Loos makes the best known gauges for both wire and rod rigging. Available

I was going to post some links, but realized that the OP is not in the U.S. and
would get more useful links by doing his own search where he is located. This
link will at least let him see what it is he's looking for! Thanks for the
addition.

Thank you very much. I have also found few Loos retailers on this side
of the Ocean. Unfortunately I will need both rod and wire gauges and for
a couple of ranges which makes the total purchase rather expensive. The
idea is quite simple so I wonder if it would be very difficult to
construct a device myself; calibration would be an almost impossible
issue but, at least, once the tension of the rig is nearly set at a
correct value by an experienced rigger, a selfmade device could be
helpful in equalling the tensions at both side of the mast and
maintaining it in time.

The mechanical device is for sure the easiest way but... any idea why a
"twang hearing device" would not work? Maybe a piezo pick-up and an
oscilloscope? In any string instrument the change of the pitch is
strictly correlated to the tension (beside the mass/length, the
stiffness coeff., etc etc of course), isn't it?
