Water resistance has been discussed from time to time and I
thought it was about time getting some numbers on the subject.
So here's a couple of unscientific yet controlled measurements
on tap water as well as "sea" water 35g/l (made from tap water
and table salt). The probes used: Tilted to better show the
setup All measurements was made with the probes vertical. As can
be seen, the probes are held apart with a piece of plastic cut
from packaging material, folded and punched with 2 holes each
going through two layers (to get the probes parallel) Distance
between holes/probes was made 10mm ("air" between the tubes). To
sum up... Material: Brass tube Diameter: 5mm outside, 4mm inside
(to fit banana plugs) For the measurements, the probe pair was
submerged 61mm, and thus had a submerged area of 958.2mm^2
(9.582 square centimeters or roughly 1.5 square inches)
each.Water resistance measuredTap water (rather hard water):
18k5 after about 3..5 minutes.Salt water (35g/l of same hard tap
water): 3k0 after about 3..5
