Selective nanovoltmeter Unipan 233 (Unipan-233, Unipan233)
Designed for the selective measurement of very small values of AC voltages in the range of 1.5 Hz - 150 kHz
The limits of the measured voltages:
The selectivity of an octave (steps) 0-18-36-54 dB.

Selective nanovoltmeter Unipan 233 is designed for the selective measurement of very small values of AC voltages in the range of 1.5 Hz - 150 kHz, nanovoltmeter Unipan 233 may be used:

- To measure small AC voltage in the presence of background noise or strong interference,
- For the spectral analysis of harmonic and noise processes at the level below the main component,
- A highly sensitive indicator of the balance of various AC bridge circuits,
- As a measuring amplifier with a bandwidth of 0.5 Hz - 400 kHz (-3 dB error)
- For photometric and spectrophotometric measurements using the acc. transducers
- For research in the field of solid state physics, nuclear engineering, physical chemistry, and other areas where you want to measure very small values ​​of physical quantities that can be converted into electrical signals,
- As broadband microvoltmeter ranging from 1.5 Hz to 150 kHz.
