Non Linear Junction Detector for Sale

Sensitivity & harmonic coverage: Look for models that detect both 2nd and 3rd harmonics (important for modern electronics) and with high sensitivity (e.g., ‑130 dBm or better).

Transmit power & frequency band: Higher probing power and wider frequency band may mean better penetration and detection behind materials/shields.

Physical form & portability: Weight, size, pole/extension capability (for ceilings), ease of use in tight spaces.

User interface & data logging: Screens, audio/vibration alerts, reporting/logging features are useful if you’ll use it in professional sweeps.

Durability & service support: Calibration, spare parts, software updates — especially important if you’re operating in Pakistan/South Asia with hot/humid conditions.

Regulatory / export compliance: Some NLJDs may be subject to export control or import licences depending on country and capability; check local regulations.

Budget vs mission requirements: High‑end models cost significantly more—ensure spec matches your need (e.g., corporate TSCM vs simple office checks).
