  • 3-in-1 Emf Meter: Neoteck EFM detector can simultaneously measure 3 types of electromagnetic pollution on one screen: electric field (EF), magnetic field (MF), and radio frequency (RF) radiation. It features a measurement accuracy of ±5% and different pollution have different measurement ranges and sensitivities, EF (1-1999 V/m, 1 V/m sensitivity), MF (0.1-999.9 mG / 0.01-99.99μT, 0.1 mG / 0.01μT sensitivity),and RF (0.1-999.9 mW/m²/ 0.01-99.99μW/cm², 0.1 mW/m²/0.01μW/cm² sensitivity)
  • 3-Axis Magnetic Field Detection:Neoteck EMF detector features X, Y, Z magnetic field sensing capability,measuring the magnetic field components along 3 spatial axes. The X-axis represents the width direction of the detector, the Y-axis corresponds to its height direction, and the Z-axis is perpendicular to the detector's screen. The EMF meter allows you to identify the strength of the magnetic field and determines its direction, ideal for professional electrical engineers and inspectors
  • Visual & Audio Alarm:The EMF radiation meter is equipped with a tricolor LED indicator (green, blue, red) and a buzzer, providing immediate feedback on radiation levels. It automatically triggers an alarm when exceeding safety thresholds: EF (250 V/m), MF (5μT/50 mG), or RF (50 mW/m²/5μW/cm²). As the indicator light transitions from green to red, the buzzer emits increasingly rapid "BEEP" sounds. Even in noisy or visually busy environments,allowing for effortless detection of pollution
  • Intelligent Recognition: The radiation detect or can identify 3 types of RF signals and display relevant information on its backlit LCD screen. When a Wi-Fi transmission source is detected, the screen shows "WIFI/PHONE"; when the source is a microwave, it displays "MICROWAVE*"; and for mixed signals, it shows "MIXED".This EMF reader distinguishes common radiation sources, enabling more targeted and effective electromagnetic radiation management in your daily environment
  • Long Battery Life: Neoteck EMF detector is equipped with a 1200mAh rechargeable battery, a Type-C charging port. The screen features a battery level indicator, allowing you to monitor the remaining power at any time. It also includes a 15-minute auto-shutdown function to conserve energy when not in use. If continuous measurement is required, simply press and hold the "APO" button to disable the auto-shutdown feature

Product Description

3-in-1 EMF Meter for Home, Work & Investigation

Portable EMF Detector

Neoteck EMF detector is essential for everyone. Homeowners check appliance safety, engineers map fields, and investigators (including paranormal teams) rely on its accuracy. It's your all-in-one tool for identifying electric, magnetic, and RF radiation sources.

3-Axis Magnetic Field Detection for Precise Analysis

Magnetic Field Detector

Locate and analyze magnetic fields with precision. This detector measures field strength along X, Y, and Z axes, revealing both intensity and direction. It's the professional choice for diagnosing issues and pinpointing sources.

Simultaneous 3-Type EMF Detection: EF, MF & RF

EMF Meter

See all EMF pollution at once. EMF meter simultaneously measures Electric Fields (EF), Magnetic Fields (MF), and Radio Frequency (RF) radiation with high sensitivity. Get a complete picture of your environment's electromagnetic levels on one clear screen.

Instant Visual & Audio Alerts for EMF Safety

EMF Detector

Get clear warnings instantly. A tri-color LED and buzzer activate when readings exceed safe thresholds. The light turns from green to red and beeps speed up as radiation increases, ensuring you never miss a critical alert.

Long-Lasting Battery with Auto-Off & Data Hold

Magnetic Field Detector

Built for convenience. The 1200mAh USB-C battery lasts for extended use. The 15-minute auto-shutdown saves power, and the HOLD function locks readings. A clear backlit screen ensures easy viewing in any light.
