Recent Trident NP experiences?

[Ioncewaslegend]

I've heard mixed reviews from he Trident NP on launch, with some people saying it's gotten better over time.

Curious how people's experiences have been lately after the updates.

curious as well -- following along

Funny I was just thinking about making this thread earlier this week.

From what I’m still hearing after returning mine that they are junk. Results are accurate for about 7-10 days after reagent change and then they taper off. Thoughts are the reagents settle out. Could possibly be fixed by using a stirring bar in the bottles to keep them suspended. It’s likely only the solution for phosphate which needs stirred. I can’t remember which one that is.

Neither is needed. Not sure where this is coming from.

Neptune has released a couple NP firmware updates along with their Apex OS. They have also added in the much requested manual calibration feature.

If you are in no rush you can always wait a bit more as the manual testing using Hanna checkers for Nitrate and Phosphate can be done in under 10 minutes if that. Pretty painless.

Neither is needed? How so? I know atleast 10 people with them. Not a single one has successfully had a month of tests.

Maven is using a stirrer for some reagent as it settles out. They use the same testing standard as far as we can tell.

You ought to do some research before commenting.

Well if you have a reference handy for the NP requiring a magnetic stir I will stand corrected. Same applies for the testing standard they are using being the same as the Maven. But believe what you want to believe.

You really are clueless. And that’s ok. Keep at it.

There is nothing to keep at my fellow hobbyist. You either have factual information or it is an opinion. I'm cool either way just call it out next time. I am aware of your initial NP trials and tribulations and did not discount that.

Hope your evening is well.

I'd imagine the idea is that:

There's relatively limited ways of testing the same analyte

These ways are further limited by being suitable for hobbyists (relatively non toxic, able to be stored for a certain period of time at ambient temperature, etc)

This increases the likelihood of the NP and the Maven using the same set of reagents, which means

The Trident reagents likely have stuff precipitate out of solution as well, which would be consistent with accurate initial tests followed by slowly decreasing accuracy

I'm likely giving up on the Maven and going for an NP. If I do I'll likely jerry right a stir plate hooked up to an automated timer on each reagent and see if it stays consistent.

Nailed it.

My nitrate test was accurate. My phosphate was not. No matter what I did. Give it a shot on phosphate regents and see what happens.

Sounds like the opposite of my MT. I spend 3 months on like 12 multiple hour help sessions with both my Alkatronic (which is now dead and Eric won’t replace it) and my MT. I’ll limit my comments to my MT. When the tech (great guy, but want to keep his name out of this) he shared with me that the only reagent that remotely works for No3 is the API kit. And, you have to spend about 15 Minutes shaking the bottle to suspend, if I recall correctly metal like flakes, that are in the reagent. You. An actually see the sediment of these flakes in the bottom. As the bottom becomes “clean” you have suspended this material. Once you put the API in, it mixes every 12 hours to keep these flakes suspended. With the MT my Po4 is almost identical to every Po4 Hanna test I do. But the No3 has never, not once, EVER even come close to an ICP or my Hanna. It’s usually less than half the value of my ICP. Focustronic gear is some of the worst purchases I have ever made. This includes my Mana crypto. f U Zuckerberg :)
