Measurement of electric and magnetic fields in this price range has never been this PROFESSIONAL.
Find radiation sources in your surroundings. Find their respective frequencies and signal strengths, including direct display of exposure limits. This used to be impossible in this price category, professional units often costing several thousand euros and being excessively complicated in handling.
The highly complex calculations in spectrum analysis incl. exposure limit calculation is being performed, unnoticed in the background, by a high-performance DSP (digital signal processor). This ultra-fast processor even allows, depending on the settings, REAL-TIME display with a NF-5030 (could you ask for more?). Simply amazing!

Fast, handy, cost-effective, beautiful exterior and PRECISION - what more could you ask ?

Affordable PRO measurement equipment: SPECTRAN® 10xx

Professional EMF measurement devices use a frequency dependant measurement approach, the so-called spectrum analysis. In a certain frequency range, the individuals signals and their respective strengths are being broken down, for example into a "bargraph" display (see SPECTRAN® screenshot on the right). The height of the individual bars represents the corresponding signal strength. For the 3 strongest signal sources, SPECTRAN® can automatically displays the frequency and signal level, thanks to its "Auto Marker" feature. Of course, you can also setup the filter width and the frequency range to be analysed as you like.

In the EMF (LF) spectrum shown here, a frequency range of approx. 20Hz to 60Hz from left to right is being analysed. During analysis, the Auto Marker feature has determined - fully automatic - two main signal sources:
Signal#1=30Hz at 45µT
Signal#2=50 (mains power) at 75µT

The very common low cost BROADBAND MEASUREMENT DEVICES (especially common among novice users) do not give you too valuable information at all. You do receive a measurement result (for example, 500nT), but what is the frequency ? Of how many radiation sources is this result composed? What causes the radiation ? Are there multiple sources ? Is the reading maybe even composed of several signal sources ? What is the corresponding exposure limit for this reading ? What IS the exposure limit if a mixture of several frequencies is present ? Questions and yet more questions WITHOUT an answer. In contrast, using a SPECTRUM ANALYSER, you will ALSO consider the frequency of the signal sources, as the frequency is JUST as important as the signal strength itself. ONLY using the frequency information, a radiation source can be isolated reliably, and ONLY using the frequency, calculation of frequency-dependant exposure limits can be accomplished.
Due to the MISSING frequency reference with low cost broadband units, DRAMATIC misinterpretations can arise: when exposure limits are calculated, these can be wrong by MORE than a factor of 1000!! (this is NOT an error, we do really mean ONE THOUSAND).

LONG-TERM MEASUREMENT (Data logging feature)
For SERIOUS measurements:
SPECTRAN® measurement devices with data logger allow long-term recordings of measurement results over a freely adjustable period of time. This is particularly indispensable for SERIOUS evaluation of exposure by appliances and machinery which have a changing power consumption or radiation strength over time. Examples for these include railroads, power lines and plants, but also home appliances and their respective power cables, and various high-frequency transmission facilities like mobile phone transmission towers, mobile phones, radar etc. Depending on the time of day, CONSIDERABLE variation of exposure can occur (see attached graphics). WITHOUT long-term recordings, MASSIVE misinterpretation of total exposure can occur. With long-term data logging using SPECTRAN®, the daily variation of exposure can be recorded and analysed. Thus, the ACTUAL total exposure can be evaluated precisely.
With this functionality, you can even discover sporadic EMC problems which would otherwise be very hard to detect.
Even though SPECTRAN® units "only" last 4 or 7 (depending on model) hours with one battery charge, the intelligent "Powerdown mode" enables much longer data logging and measurement timespans. Finally, if this is not enough, the external power supply can be used to extend the recording timespan infinitely.

Long-term recording with SPECTRAN® units is particularly INDISPENSIBLE with measurements of appliances and their cabling if their power output or radiation varies considerably with time. The attached screenshots show the EXTREME variations which can occur in the course of a day. This is a fact widely unknown by many users. In the worst case, measured at the "wrong" time of day, very low levels could be measured, even though the exposure, not to talk about peak exposure, might be higher by a factor of ONE HUNDRED THOUSAND (this is NOT an error) at a different time of day. Great caution needs to be taken, especially if measurement is performed as a commercial service: The very common practice of short-term measurements (being more cost-effective) often cannot evaluate the ACTUAL daily level of exposure.

At the push of a button:
Exposure limit calculation used to be a complex and awkward procedure even for the professional, as most of the time, a chaotic mixture of an abundance of different frequencies, modulations and signal strengths is present.
The indispensible, highly complex calculation of frequency-dependant exposure limits can ONLY be performed CONFORMING TO STANDARDS by a spectrum analyser with high-performance software. Not a problem for SPECTRAN® units: They can calculate even several authoritative exposure limits, precautionary limits and recommendations (simply selectable via a button) and display these as a practical bargraph display (including convergence display in percent!), while the measurement is running.
The attached SPECTRAN® screenshot demonstrates how it works: At the push of a button, the ICNIRP exposure limit has been chosen among the various available exposure limits. SPECTRAN® now automatically calculates convergence or excess of this limit. For achieving this, often thousands of complex calculations have to be performed per second, and a steady scan of the entire frequency range needs to be performed. A true nightmare for every processor. In our test case, the graphic display shows an approximation towards the ICNIRP limit by 6,06%. If you use a NF-5030 you can even cover the total ICNIRP-banwidth (depending on frequency). Hence, even the novice can perform exposure limit calculations ACCORDING TO STANDARDS without having to use complex tables and calculators.

The very common low cost BROADBAND MEASUREMENT DEVICES (especially common among novice users) do not give you too valuable information at all. Due to the MISSING frequency reference with low cost broadband units, DRAMATIC misinterpretations can arise: when exposure limits are calculated, these can be wrong by MORE than a factor of 1000!! (this is NOT an error, we do really mean ONE THOUSAND).

The new standard: 3D MEASUREMENT
3D magnetic field measurement:
Mismeasurement caused by wrongly adjusting the measurement device in space or troublesome and complex 3D calculations with a calculator are a problem of the past from now on, thanks to SPECTRAN® EMF (LF) measurement devices. All SPECTRAN® EMF measurement devices can measure magnetic fields directly in 3D! Starting with the SPECTRAN® NF-1010E, field strengths of the individual X, Y and Z axes can even be shown seperately. This has become possible thanks to the newest development from the Aaronia laboratories: Our high-tech REAL 3D miniature sensor coil. Consisting of a specially crafted nylon base with 3 independant windings made of ultra-thin, 0,05 mm! wire, it impresses with its extremely high sensitivity. It allows measurement of magnetic fields in all 3 spacial dimensions. The signal processor (DSP) of the SPECTRAN® performs the resulting highly complex calculations. You receive 3D measurement results which can otherwise only be achieved by using highly professional equipment.

Units commonly found on the market which are particularly in use by novices for "EMF measurement" can, for the most part, ONLY measure magnetic fields in ONE dimension. Hence, by misaligning the measurement device in space, SERIOUS mismeasurement can occur: in extreme cases, no magnetic field might be shown at all even though an extremely high exposure is present. Tedious and complex 3D measurements are often not performed at all, or wrongly (especially by the novice). In contrast, SPECTRAN® can performs magnetic field measurements in 3D and thus offers PROFESSIONAL measurement right from the start!

Lots of power: The rechargable Aaronia NiMH battery
Superlong operating time:
Starting with the SPECTRAN® NF-1010E or SPECTRAN® HF-2025E, respectively, the rechargable Aaronia NiMH high-performance battery is supplied as standard. It has been developed specifically for the SPECTRAN® devices and is optimally suited for their requirements. Thanks to NiMH technology, the dreaded "Memory effect" is now a thing of the past, as with this power battery, maximum quality and long life have been our primary goals. Another reason why such a battery technology is necessary is the high power demand of the high-performance DSP used in all SPECTRAN® units, especially in the RF versions, which furthermore include very demanding RF receiving circuitry. Still, it is astounding that even when using the standard version of the Aaronia battery (1300mAh), continuous operation of the SPECTRAN® for approx. 4 hours is possible. The special version with 2200mAh (available at an extra charge) bumps this up to a stunning 7 hours! This is certainly a new all-time record for portable, battery-supplied spectrum analysers, or do you know a portable spectrum analyser which even remotely provides 7 hours of continuous operation with a single battery charge ?
Naturally, the necessary battery charger is also included. At the same time, it can be used for operating the SPECTRAN® units with mains power. The battery charger is integrated into all SPECTRAN® units, thus SPECTRAN® model NF-1010 can also subsequently be extended with an Aaronia battery (STRONGLY recommended!).
