I buy few of these product and believe that it is foodgraded because desription says:
“This one is suitable to detect flow in water dispenser or coffee machine.”
But when someone was asking “food Safe” question, the answer was “No,it isn’t “food safe””
How that is possible?
I’m not sure who said the sensor wasn’t food safe. From my reading of the FAQ, the forum, the wiki, and the manufacturer’s page, it all appears to be food safe.
As always, though, it is good to check the laws relating to this in your area. Different countries and geographies have different safety standards.
Best wishes!
