More Details
Main highlights
- 【Versatile Scene Applications: Automotive, Home Appliances, Daily Life】The TD2e helps you quickly locate the source of annoying noises: in cars, pinpoint abnormal sounds from engines, suspension, or interior trim rattles; in home appliances, detect buzzing, clicking, or vibrating parts from refrigerators, washing machines, or HVAC units; in daily life, find hidden noise sources like a leaking pipe joint under a sink or a loose window seal. Simply point, shoot, and see the sound source as a real-time photo, no more guesswork.
- 【Professional Grade Features : Dual Detection & Multiple Image Modes】The FOTRIC TD2e is built for real-world industrial environments. Noise Reduction Mode maintains stable acoustic imaging even in high-noise factories, accurately locating true sound sources without false readings. Micro-Detection Mode captures the faintest ultrasonic leaks or vibrations that other devices miss. Plus, choose from Single-source, Multi-source, and All-source image modes, so whether you're tracking one leak, multiple simultaneous issues, or everything in your field of view, you get clear, actionable visual results instantly.1-year warranty for the whole unit.
- 【High-Resolution Touch Screen & Portable Durable Design】The 3.5" high-resolution IPS touchscreen (640×480) with explosion-proof cover glass protection allows you to instantly overlay sound pressure data on visible-light images for faster diagnostics. Lightweight at just 720g and rugged with IP54 rating and 2m drop resistance, the FOTRIC TD2e acoustic imager includes a 5000mAh rechargeable battery for 3+ hours of continuous operation, ideal for field inspections in industrial, HVAC, or energy sectors.
- 【Detect Compressed Air, Vacuum & Pneumatic Valve Leaks, Vibration Problems】Quickly locate costly leaks in compressed air systems, vacuum chambers, pneumatic valves, cylinders, and fittings. Additionally, identify abnormal vibrations from loose joints, bearing wear, or structural looseness on running equipment. The FOTRIC TD2e acoustic imaging camera visualizes high-frequency turbulence noise and vibration-induced ultrasound as a clear photo, helping you reduce energy waste, prevent unplanned downtime, and avoid mechanical failures.
- 【64 MEMS Digital Microphone Array & Beamforming Algorithm】Equipped with 64 high-sensitivity MEMS microphones, the TD2e acoustic camera captures both audible sound and ultrasonic signals (2kHz–100kHz). The advanced beamforming algorithm isolates sound sources from noisy environments, generating a real-time acoustic photo overlaid on a 5MP optical image. Detect leaks that human ears cannot hear.
