How Do I Choose the Best EMF Detector?

If you walked into your home or office holding an EMF detector, you’d be pretty alarmed at the levels of electro pollution you’re exposed to every day. You may be thinking, what is electro pollution and what is an EMF detector? Well, electro pollution is the presence of electromagnetic fields in our environment. An EMF detector is what detects and measures these electromagnetic frequencies.

You may also think you are not exposed to these frequencies. Hold that thought. Sources of electromagnetic frequencies include your cell phone, wireless baby monitor, refrigerator, microwave, fluorescent lights, smart meter and even your Wi-Fi. If you’re serious about eliminating electro pollution in your home and office, the first step is to buy an EMF detector. There are many types of EMF detectors on the market with different features and functions.

The type of EMF detector to get depends on the application. The EMF detector to be used in the home for detecting and measuring electromagnetic fields caused by man-made objects will be different from those used by scientists and researchers, especially those interested in natural electromagnetic fields and paranormal research. Each type of detector has its advantages and disadvantages, so each one should be considered carefully before purchase. You should also pay careful attention to the power sources and frequency of the EMF detector.

The aim of this review is to assist you in making the right choice of EMF detectors so you can detect the sources of electro pollution and work toward eliminating them. You need an EMF detector that’s sensitive and accurate enough, with a power source that ensures constant measurement and, of course, the right price.

Price

Price goes a long way in making buying decisions, and it’s often a valid factor. In this case, if you really want to eliminate all electro pollution sources, the features and functions of the EMF detector should be prioritized above the cost.

Usually, the price of EMF detectors ranges between $60 and $180 or even more. An EMF detector that measures magnetic fields, electric fields and radio frequencies will cost more than one that only measures one field. If you also want extra features like audio alarm settings, clock settings and sound output, you will have to pay more. During the course of this research, we came across cheap EMF detectors but we discarded them in our reviews as our intention is to find good value products without compromise.

Features

The wrong EMF detector would leave you frustrated and unhappy. The following are the factors that should be considered when selecting an EMF detector:

Types
Power source
Range
Accuracy
Size/weight
Extras
Resolution

Construction and Design

EMF detectors are of two main types and they are known as the single axis meter and the tri-axis meter. Generally, both measure AC and DC currents, but single axis EMF detectors cost less. Tri-axis meters measure all three dimensions at once. This means the tri-axis detector is faster at taking sample readings. It also offers an increased range of sensitivity that the single axis detector. Apart from that, the tri-axis detectors provide more accurate readings and offer more features.

An EMF detector is usually powered by batteries but there are some that can also be powered via USB connection and an external power supply. Depending on the battery used, some detectors last for up to 100 hours, while others can go up to 6 months of frequent use and 12 months of normal use. To avoid running out of power, we advise you keep spare batteries.

The range, frequency, accuracy and resolution of an EMF detector depend on its brand and application. Applications such as detection of microwave leaks and circuit breaks will require an EMF detector with a high frequency and range, say from 40Hz to 100KHz. But in cases where you have to measure magnetic and electric fields that originate from cell phones and small home appliances, you will need an EMF detector that can measure extremely low bandwidths of about 30Hz to 300Hz. In terms of accuracy, a tri-axis EMF detector is quite accurate, same as a digital detector. The analog needle types and the single EMF detectors tend to be less accurate. Also, some EMF detectors have an extremely high frequency. This can be useful to those interested in paranormal research.

Performance and Ease of Use

There are additional features that usually enhance the performance and ease of use of an EMF detector. A typical example is the presence of a colored LCD screen. Different EMF detectors have different means of displaying readings but a meter with a 4 inch or more screen makes it easier. Some come with LED lights which light up as soon as you encounter electro pollution. These LED lights also allow you to see clearly in dark and low light conditions.

The type of material determines how durable an EMF detector will be. Most of them are made from ABS plastic and are rugged and impact resistant. Others come with a padded pouch for easy portability and storage. Another factor that affects portability is size. Most EMF detectors are small and lightweight. They can fit into the hand, pocket and purse. Hence, they can be carried anywhere without breaking a sweat.

Other features include an On/Off switch to avoid battery wastage, a low battery indicator, an audio alarm setting and a normal clock setting. Some EMF detectors have a buzzer that goes off when you encounter an electromagnetic field; these buzzers can sometimes be turned off if noise jeopardizes your investigations.

What is the Best EMF Detector?

From our buying guide, you already know that EMF detectors have different types, sizes, resolutions and frequencies – some extremely low, others high. The following individual product reviews highlight different EMF detectors and the functions they offer. Since you’ve read the guide, we believe you now have a basic knowledge of EMF detectors and selection should be a lot easier. So, let’s dig into the individual product reviews.
