    R-7065 Standard CYA Solution?

    I need to order some more chems: R-0013, maybe some borate strips. But checking out the TFTestkits they also sell R-7065, R-7064, R-7063 Standard Solutions.

    Questions
    1) Are these worth having?

    2) How do you use them?

    3) What is the purpose for them?

    Thanks, John

    I think the CYA standard is good so you can confirm you are doing the test in the correct light. The others are not likely needed.

    The standards are a set level that you can test to check your reagents as well as to verify your testing methods. Since the CYA test is so subjective I recommend that one so you can train yourself what the vanishing dot should look like. The others probably aren't as useful.

    Re: R-7065 Standard CYA Solution?

    Confirming the above thoughts, our customers certainly agree. We sell FAR more of the R-7065 (CYA) than we do R-7064 (TA) or R-7063 (CH).

    Most of that has to do with the CYA test being a bit hard to interpret and having that standard solution gives you a comparison.
