Selective Level Meters

Accuray measure signal levels with a preset bandwidth on two frequencies simultaneously

N4L have been developing and manufacturing Selective Level Meters for many years, the SLM2200 was the original model released and significant development has taken place over the years. The latest Selective Level Meter model is the SL3505, this instrument is extremely versatile, features and integrated signal generator and offers true portability as a result of its internal rechargeable battery pack. The SLM3505 has a full colour TFT display and USB memory port for data storage.
