FOTRIC Launches TD2eGeek Smartphone Acoustic Imager — Acoustic Imaging. Now in Your Pocket
What if the your smartphone could help you see sounds you can't hear?
Sound is everywhere.
Escaping from compressed air lines. Traveling through mechanical equipment. Generated by electrical discharge. Leaking from HVAC systems. Revealing air-tightness problems in vehicles and manufacturing processes.
But not every sound can be heard.
The human ear typically perceives frequencies from 20 Hz to 20 kHz, while hidden faults such as gas leaks and electrical discharge can generate ultrasound beyond the range of human hearing. Acoustic imaging turns these otherwise invisible sound sources into visual information, helping users see where the sound is coming from.
Meet the FOTRIC TD2eGeek Smartphone Acoustic Imager—a compact acoustic imaging device that transforms a compatible Android smartphone into a portable tool for visualizing and locating sound sources.
Small enough to carry with you and simple enough for everyday inspection, TD2eGeek puts acoustic imaging right in your pocket.
Empower Your Phone with Acoustic Vision
TD2eGeek transforms sound into visual acoustic images on your smartphone, helping technicians locate acoustic sources that may be difficult—or impossible—to identify by hearing alone.
Simply connect TD2eGeek to your Android smartphone, open the FOTRIC app, and start inspecting.
Plug in. Scan. Locate. Capture. Share.
Acoustic imaging becomes part of the device already in your pocket.
Pocket-Sized Freedom
The best inspection tool isn't always the biggest one.
Sometimes, it's the one that's always within reach.
At just 200g, TD2eGeek fits easily into a pocket, toolbox, or work bag, ready for routine maintenance rounds and quick troubleshooting. Its compact design makes it easy to carry from one inspection point to the next.
Instead of reserving acoustic imaging for planned inspections, technicians can bring it along as part of their everyday toolkit.
Small enough to carry. Ready when there's something to find.
Small Size. Serious Acoustic Imaging.
Compact doesn't mean limited.
TD2eGeek brings together the essential capabilities needed for acoustic inspection across a variety of industrial environments.
64 Microphones
A 64-channel microphone array captures acoustic information and helps visualize and locate sound sources during inspection.
2–100 kHz Adjustable Frequency Range
Move from audible sound to ultrasound with a manually adjustable 2–100 kHz frequency range, supporting applications from mechanical fault diagnosis to gas leak and partial discharge detection.
≥4 Hours Battery Operation
With 4 hours or more of continuous operation, TD2eGeek is ready for routine inspection rounds and extended field use.
5 MP Industrial-Grade Digital Camera
A 5 MP industrial-grade digital camera provides clear visual context alongside acoustic imaging, helping users identify equipment and document inspection findings.
Find Compressed Air & Vacuum Leaks You Can't Hear
One of the key applications for TD2eGeek is compressed air and vacuum leak detection.
Industrial leaks can generate ultrasonic signals that are difficult to identify through ordinary listening, particularly in noisy operating environments.
TD2eGeek turns these signals into visual acoustic images on your smartphone, helping technicians locate where the sound is coming from. Its adjustable frequency range allows users to focus on relevant ultrasonic signals while reducing interference from surrounding noise.
The workflow is simple:
Walk. Scan. Locate. Document.
By combining portability with acoustic visualization, TD2eGeek makes it easier to bring leak detection into routine maintenance rather than limiting acoustic imaging to occasional specialized surveys.
One Pocket Device. Multiple Industrial Applications.
Compressed air and vacuum leak detection is only the beginning.
TD2eGeek supports acoustic imaging across a range of industrial inspection and troubleshooting scenarios.
Mechanical Equipment Fault Diagnosis
Locate abnormal sounds from operating machinery to support routine inspection and troubleshooting.
Partial Discharge Inspection
Visualize acoustic emissions associated with electrical discharge and help locate potential problem areas.
HVAC Air Leak Inspection
Scan HVAC equipment and systems to identify acoustic sources associated with air leakage.
Vehicle Air Tightness Inspection
Locate air-leak sources during vehicle air-tightness testing and troubleshooting.
Manufacturing Line Quality Inspection
Bring portable acoustic imaging into manufacturing environments to locate abnormal sound sources and support quality inspection.
From maintenance and reliability to manufacturing and automotive applications, TD2eGeek gives technicians a portable way to see where sound is coming from.
From Detection to Documentation
Finding a problem is only part of an inspection. The finding also needs to be captured and communicated.
TD2eGeek supports image and video capture, while acoustic images, videos, and reports can be shared through its smartphone-based workflow.
Technicians can locate an acoustic source, capture inspection evidence, and share their findings—all from the smartphone in their hand.
Locate the problem. Capture the evidence. Share the finding.
The Acoustic Imager You'll Actually Carry
Acoustic imaging has often been treated as a specialized inspection technology.
TD2eGeek is built around a simpler idea: make acoustic imaging easy enough to carry and use as part of everyday maintenance.
Whether you're walking a compressed air line, investigating an unusual machine sound, checking electrical equipment, or troubleshooting an HVAC system, TD2eGeek is ready to go wherever the next inspection takes you.
Portable enough for everyday inspection. Capable enough to find what you can't hear.
See the Sound. Anytime. Anywhere.
The FOTRIC TD2eGeek Smartphone Acoustic Imager brings acoustic imaging to the Android smartphone already in your pocket—making it easier to visualize, locate, and document sound sources whenever an inspection task arises.
From routine maintenance rounds to unexpected troubleshooting, TD2eGeek gives technicians a more portable way to see what their ears alone may not reveal.
Acoustic imaging, ready when you are.
Empower Your Phone with Acoustic Vision.
