Frekvenstællere

Nortelco Electronics tilbyder håndholdte og stationære frekvenstællere fra Tektronix, TTi og Pendulum. Frekvenstællere benyttes til at måle frekvens. Frekvens er defineret som en række begivenheder af en bestemt art der optræder i en given periode.

Nortelco Electronics tilbyder følgende frekvænstællere:
