How are you checking salinity?

[kamike91]

I do. It’s great. Drop it in and you can monitor the results of water or salt additions in real time. Same for mixing acclimations and up limewater/kalkwasser.[emoji3]

I didn't know they had handheld ones. I'm only familiar with the apex controller and conductivity probe which I have. Could I use this in the same applications? I notice with my probe I have to let it sit for a while before I get a consistent reading.. Maybe because it's about 2 years old.

I wouldn’t trust it. Hated mine. Terribly inaccurate/inconsistent and Neptune won’t even own up.

Ok thanks

what do used Orion model 128 sell for? Interested in finding one...

I got mine for $100. Lucked out since it came with what appears to be a relatively new probe that goes for over $600 new.

I use the vee gee stx3; I check it with acurasea and the vee gee solution every once in a while, had it for years never had to calibrate. My profilux conductivity probe seems to be way off..

I was just able to snag one on eBay for $80!

congrats! what probe did it come with?

 

[smcquary]

Hopefully one for what I need! It says it is an Orion
conductivity cell 013010

They make a range of probes, but yours is the same as mine... a very good probe with a huge range of use.

Yes, that's a good one (assuming it works :D):

Thanks! Yes hopefully it works, but they do have a 30 day return policy so I should be okay. Excited to get it

Calibration solutions AND a case! Good find

It looks like there may be a manual as well.

If not, I was able to get a pdf manual from them for mine :)

I use a pinpont conductivity meter. I like it and I feel it is easier then a refractometer.

I used one for a long time in parallel with my Orion 128. The main difference I noted was a slower response time to the Pinpoint (presumably the temperature correction changing slowly as the probe changed temp to adjust to the sample), but it always worked well.

As an aside, it doesn't have the range the Orion has to do things like RO/DI, but people do not get it for that reason.

So I agree it is a good device! (in full disclosure, I'll note that American marine gave it to me for no cost, but that doesn't change my opinion of it in any way)

Old school instant ocean hydrometer, and Red Sea refractometer, no difference in readings.

Looks just like mine! It's spot on every time. Hasn't changed in 20 years ;Smuggrin
