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.

Frequency range: 5 Hz - 100 KHz (compensated, better than -2 dB)
Switchable, internal frequeny filter: 16.6 Hz bandpass, 50 Hz highpass, 2 kHz highpass for identification and evaluation of sources of pollution.

Features:

• Responsivity increased by a factor of 10 (minimum display resolution: 0.1 V/m / 0.1 nT).
• NiMH battery, battery charger / power supply unit included.
• An AC- and a DC-output.
• Increased reliability by the use of a test switching mode for the zero deviation.
• Perfectly suitable also for potential-free measurements with the help of the potential-free mounting for LF measurement devices.
