Mega Electronics 600-003 SN110 Seno Normal Developer Applicator

Excellent developer, its much more reliable than sodium hydroxide and saves time as you dont need to carefully mix it & make sure its at the right temperature. Its supposedly safer than sodium hydroxide as well. Its easy to over (or under) develop with sodium hydroxide as its very picky about concentration and temperature. However, the Seno developer comes pre-mixed at the correct strength and in my experience doesnt seem to be affected too much by temperature. Since switching over to the Seno 110 developer (about a month and a half ago) I havent had any problems using it. The Seno developer also lasts much longer than I was expecting as less of it is needed and little of it is wasted thanks to the applicator design.
