Your right not much to it. As for the PPM you don't know if its too high or too low. Do you know if its a no-rinse type? I'd want to know this first before using it with my beer.
I'd call the company, odds are they might not know these particular details unless they sell to wineries or breweries.
Sanitizer is cheap. If I were you I would not try to pinch a few pennies until I knew how to use in properly. Start with idophor, starsan or one-step.
FYI - Idophor is supposed to be used in 12-25ppm range according the state of Wisconsin.
I'd be concerned about off flavors if the concentration is 200ppm, especially if you don't rinse.
BTW - I'm a mechanical engineer that does a lot chemical work. I have several colleages who are Chem-E's. I can ask them if nobody else chimes in for you. They are also Homebrewers...
