View Technical Specifications

Using an array of 64 digital MEMS microphones, the device collects acoustic information from multiple directions and transforms it into a visual representation, helping users locate sound sources that may be difficult or impossible to identify by hearing alone.

Weighing only 200 g, the TD2eGeek is designed for routine inspections, maintenance, rapid diagnostics and field work where portability is essential.

See Sound Directly on Your Smartphone

Connect the TD2eGeek to a compatible Android smartphone, use the FOTRIC application and transform acoustic signals into images that help quickly locate the source of the sound. The workflow becomes simple: connect, search, locate, record and share.

Acoustic Imaging – Make the Unheard Visible

The human ear detects only part of the sound spectrum. Many leaks, electrical discharges and mechanical anomalies can produce ultrasonic components above the range of human hearing.

The TD2eGeek covers a wide range from 2 kHz to 100 kHz, enabling inspection from audible sounds through to ultrasonic frequencies used for locating certain industrial anomalies.

Plug-in and Shoot

64 MEMS Microphones for Acoustic Source Localisation

The 64-channel microphone array captures acoustic information from different directions to help determine the location of sound sources during inspection.

Acoustic field of view: 58° × 45°

Frame rate: 15 Hz

Sampling rate: 200 kHz

Adjustable Frequency Range from 2 to 100 kHz

The frequency range can be adjusted according to the application, allowing the inspection to focus on the most relevant acoustic band while reducing the influence of unwanted sound sources.

Professional Acoustic Imaging

Audible – investigation of noise and mechanical anomalies

Ultrasound – locating leaks and specific high-frequency emissions

Custom – manual selection of the frequency range required for the inspection

Main Applications of the FOTRIC TD2eGeek

Compressed Air Leaks
Locate acoustic sources associated with leaks in pneumatic systems, pipes, fittings, valves and equipment.

Vacuum Leaks
Support the identification of leaks in vacuum systems and associated connections.

HVAC
Locate sound sources associated with air leaks in equipment, ductwork and HVAC systems.

Mechanical Equipment Diagnostics
Locate abnormal noises generated by machinery during operation.

Partial Discharge
Visualise acoustic emissions associated with electrical discharge phenomena, helping locate potential problem areas.

Manufacturing Quality Control
Search for abnormal sound sources in production lines and manufacturing processes.

Vehicle Air-Tightness Testing
Support the localisation of leakage points during air-tightness tests.

From Detection to Documentation

The TD2eGeek is not limited to locating an acoustic source. The solution supports image and video capture, allowing inspection results to be documented directly in the field.

Smartphone integration also makes it easier to share images, videos and reports, simplifying communication between technicians, maintenance teams, engineers and facility managers.

Multiple Acoustic Imaging Modes

Single Source – highlight a single sound source

Multiple Source – visualise multiple sound sources

Hologram Mode – acoustic visualisation adapted to more complex scenarios

Compact for Everyday Inspections

With dimensions of only 101 × 77 × 22 mm and an approximate weight of 200 g, the TD2eGeek can be easily carried in a tool case or inspection kit.

Continuous operation of 4 hours or more is suitable for maintenance rounds and field inspections, while the ergonomic handle includes anti-slip components.
