Manual home testing vs ICP

[Biff0rz]

I've been sending out some ICP's and thought it'd be worth doing some manual tests at the same time to compare the accuracy. There's a lot that goes into the accuracy of both testing measures but I am at least consistent w my manual tests and try to do things as accurate as possible. These are the results of my most latest (5/8 sample, 5/19 results) ICP/manuals at the same time, but all prior tests are pretty much the same which speaks to my personal methods in manual testing (or so I like to think lol)

Here's what I found-

Param	Manual Result	ICP Result	Manual Brand/Type
NO3	25.2	28.33	Hanna / Oceamo-MS
PO4	0.17	0.124	Hanna / Oceamo-MS
Alk #1	8.23	8.22	Hanna / Oceamo-MS
Alk #2	8.40	8.22	Alkatronic / Oceamo-MS
Alk #3	8.42	8.22	Trident / Oceamo-MS
Ca #1	450	409	API tritration / Oceamo-MS
Ca #2	421	409	Trident / Oceamo-MS
Sg #1	1.0261 / 34.64	34.4	Tropic Marin Hydrometer / Oceamo-MS
Sg #2	32.1	34.4	Hanna Tester / Oceamo-MS

I'm pretty happy with everything overall. Particularly happy with the TM Hydrometer :)

Anyways, I thought this was cool information and will continue to track it.
