3in1 EMF Detector — combines electric field, magnetic field and radiofrequency measurements in a single compact handheld device with a realtime LCD display for clear radiation level readings. Key features Three measurement modes: electric field, magnetic field and electromagnetic (radiofrequency) detection for comprehensive EMF testing. Wide frequency coverage: detects electromagnetic radiation across a 5Hz–3500MHz bandwidth to identify sources from lowfrequency power to frequency wireless signals. Precise measurement ranges: Electric field: 1 V/m to 1999 V/m Magnetic field: up to 19.99 uT with 0.01 uT resolution Fast, stable readings: integrated electromagnetic sensor and digital processing chip deliver updated results every 0.4 seconds. Clear display: realtime LCD shows numeric values so you can quickly assess levels and compare readings. Operating environment: reliable performance between 0–50 C and under 80% relative humidity. Why you need this device Identify potential EMF exposure points in your home or workplace so you can make informed decisions about placement of beds, desks, and electronic equipment. Verify whether appliances, wiring, or wireless devices are producing elevated electromagnetic fields before committing to longterm use or installation. Quick troubleshooting and verification tool for technicians, property inspectors, or safetyconscious homeowners who need straightforward, measurable data. What makes it stand out Allinone testing: electric, magnetic and RF measurements in one compact tool removes the need to multiple instruments. Accurate and repeatable: builtin sensor plus digital microcontroller provides stable readings every 0.4 seconds for reliable comparisons and trend tracking. Practical frequency coverage: 5Hz–3500MHz captures common household and wireless sources so results reflect realworld exposures. Typical applications Home safety checks: scan bedrooms and living areas to find EMF zones near power lines, fuse boxes, or large appliances and reposition sleeping or working areas accordingly. Appliance and device testing: measure outputs from refrigerators, microwaves, routers, cordless phones and other electronics to see which produce the fields. Onsite inspections: assess EMF levels from power infrastructure, office equipment, or wireless installations during property inspections or maintenance checks. Performance and use notes Readings update every 0.4 seconds; allow the device to stabilize for a few seconds at each measurement point for consistent results. Use the LCD numeric display to record values and compare different locations or devices. Operates effectively within 0–50 C and below 80% humidity; avoid extreme environments for accuracy. This compact, multifunction EMF detector provides clear, reliable measurements of electric fields, magnetic fields and electromagnetic radiation across a broad frequency range, helping users make practical decisions about living and working spaces.
