Quick answer: The ERICKHILL RT-100 is a good starter EMF meter for ghost hunting if you want a rechargeable device with a readable LCD, numerical electric- and magnetic-field measurements, data hold, average/peak modes, and adjustable sound alerts. It does not measure radio-frequency fields, and no EMF reading by itself proves paranormal activity.
Why the ERICKHILL RT-100 is a good EMF meter for ghost hunting
A useful investigation meter should do more than create a dramatic reaction. It should help you establish a baseline, identify ordinary electrical interference, and document changes in a way you can review later. The RT-100 is attractive for beginners because it combines straightforward controls with actual numbers on a backlit screen.
According to ERICKHILL’s published specifications, the RT-100 measures AC electric fields in volts per meter and magnetic fields in microtesla or milligauss. It can display both field types at the same time, sample about every 0.4 second, and store a reading with its data-hold function. Those features make it more useful for methodical room sweeps than a device that only lights up without showing a value.
1. Numerical readings help you build a baseline
Before an investigation begins, walk through the location and record the normal readings in each room. Check walls, outlets, breaker panels, appliances, security systems, extension cords, and powered equipment. When you know what the room normally looks like, a later change has context.
The RT-100’s LCD lets you record specific values rather than writing “the meter went off.” That difference matters. A number can be compared with a previous reading, matched to a timestamp, and checked again from the same position.
2. Rechargeable power is convenient in the field
The RT-100 uses a built-in 3.7-volt lithium battery and comes with a USB charging cable. Rechargeable power is helpful for investigators who use their meter regularly and do not want to keep disposable batteries in every gear case. The automatic shutoff feature also helps conserve power when the meter is left idle.
Charge it before leaving for a location and carry a compatible power bank or charging cable as backup. Avoid charging the meter during an active session because the cable and nearby electronics can introduce another possible source of interference.
3. Peak, average, hold, and alarm functions are useful
The average and peak modes give you two ways to look at a changing environment. Average mode can help you understand the general field level in a room, while peak mode can preserve the highest detected value during a sweep. The hold button is useful when you need to move into better light or show another investigator the reading.
The meter also uses visual and audible warnings. ERICKHILL lists alarm thresholds of 40 V/m for electric fields and 0.4 µT, or 4 mG, for magnetic fields. You can mute the buzzer for quiet EVP sessions while continuing to watch the display.
Important: Those alarm thresholds are device settings, not a boundary between ordinary and paranormal activity. Wiring, appliances, phones, radios, power supplies, and many other everyday sources can trigger a meter.
What the RT-100 does—and does not—measure
| Capability | RT-100 support | Why it matters in an investigation |
|---|---|---|
| AC electric field | Yes, displayed in V/m | Helps locate fields around wiring and powered equipment. |
| Magnetic field | Yes, displayed in µT or mG | Provides numerical readings for baseline sweeps and repeat checks. |
| RF measurement | No | It will not separately measure Wi-Fi, cellular, or radio-frequency signals. |
| Peak and average modes | Yes | Useful for spotting brief changes and comparing typical field levels. |
| Data hold | Yes | Locks a displayed reading so it can be logged or photographed. |
| Sound and visual warning | Yes | Makes threshold crossings easier to notice; sound can be muted. |
The lack of RF measurement is the biggest limitation to understand. Phones, walkie-talkies, wireless cameras, Bluetooth devices, and Wi-Fi equipment can complicate an investigation. The RT-100 can help with electric- and magnetic-field checks, but it cannot tell you the RF level. Investigators who need broader environmental analysis may prefer a multi-axis or tri-field meter that explicitly measures radio frequencies.
How to use the ERICKHILL RT-100 during a ghost hunt
- Charge and test the meter at home. Learn how the display, units, peak mode, hold button, and buzzer work before arriving at a dark location.
- Reduce avoidable interference. Put nonessential phones in airplane mode, move radios and power banks away from the test area, and note any equipment that must remain active.
- Perform a baseline sweep. Walk each room slowly. Record readings near outlets, walls, appliances, breaker panels, lighting, and security equipment.
- Mark known hotspots. A high reading beside a refrigerator or electrical panel is environmental context, not a mystery.
- Keep the meter position consistent. Distance and orientation can change the reading. During a controlled session, place the device in one documented position.
- Log the time and value. If the reading changes, note the exact time, displayed units, location, nearby equipment, and what the team was doing.
- Try to reproduce the result. Repeat the same movement or question, remove nearby electronics, and check the area from multiple angles.
- Compare with other records. Review audio, video, temperature notes, and witness observations. Treat an unexplained spike as one data point, not a conclusion.
Is the ERICKHILL RT-100 better than a K-II meter?
It depends on how you investigate. A K-II-style meter is popular because its colored LED scale is easy to see on camera and simple to use during live-response sessions. The trade-off is that an LED ladder gives less measurement detail than a numerical display.
The RT-100 is the stronger choice if you want to write down electric- and magnetic-field values, compare rooms, and document peak readings. A K-II may be more convenient when fast visual feedback is the priority. Some teams use a numerical meter for the baseline sweep and a simple visual meter during a stationary session.

Who should choose the ERICKHILL RT-100?
The RT-100 is a sensible fit for:
- Beginners building their first paranormal investigation kit
- Hobbyists who want numbers instead of lights alone
- Investigators who need a compact rechargeable meter
- Teams performing pre-investigation electrical baseline sweeps
- Users who value peak, average, and data-hold functions
You may want a different meter if you need RF measurement, data logging to a computer, multi-axis analysis, or a device designed specifically for on-camera trigger sessions. The best tool is the one that matches your method and whose behavior you understand well enough to recognize ordinary interference.
Common EMF meter mistakes to avoid
Treating every spike as paranormal
EMF meters respond to electromagnetic fields, not ghosts. An unusual reading deserves investigation, but nearby wiring, a phone, a radio, an appliance, or another team member’s equipment may be the cause.
Skipping the baseline sweep
Without a baseline, you do not know whether a reading is new or normal for the building. Map the environment before beginning EVP questions or other active sessions.
Moving the meter too much
Small changes in distance can create large changes in field strength. Keep the meter stationary when testing whether an event is repeatable.
Forgetting to document the units
A number without its unit is incomplete. Record whether the reading is V/m, µT, or mG so it can be interpreted correctly later.
Frequently asked questions
What is a good EMF meter for a beginner ghost hunter?
The ERICKHILL RT-100 is a good beginner option for investigators who want rechargeable power, a clear numerical display, electric- and magnetic-field measurement, peak and average modes, and data hold. It is easy to learn but still supports a more disciplined baseline process.
Can the ERICKHILL RT-100 detect ghosts?
No device can verify that a ghost caused an EMF reading. The RT-100 detects electric and magnetic fields. Paranormal investigators may use unexplained changes as clues to document and investigate, but ordinary sources must be ruled out first.
Does the ERICKHILL RT-100 measure radio frequencies?
No. The manufacturer states that the RT-100 does not test RF values. If RF measurement is important to your investigation, choose a meter that specifically includes radio-frequency detection.
Should I use peak or average mode?
Use average mode to understand the typical field level in an area. Use peak mode when you want to capture the highest reading during a sweep. For stronger records, note which mode was active every time you log a value.
Final verdict: Is the ERICKHILL RT-100 a good choice?
For a new investigator asking what’s a good EMF meter for ghost hunting, the ERICKHILL RT-100 is a practical starting point. Its numerical display, rechargeable battery, dual electric- and magnetic-field readings, alarm, and hold functions support more careful fieldwork than a lights-only novelty device.
Its main limitation is the lack of RF measurement, and it should never be treated as a ghost detector. Used correctly—as a baseline and environmental-monitoring tool—it can help you reduce false positives and create better investigation notes.
