Low Frequency

This is the device for technical amateurs - especially easy to operate. It allows a straight forward assessment of the exposure, a determination of suitable remedial actions, as well as a control of their effectiveness.

Frequency: 16 Hz - 2 KHz (compensated, better than -2 dB)

• Low-frequency electrical & magnetic fields (LF) from 16 Hz to 3 kHz
• New: 3D-measuring of electric and magnetic fields (otherwise only available in very expensive devices)

• Frequency range: 16 Hz - 100 kHz
• Electric field strength 1 - 1999 V/m
• Magnetic flux density 1 - 1999 nT
• Measurement accuracy: +/- 2 % deviation
• Application examples: Traction current, power lines, induction stoves, power supplies, consumer electronics

This device supports all above mentioned "common advantages". It is especially popular among medics and alternative practitioners, as it offers a perfect combination of easy handling and professional measurement possibilities. 

Frequenzbereich: 5 Hz - 100 KHz (compensated, better than -2 dB).

This device represents the low-cost access to the professional low-frequency measurement technology. Its functions and features are tailored to the needs and practical experiences of the building biology.

5 Hz - 100 KHz. Switchable, internal frequeny filter: 16.6 Hz bandpass, 50 Hz highpass, 2 kHz highpass for identification and evaluation of sources of pollution.

Tenmars TM-192D (with USB datalogger) 3-Achsen-EMF Meter for electro magnetic fields

• measuring electromagnetic fields
• Frequency response: 30Hz to 2000Hz
• with USB datalogger

The NFA30M is the lowest priced meter of this series, but also a "real NFA" allowing a three-dimensional magnetic field measurement.

Frequenzbereich: 16 Hz to 32 KHz (compensated)
