irreversible record of mishandling.
Because the Tube is embedded inside the product, it cannot be tampered with, removed, or replaced without detection.
How the ShockWatch Tube Works
The Tube uses SpotSee’s proven mechanical activation technology:
- A sealed glass tube contains a reactive liquid
- When an impact exceeds the rated threshold, the liquid travels into the activation zone
- The indicator permanently turns red
- The activation cannot be reset or reversed
This makes the Tube ideal for warranty validation, calibration-critical equipment, and products that undergo multiple handling stages.
When to Use the ShockWatch Tube
The Tube is best suited for applications where the impact indicator must be hidden, protected, or integrated into the product itself. Typical uses include:
1. OEM manufacturing and assembly
- Medical devices
- Optical systems
- Precision instruments
- Electronics and control units
2. Warranty and service validation
The Tube provides tamperproof evidence of mishandling, helping manufacturers distinguish between product faults and impact-related damage.
3. Calibration-critical equipment
- Laboratory instruments
- Measurement devices
- Scientific equipment
4. Products with internal housings
The Tube can be mounted inside enclosures, frames, or custom brackets.
ShockWatch Tube vs ShockWatch Clip
Both devices use the same internal tube technology, but they serve different purposes:
| Feature | ShockWatch Tube | ShockWatch Clip |
|---|---|---|
| Mounting Location | Inside the product | On the product surface |
| Visibility | Hidden | Always visible |
| Best For | OEM integration | Equipment-level monitoring |
| Tamper Resistance | Very high | High |
Need a surface-mounted version?
If you need an impact indicator that mounts on the outside of the product, see the ShockWatch Clip – When to Use the Surface-Mounted Impact Indicator. It provides tamperproof, on-product monitoring without requiring OEM integration.
Installation Best Practices
To ensure accurate performance:
- Mount the Tube in a rigid, non-flexing area of the housing
- Use a secure bracket or enclosure
- Select the correct G-level based on product fragility
- Ensure the Tube is accessible for inspection during service
Benefits of Using the ShockWatch Tube
- OEM-grade embedded monitoring
- Highly tamper-resistant
- Ideal for warranty and service validation
- Clear, irreversible evidence of mishandling
- Suitable for sensitive or high-value equipment
Is the ShockWatch Tube Right for Your Application?
Choose the ShockWatch Tube if you need an embedded, tamperproof impact indicator for manufacturing, calibration-critical equipment, or warranty validation.
Good Life Innovations, as a SpotSee partner, can help you select the right sensitivity and integrate ShockWatch Tubes into your production or quality-control workflow.
