EMF Meter Electromagnetic Field Radiation Detector-Handheld Digital LCD Backlight EMF Detector for Home Office Outdoor Inspection with Sound-Light Alarm-Silver

【MAKE LIFE MORE SAFE & COMFORT】-You can’t see, smell, taste, feel, or hear electromagnetic fields (EMF) but make no mistake they are there. Selavif EMF Meter friendly for fresh and advanced users. This meter is super intuitive and simple to use. Just get closer to the electromagnetic radiation source and test..
【ONE-HANDED OPERATION & HIGH SENSITIVITY】- One-handed operation, easy to move for on-site measurements, effectively identify the signal source and locate the signal position.
Although Selavif EMF Detector is compact and light, it is still high sensitivity. Radiation assessment is equipped with a built-in magnetic radiation sensor to display the radiation value on the digital LCD screen after processing by control micro-chip.
【AUTO SOUND-LIGHT ALARM & ONE TOUCH LOCK RADIATION】- Selavif EMF Meter is built-in signal strength prompt speaker, and will trigger sound-light alarm when the radiation data exceeds the safe range (Electric field 003e 40 V/M and Magnetic field003e 0.4µT)-the detector will flash red and alert the user via an alarm sound automatically.
Long press the “BEEP” can turn off the sound. Data retention to lock Max/Average value by one key.It is a good helper to check out whether the place is radiation-free.
