Why do the sides of the device get warm during use?
+
This is normal. The internal processor continuously calculates real-time acoustic data from all 64 MEMS microphones, which generates heat. The side label areas are specifically designed as heat dissipation zones.
Can I analyze the exported images in PC software?
+
You can export images to a computer via the USB Type-C port or by removing the SD card (supports up to 1TB). The files are saved as standard JPGs showing the acoustic heatmap overlay. Because they do not contain raw acoustic data, they cannot be further analyzed or manipulated in PC software.
How long does the battery last and how do I charge it?
+
A single battery provides ≥3 hours of continuous operation. The battery is field-replaceable and hot-swappable. You can charge it via the included charging dock or leave the battery in the device and charge it directly using a USB Type-C power adapter (5VDC).
What do the dB values on the screen mean?
+
The dB value represents the Sound Pressure Level (SPL) detected at the current measurement distance. It measures the absolute intensity of the acoustic signal, which is useful for comparing the relative severity of different leaks during an inspection.
Why can I hear a noise, but the camera can't locate it?
+
The camera is optimized for high-frequency and ultrasonic signals (2kHz to 100kHz) where gas leaks and mechanical faults produce their strongest signals. It intentionally filters out low-frequency everyday sounds (below 2kHz) like speech, footsteps, or ambient factory rumble. If you hear a low-pitched sound, it falls outside the detection range.
What frequency range should I use for different applications?
+
Compressed air leaks: 20kHz - 40kHz (Small leak signals peak here with the lowest background noise).
Vacuum / negative pressure leaks: 30kHz - 60kHz.
General inspection / unknown source: 2kHz - 100kHz (Full range scan).
Can the TD2e work in noisy industrial environments?
+
Yes. For noisy environments, you can activate Noise Suppression Mode to filter out background interference and maintain stable acoustic imaging. You can also manually adjust the frequency range to isolate the specific sound of the fault.
What is the detection range and frequency coverage?
+
The effective detection range is 0.3m to 60m. The device covers a frequency range of 2kHz to 100kHz, capturing both the upper end of audible sound and ultrasonic signals.
What's the difference between TD2e Standard and TD2e Kit?
+
The device itself is identical in both versions.
Standard: Includes 1 rechargeable battery and a 1-year warranty.
Kit: Designed for extended field use. It includes 2 batteries (allowing for full-day hot-swapping), a hard carrying case, a portable soft bag, a belt clip, and an extended 18-month warranty.
Can the TD2e detect through walls or underground water pipe leaks?
+
No. The TD2e detects airborne sound waves. Solid barriers like walls or soil block these waves. For concealed water leaks, a FOTRIC thermal imaging camera is a better choice to detect temperature differences caused by moisture. However, if a water pipe is exposed and pressurized water is escaping, the TD2e can detect it.
What kind of leaks and faults can the TD2e detect?
+
The TD2e can detect compressed air system leaks (including valves and fittings), pressurized gas leaks (regardless of gas type), vacuum/negative pressure leaks, and abnormal high-frequency vibrations from loose joints.
