I have been asked why I'm selling it.
The technology is really cool but I have 2 tanks to test and Mastertronic can test one of them automatically. I still need to do manual testing on the other tank which kind of defeats my original plan of not having to worry about testing.
I have all the Hanna checkers, adjustable pipettes, and vortex mixer so once I sit to start testing one tank, doing a second one doesn't take much longer.
Mastertronic is doing all the tests twice a week for me but I'm starting to dose individual elements which require more frequent ICP tests so between ICPs every other month and weekly manual tests I think I'm covered.
