So we found an old Lovinond Tintometer at work today. It's old, has a serial number of 1089. Tried to find info online and all I found was a link to a model in the national museum of natural history and that one has a newer serial than the one we found, made in 1913. Anyone know how to use one of these.
You should have a square glass receptacle(s) to put your fluid to be measured inside, that slips in the viewer on one side, the glass plates of different lovibond slip in the other side for side by side comparison, etc. You can see the square receptacles in the picture here: http://www.worthpoint.com/worthopedi...t-lovibond-eye
Newer, better, more streamlined sig as per the forum police.
