Product information Fixing Bath Tester
The residual Hypo Tester is used to test the washing process of prints.
For example, you would run a test page through the washing process, and drop a bit of the hypo on the print. If it liquid turns yellow, the process/print is not clear of Fixer and you qould re-wash the actual prints.
The residual Hypo Test is a simple chemical test that can be used to determine if a print or film strip has been adequately washed. The test is based upon the formation of a yellow stain of sylver sulfide-silver thiosulfate on the white of atest print, or the clear area of a negativefilm stripwhen the test solution is applied.
The reliability of the test depends upon the washing procedure.
The chemicals in this kit are mixed and ready to use with NO further dilution. Shake well prior to each use.
