Refractometre/PinPoint Salanity monitor/Milwalkee Conductivi
 

I am having a hard time deciding with of the 3 products to invest in. I want high accuracy, low maintainance, easy to use, and bang the buck!
Of the 3, which is least needed to be calibrated on a regular basis? Please, anyone with personal experience, give me your opinion. Thx.

Will

by the way:
Bue refractometre - $42
Pinpoint Salanity monitor - $115
Milwalkee conductivity - $70

Um Your in the wrong hobby :biggrin:


None of them are really necessary, unless your a gear junky then half the fun is calibrating them.

If you have a CA reactor I would say get the pinpoint PH Monitor. Even if you don't I think its the most important. But it also requires the most maintenance.
A refractometer is cool but not as important. I would say it's the least for maintenance as you can calibrate it with RO/DI water.

The best bang for the buck would be the swing arm salinity hydrometer. Next would be the refractometer. I don't have any of those 3 devices at the moment although I might get a refractometer 1 day.

Are you kidding me, " it's not necessary"? You're in the wrong hobby my friend.

I do run a CA reactor, but my concerns are with the Salanity testing/monitoring equipments, not Ph.

thanks anyways.

Hey Willito

Where can you get a refracrometre for $42?

Thanks,

Trevor

Ps - I have a Pinpoint Salanity meter and it started acting up on me. Currently I'm not a big fan of the thing considering it wasn't that old.

I think those are US dollars.

I didn't mean to offend. I guess I'll stick to the fact and not attempt any humor.

What I meant by not needing any of the products is that alternatives that are less expensive and require no maintenance are out there. Swing arm salinity hydrometer, PH test kits. In my experience ( PH monitor, refractometer) they need a great deal of calibration and must be kept clean. Plus when there is a reading that is not normal the first corrective action is to clean and calibrate the unit. PH meter (Pinpoint) with the AC adapter are really susceptible to electronic noise and can give erroneous errors when calibrated perfectly.

Thank you for your opinion, that makes much more sense.

With that info I am leaning more towards the refractometer. I didn't realized what the drawbacks were with the electronic monitoring equipments. Now that's something to think about, convenient vs. accuracy. Too bad they don't go hand in hand.

I've heard with the pinpoint if you just use a 9V battery you eliminate the noise factor. It is a great devise, just touchy
