Saw this over on DW and thought it has potential and a good concept for solutions where products can be used at different dilutions (APC for example). Just need to see how and if we can buy them. http://www.cyndan.com.au/products/dual-liquid-trigger-sprayer-chemical-spray-equipment-1.aspx
Folks this has been around since the 1992. It was invented by Rudy R. Proctor of Anaheim, CA, patent no. 5152461 You can find in the States here and elsewhere: Dual Chamber Sprayer I own one and it actually works quite well. Mine has the control dial, the link above does not. Here's a link for both models in the U.S.: Dual-Liquid Sprayer
Thanks for the links, I may pick one up...had not had a chance to do a search for them but was going to tonight. Think it is worth the price? How far do the dilutions go to the high and low end?
I've had mine for well over a decade so I don't even recall what I paid for it. The control dial model has a numerical value of 0 - 5; 0 is water (or what you have in the bottle) only, 5 is full strength of what product you are using and the 1 - 4 being a ratio of the two.
