I need help with measuring PO4

[Delphinus]

Incidentally I did a test on my RO/DI water and it came out as 0.01.

But I guess now that I've established that I can't express any confidence in the test results, it doesn't really matter. I might as well say that my RO/DI tested as elephant, it makes about as much sense.

Did you try asking the poeple at the city water treament plant or the waste treatment plants. For sure those guys test for phosphate

I talked to a chemical lab about doing a water analysis. It's a bit pricey but you get a whole panel done.

Hard to say. Seems I can spend $100 to get a water analysis, or $100 to buy a Deltec/D-D PO4 test kit, or spend $100 to buy some reference samples.

Ouch.

Anyhow. BUMP. Is there nobody out there who can help me test some PO4? Come on, someone has to have a test kit they believe in ... please ? It's going to be a long hard road fighting with Hanna Instruments and I need to know where I stand before I embark on trying to get them to repair this thing if that's what's called for.

Someone? Anybody? Bueller? Bueller?
