Product Overview The 3-in-1 Multifunctional Electromagnetic Radiation Detector is a handheld EMF meter that measures three field types from a single sensor head — electric field (V/m), magnetic field (mG / µT) and radio frequency radiation (mW/m²). The unit is built for everyday users monitoring household and workplace EMF exposure across the 50 Hz to 3,500 MHz band, with a backlit display, peak-hold mode and three configurable threshold alarms (safety, alert, avoidance). An ergonomic body with soft rubber keys, anti-slip textured sides and a wear-resistant base pad makes the meter comfortable for extended use. Automatic shutdown after 15 minutes of inactivity preserves battery life and can be disabled when continuous monitoring is required. Key Features Triple detection: Electric field, magnetic field and RF radiation from a single sensor head High-precision sensor: Built-in electromagnetic radiation sensor driven by a micro-controlled chip processor Digital display with automatic alarm: Backlit large screen with sound, light and on-screen alerts when readings exceed configured thresholds Unit switching: Toggle magnetic field readings between mG (milligauss) and µT (microtesla) Peak-hold mode: Captures the maximum field strength seen during a measurement window Ergonomic design: Soft rubber keys, anti-slip textured sides and a wear-resistant base pad Automatic shutdown: After 15 minutes of inactivity (can be disabled for long monitoring sessions) Technical Specifications Measurement Ranges Bandwidth: 50 Hz – 3,500 MHz Electric field (EF): 1–1,999 V/m (sensitivity 1 V/m) Magnetic field (MF): 0.1–999.9 mG / 0.01–99.99 µT RF power density: 0.01–19.99 mW/m² Accuracy: ±5% Alarm Thresholds Safety: EF < 40 V/m, MF < 4 mG, RF < 5 mW/m² Alert: EF 40–80 V/m, MF 4–8 mG, RF 5–10 mW/m² Avoidance: EF > 80 V/m, MF > 8 mG, RF > 10 mW/m² Physical and Environmental Battery: 1 × 9 V (not included) Operating temperature: -10°C to 60°C (14°F to 140°F) Operating humidity: < 80% RH Dimensions: 147 × 68.5 × 28 mm (5.8" × 2.7" × 1.1") Weight: 132 g (4.7 oz) Applications Assessing EMF emissions from home appliances, smart meters and Wi-Fi access points Power distribution rooms and switchboards Surveying around high-voltage towers and overhead lines Electric vehicle cabins and charging environments High-speed train stations, signal towers and radio equipment installations Spot-checking 5G and other RF transmission sources What's in the Set 1 × Electromagnetic Radiation Tester 1 × Protective cloth bag 1 × User manual
