You want a TF100 but they can't deliver to Canada, so you would need a US delivery address.
The only other real option for a test kit is a Taylor K-2006. Be careful comparing prices because the K-2006 comes in sizes, designated by a letter. The basic K-2006 has .75oz bottles. You need to get the K-2006-C to get the larger bottles that you want. Even then it is a little short on the reagent & powder for the FAS/DPD test.
I think he's asking about a Salt concentration test. I could be wrong. But that's how I read the post. If that is what OP was asking, from everything I have read here, none of them are accurate and you should do whatever makes your system happy.
