An unused (indivisible) set of 3 hydrometers for testing the E-6 1st Developer, Bleach Bath and the Colour Developer.
Bought when KODAK removed it from the catalogue.
These were used to check the density of the usage solutions. The density evolved, during processing, by the transfer of the previous (rinse) baths and also the possible chemical contamination, the detection of (rare) starter/mixing errors and also in the pH corrections of the Colour Developer.
This was/is a mandatory test to meet the standards of the KODAK Q-LAB system.
Each Hydrometer is adapted for the specific bath, hence 3 pieces, but can also be used for other processes including B&W Reversal and C-41.
This was my spare set and has therefore never been used and it is in new condition, the plastics are still perfectly elastic.
For sale in Continental EU and Eurozone only (delicate glass and taxes).
Price: € 150.- + shipping.
