I'm in the middle of a minor meter crisis, which is better than a minor midlife crisis!
So I dug my old TDS/EC meter out and wondered how the heck and what EC calibration solution to use. I have some, wrong stregnth(?). Start googling and this video came up. According to it, you can mix 0.7459 of potassium chloride into 1 liter of distilled water for an ec of 1413 micro somethings....
Can someone confirm or debunk that. If it's true, then is there a chart somewhere with the amounts of potassium chloride to add for other ec calibration settings?
Enjoy the video!
