Yes. Thermal imaging cameras are suitable for detecting overheating connections, overloaded circuits, and faulty components.

No. Thermal imaging cameras measure surface temperature only. They cannot see through walls or glass. Glass reflects infrared radiation, so measuring through a window will show the glass surface temperature.

Yes, under the right conditions. The TD2e can detect refrigerant leaks from air conditioning systems. Tips for best results: Detection distance: Start at approximately 1 meter from the suspected leak point Pressure matters: Detection works best when the system is pressurized (e.g., 2MPa in heating mode). Pressurizing or holding pressure before testing improves results Sensitivity threshold: For context, a leak producing at least 1 bubble every 3 seconds in water is detectable Background noise: Placing sound-absorbing material (e.g., sponge) behind the pipe can help reduce noise interference

Yes. Compressed air leak detection is one of the most common applications for the TD Series. The device can quickly locate leaks in compressed air systems, pipelines, and fittings without the need for soap spray or contact methods. Recommended frequency range: 20kHz - 40kHz for best results.

No. The TD Series detects sound waves that travel through air. Walls and solid barriers block or absorb these sound waves, preventing the device from detecting sound sources on the other side.

Yes. Vacuum and negative pressure leaks can be detected using the same principle as positive pressure leaks. The escaping gas (now entering the system) creates turbulence that generates sound waves within the detectable frequency range. Tip: Position the device at a 45° to 90° angle relative to the suspected leak point. Smaller angles may not receive the acoustic signal effectively.

Not directly. The TD Series detects airborne sound waves. Water leaking inside a wall or underground does not produce sufficient airborne ultrasonic signals for the device to detect. However, if a water pipe is exposed and a leak is present, pressurized water escaping can generate detectable sound. For wall-pipe leaks: A thermal imaging camera (e.g., FOTRIC thermal cameras) is a better choice, as it can detect temperature differences caused by moisture in the wall.

Yes. The TD Series is designed for use in industrial environments (non-explosive areas). In noisy settings, you can adjust the following to improve detection: - Frequency range: Adjust to filter out background noise and focus on the target sound's frequency - Noise Suppression Mode: Filters out low-level sounds to reduce environmental interference - Acoustic Image Focus: Focus on a specific region to minimize surrounding noise - Sound source mode: Switch between Single-source, Multi-source, or All-source mode as needed With the right settings, the device can effectively isolate and locate target sounds even in loud environments.

A thermal imaging camera detects infrared radiation (heat) emitted by objects and converts it into a visible image. The spectral response range is 8~14μm. The device is passive — it only receives heat radiation, it does not emit any signals, so there is no radiation concern.

The FOTRIC TD Series uses an array of 64 MEMS microphones that capture sound from multiple directions at once. When a sound is made, it reaches each microphone at a slightly different time. The device calculates these tiny time differences to determine exactly where the sound is coming from, then overlays the sound source location as a colorful heatmap on the live camera image. In simple terms: it lets you "see" where sounds are coming from — even sounds that are too quiet or too high-frequency for the human ear to hear. The device is passive — it only receives sound waves, it does not emit any signals, so there is no radiation concern.

Once the returned item arrives at our warehouse and passes inspection, the refund will be issued to your original payment method within 5–7 business days. Processing times may vary depending on your payment provider.

Most orders are processed and shipped within 1–3 business days (Monday–Friday, excluding US federal holidays). You will receive a shipping confirmation email with your tracking number as soon as your order has been dispatched.

If you are experiencing a black screen, severe lag, or visual artifacts when using the TD2 Geek with your phone, this may be a software compatibility issue with certain phone models. The TD2 Geek requires an Android phone with Android 12 or above and OTG function enabled. Please make sure these are met first. If the requirements are met and the issue persists, please contact us with your phone model and order number. Our technical team will investigate and provide a solution. Known issue: Some Xiaomi models running HyperOS have a confirmed compatibility issue. A fix is currently under development.

This is a known issue with early TD2 units. When the battery level drops below 20%, the device may not charge through the USB-C port or power on. Solution: Use the charging dock that came with your TD2. Remove the battery from the device, place it into the charging dock, and let it charge for a few hours. Once charged, reinstall the battery and the device should operate normally. If your TD2 did not come with a charging dock, please contact us and we will send you one free of charge. Note: This issue has been resolved in newer production units.

The dB value displayed on the screen represents the Sound Pressure Level (SPL) detected at the measurement distance. It is a measure of the acoustic signal's intensity at the device's position, not a percentage or a simple "loudness" value. These values are useful for comparing the relative intensity of different sound sources during inspection.

- Compressed air leak detection Recommended frequency: 20kHz – 40kHz Small leak signals peak in this frequency band, where background noise is the lowest, making leaks easier to identify. - Vacuum / negative pressure leak Recommended frequency: 30kHz – 60kHz This is the recommended starting range for locating vacuum and negative pressure leaks. - General inspection / unknown source Recommended frequency: 2kHz – 100kHz This enables a full-range scan for TD2 and TD2e models. For the TD2 Geek, the full usable range is 2kHz – 50kHz. The default settings are a starting point. For best results, adjust the frequency range based on what you're trying to detect.

For valid quality-related claims, FOTRIC will: -Provide a factory-refurbished product of equivalent value -If a refurbished model is unavailable, a brand-new product will be sent -If a replacement is not possible or preferred, we offer a partial refund based on the device's usage time Replacement products may differ slightly in appearance or value due to technical updates.

The TD2 and TD2e cover 2kHz to 100kHz. This range covers most common applications: Gas leak detection — typically 20kHz–40kHz ✅ Applications above 100kHz — ❌ These are beyond the device's detection range If you are unsure whether the device is suitable for your specific application, please contact us before purchasing.
