K2 EMF Meter — 5-LED Electromagnetic Field Detector

K2 EMF Meter

The K2 is a simple, popular EMF meter that shows electromagnetic field strength on an easy-to-read 5-LED scale. It's widely used to survey appliances and wiring for higher-emission spots, and it's a long-time favorite among paranormal-investigation hobbyists too.

How the 5-LED scale reads

• LED 1: normal ambient EMF (0–1.5 mG)
• LED 2 (green): low (1.5–2.5 mG)
• LED 3 (yellow): mid (2.5–10 mG)
• LED 4 (orange): high (10–20 mG)
• LED 5 (red): very high (20+ mG)

Specifications

• Detection range: 0 to 20+ milliGauss
• Frequency: 30 Hz – 20,000 Hz
• Accuracy: ±5%
• Material: ABS · Size: 14.3 × 5.2 × 2.5 cm · Single-battery, push-on/off operation

This is a measuring instrument, not a shielding product — it detects and displays field levels so you can survey your environment. It does not block or reduce EMF, and readings are for general awareness, not medical assessment.
