ERICKHILL RT-100S 3-in-1 EMF Detector

Description

The ERICKHILL RT-100S EMF detector combines electric-field, magnetic-field, and radio-frequency measurements in one rechargeable handheld meter. For paranormal investigators, its main advantage is that it separates three common sources of electromagnetic activity instead of reducing every change to a single unexplained spike.

ERICKHILL RT-100S features at a glance

• Three measurement modes: displays electric fields (EF), magnetic fields (MF), and radio-frequency fields (RF).
• Simultaneous readings: shows the three field types on one screen so you can identify which measurement is changing.
• Color-coded display: uses green, orange, and red screen states to make threshold changes easier to see in dim locations.
• Multiple alerts: provides screen, light, and audible warnings; the sound can be disabled when a quiet session matters.
• Rechargeable design: charges through USB-C and includes an automatic shutoff feature to conserve power.
• Portable format: fits easily into a field bag and can be operated without a complicated setup process.

How it fits into a paranormal investigation

At the start of a session, use the RT-100S to record normal readings around outlets, wiring, breaker panels, appliances, radios, phones, Wi-Fi equipment, and other electronics. Those baseline measurements make later changes easier to interpret. If the meter reacts, switch between the displayed field types and check nearby equipment before treating the reading as unusual.

The RT-100S can be especially useful in buildings where several kinds of electromagnetic interference overlap. A rise in RF may point toward a phone, wireless camera, radio, or router. An EF or MF change may be associated with wiring, transformers, motors, or powered equipment. Separating those channels gives an investigator more context than a simple light-only detector.

An EMF change is not proof of paranormal activity. The meter measures electromagnetic fields, not spirits. Use it as an environmental instrument, document the time and location of each change, and compare the result with audio, video, temperature, and witness notes. Our guide to using an EMF meter for ghost hunting explains how to establish a baseline and rule out ordinary interference.

What to consider before buying

The ERICKHILL RT-100S is a practical choice when you want EF, MF, and RF information in one affordable handheld device. Its color display and alarms make it approachable for a beginner, while the separate measurements are useful for investigators who want more context than a basic five-light meter provides.

It is not a data-logging instrument, and it should not replace professional calibrated equipment when precise occupational or electrical testing is required. Field accuracy also depends on how steadily you hold the meter, your distance from a source, and whether nearby phones or radios are transmitting. Repeat a reading from several positions before drawing a conclusion.

ERICKHILL RT-100S FAQ

What does the ERICKHILL RT-100S measure?

It measures electric fields, magnetic fields, and radio-frequency fields. The three readings help distinguish between different types of nearby electromagnetic sources.

Can the RT-100S be used for ghost hunting?

Yes, it can be used to document environmental EMF changes during a paranormal investigation. A spike should always be checked against wiring, appliances, phones, radios, Wi-Fi equipment, and other normal sources.

Does it identify the source of a reading?

No. It reports field strength but does not name the device or cause. Investigators still need to move through the area, turn known equipment off when safe, and repeat the measurement.

Is the ERICKHILL RT-100S rechargeable?

Yes. The model uses USB-C charging. Confirm the current package contents, warranty, price, and availability with the retailer before ordering.
