The series DIP 40- offers a complete range of highly accurate program-
mable digital panel meters. Each instrument is equipped on front face
with a five 14mm high red digits display whose brightness suits applica-
tions in industrial control rooms perfectly.
They allow the display, the checking and transmission of data from any
measurable magnitudes.
