- Neptune Systems Conductivity Calibration Solution - 53000 Microsiemens
53000 µS Conductivity Calibration Solution - Use this calibration solution to calibrate your Conductivity Probe and PM2 for saltwater salinity monitoring applications.
Conductivity probes can be used for many different functions from letting you know the salinity of a tank to the quality of RODI water. We suggest calibrating conductivity probes once every 3-6 months to keep readings reliable.
447 µS Conductivity Solution - Used for calibrating conductivity probe for freshwater applications.
53000 µS Conductivity Solution - Used for calibrating conductivity probe for saltwater applications.
This is the actual Neptune solution packet By Drew on 7/23/2018Drew would recommend this product to a friendI was a little hesitant to purchase after looking at the picture, for fear of an off brand product(even though it says same type of solution). I was pleasantly surprised when I opened my order and found the same solution that came from the factory with my apex unit. The key for me was floating he bag in my sump for 20 min so the solution got up to temp before calibrating. Yes, it’s true that the reading is slightly off when compared to a refractometer, but I realize that is a different instrument. I bought that fancy ice cap salinity pen and it reads something different too. So for people like me, that are looking to check in on their work tank from home, the calibration fluid got my probe close enough to what I believe is the exact reading of my tank, and let’s me know that my tank is stable when I want to check on it.
It probably works By John on 4/9/2018John would recommend this product to a friendTo be honest I tried three packets and couldn’t get my apex to calibrate on automatic or manual calibration. Realistically this is a reagent so I am sure it is what it is supposed to be but that probe is finicky
Worked as expected. By MTWiley on 10/27/2016MTWiley would recommend this product to a friendThe solution worked fine for calibrating my conductivity probe. Some people have complained that it doesn't read the same as their refractometer, but you're measuring two different things. The refractometer as the name implies is looking at the refractive index of the water and using that to give you a reading. While the conductivity probe as it's name would imply looks at how conductive the water is and gives you a reading based on that.
While we can extrapolate/infer salinity from both of those readings, they're two fundamentally different readings and will always be slightly different.
It's also important to keep in mind that whether or not you are using temperature compensation will make a difference in accuracy for both and generally handheld refractometers don't take temperature into consideration, the Milwaukee Digital Refractometer is an exception to that though(not really a handheld refractometer).
Didn't work out for me. By DG on 10/18/2016DG wouldn't recommend this product to a friendI used the 1 pack that came with the new apex. Couldn't get it to calibrate. It read 32.
Purchased a new packet. Still couldn't get a reliable reading after calibrating.
Thrid time I forgo the calibration fluid. I really like they Milwaukee electronic refractometer and trust it. So I got my tank water exactly where I wanted it using the Milwaukee then calibrated the probe to my tank itself. Now it reads what I expect it to read. I likely will not try calibration fluids again. Just calibrate to match my Milwaukee.
Mis labeled? By David on 4/16/2016David wouldn't recommend this product to a friendI bought one of these for setting up my conductivity probe, just for giggles after calibrating my probe I ran a few drops on my Milwaukee digital refractometer, ran consistently at 1.018SG. I thought my refractrometer was off so I checked it against my tank 1.026, RO 1.000, and the calibration soluton 1.025). opened a second one from the same lot and same readings.... no wonder why my probe given bad readings.
stick with the Milwaukee, much better investment.
It does what it is for. By Chavinpat on 2/13/2015Chavinpat would recommend this product to a friendI used other brands Conductivity Calibration Solution to calibrate my Neptune Apex Conductivity Probe. The probe did not calibrated correctly (many trails). The reading would be higher (60 ppt) then what it actually was (35 ppt). I decided to order Neptune Systems Conductivity Calibration Solution. My conductivity probe is now back online.
Get Multiple with your New Controller By Michael M on 11/22/2014Michael M would recommend this product to a friendYou will want to double check, and if you should happen to misunderstand and miss the fact that you need to calibrate in AIR first, you could contaminate this while reprocessing, and wish you had another. You can make your own if you have the right equipment and experiment, and I do, but I want lab-grade references at some point.
You will want more than one with your new system.
Don't pinch pennies now.
