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.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003eWhile 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.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cspan\u003e• \u003c\/span\u003eIt can be widely used in government, public security, prison, justice, army, education examination, business security and personal privacy protection, etc.\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eBusiness Safety: Detecting unauthorized electronic devices, such as eavesdroppers, mobile phones and devices with SIM cards, hidden in company boardrooms or secret offices.\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003ePublic Safety: Detecting electronic devices hidden or prohibited from use in safe areas, such as detonators, remote controllers, etc.\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003ePersonal Privacy Protection: Hidden cameras and surveillance devices such as recording pens, cameras, etc. in residential buildings and hotels.\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eCompetitive advantages\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eUltra-small size and weight\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eHigh detection sensitivity\u003c\/div\u003e\n\u003cdiv\u003e• Enchanced audio demodulation channel\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eOptimized response in false electronics indication\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eSupports harmonic amplitude time domain curves and audio analysis functions\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eStrong environmental adaptability and stable operation in various environments\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eGood ergonomic design makes it easy to hold and work in long operations\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e\n\u003cstrong\u003eTechnological advantages\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eAdopts NLJD technology to determine the degree of non-linearity of the target object\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eAdopts the harmonic time axis waveform display and audio demodulation to determine junction type of the target object\u003cbr\u003e\u003cspan\u003e• \u003c\/span\u003eUtilizes high-gain, high-concentric, circularly polarized antenna to optimize performance\u003c\/div\u003e\n\u003cdiv\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003ctable class=\"laurea\" border=\"0\" cellspacing=\"1\" cellpadding=\"3\"\u003e\n\u003ctbody\u003e\n\u003ctr class=\"head\"\u003e\n\u003ctd colspan=\"2\" align=\"center\"\u003e\u003cspan\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd width=\"50%\"\u003eTransmitting Frequency range\u003c\/td\u003e\n\u003ctd width=\"50%\"\u003e2.404 GHz -
