- The NFA400 also comprises all unique features of the NFA series.
- Frequency range: 5 Hz to 400 kHz (compensated)
- Comprises the complete range of the TCO-guideline for computer work enviroments
- ONE-dimensional potential-free measurement of the electric field (Y-axis).
- Non-isolated electric field measurement possible with integrated sensor or with the optionally available TCO conform probe TCO3.
- An integrated voice recorder facilitates the measruement analysis.
- Please have a look at the data sheet (to be found under "available downloads") for detailed descriptions of the broad performance range of this meter, also in comparison to the other NFAs.
- Please find the most current version of the firmware under "Downloads" at the top right of this site.
