DT-824S - Compact Non Linear Junction Detector

$16,875.00
DT-824S is a latest NLJD model of detectors series DT with latest technology and software integrated. It can detect electronic devices hidden in walls, floors, ceilings, lamps, furniture or containers, switched on or off, by display, sound and vibration.
DT-824S is an advanced handheld nonlinear junction detector(NLJD) with compact design, released in 2025. It adopts self-developed nonlinear harmonic technology, combined with non-destructive detection and a precise phase algorithm. This NLJD also supports time-domain harmonic peak mode and harmonic audio mode functionality, giving better analysis of the target items. It can detect any electronic devices concealed in packages, walls, floors, ceilings, lamps, furniture, or containers, regardless of whether the devices are powered on or off, emitting signals or not. DT-824S is ideal for a wide range of applications, including electronic explosive detection, confidentiality inspections, and identifying prohibited items in correctional facilities.
 
While most handheld NLJDs in the market offer a standard sensitivity of -110dBm to -125dBm, this device was engineered to a higher professional standard. By achieving a receiver sensitivity of -140dBm, the DT-824S provides operators with a significantly enhanced detection capability. This allows for the reliable identification of smaller, more distant, or well-shielded electronic devices, ensuring a more thorough and dependable security sweep.
 
Application
• It can be widely used in government, public security, prison, justice, army, education examination, business security and personal privacy protection, etc.
• Business Safety: Detecting unauthorized electronic devices, such as eavesdroppers, mobile phones and devices with SIM cards, hidden in company boardrooms or secret offices.
• Public Safety: Detecting electronic devices hidden or prohibited from use in safe areas, such as detonators, remote controllers, etc.
• Personal Privacy Protection: Hidden cameras and surveillance devices such as recording pens, cameras, etc. in residential buildings and hotels.
 
Competitive advantages
• Ultra-small size and weight
• High detection sensitivity
• Enchanced audio demodulation channel
• Optimized response in false electronics indication
• Supports harmonic amplitude time domain curves and audio analysis functions
• Strong environmental adaptability and stable operation in various environments
• Good ergonomic design makes it easy to hold and work in long operations
 
Technological advantages
• Adopts NLJD technology to determine the degree of non-linearity of the target object
• Adopts the harmonic time axis waveform display and audio demodulation to determine junction type of the target object
• Utilizes high-gain, high-concentric, circularly polarized antenna to optimize performance
