inch conduit when it is standing like that ?
Quick electrical colour coding question?
Is the PVC conduit you are using coloured orange to indicate for
underground use & no UV protection ? it usually has a thicker wall size &
smaller ID than the Grey light duty UV proof conduit. I've noticed a
difference in properties between the 2 types of conduit when I have
magnetic fields around polymer's during my experiment's.
Also if you are using a digital camera ,(single chip CCD non SLR ) to take
photo's you are best to light the area you want to shoot under light from a
UV pair of 36/7 watt fluro tubes with a good reflector behind them. I've
been happy using most UV fluro's tubes for digital photography in general ,
barring the nasty germicidal types & the "blue black" disco style UV's
from the 1970's.
Candle light is at the wrong end of the spectrum if you want a photodiode
to take a good picture quickly :)
