only just seen this thread i am sorry to say i havent logged on for a while so a bit out of touch.
I was wondering has the art of reading a lamp gone now there are electronic devices, a good garforth in the right hands will give accurate reading of gasses. ok there could be folk that say a lamp is out of date but after years of relying on one I would put my trust in a flame before I would a microchip.
Interesting to see what others think, or am I just too old :bored:
