If that is the one you want to use, then it should work just fine. I use a simple light refractometer, that costs $20, for the last 5 years with no issues as well. I have thought about buying the one you are asking about, but it seems more of a luxury, than a necessity. All of them are hobby grade testers, and not 100% accurate.Is the ma887 milwaukee salinity checker worth it? Im new to the hobby. If someone can help me out.
What do you mean by this?The one thing I don’t like is the S.G. Range is only two decimal places should be three

I use them and have had decent results (some units work better than others). If you want to take a deep dive into the topic, I posted this article on the subject:

You'll need to get several and check them against each other periodically for a reference.
I have the tropic marin hydrometer and the Milwaukee digital. It's easier to use the Milwaukee so most of my readings is on that. Every now and than I check it with the TM hydrometer
I ditched my Milwaukee for the Hanna Marine Salinity Tester - it's portable, accurate, easy to calibrate and $50 less than cost of the Milwaukee - which i found to be very sensitive to water temp
Why difficult to use? Dont use just put it in water?The large glass TM hydrometer is what I found to be the most accurate, but most difficult to use. I use one to standardize my other devices.

And which milwaukee do u use? The ma877? https://www.bulkreefsupply.com/milwaukee-digital-seawater-refractometer.html is that the one? Do they have a new one of it? What about https://www.bulkreefsupply.com/milwaukee-digital-seawater-refractometer.htmlI have a cheap optical refractometer, the Hanna salinity tester, and the Milwaukee digital refractometer and if I go to check my salinity the only one I ever use is the Milwaukee.
It’s the Milwaukee MA887 that I have and is commonly used in the hobby. I don’t believe any of their other models are suitable for aquarium use.And which milwaukee do u use?

The one I have is the older one with the green case but from what I understand the color change was the only difference.
Also if you do decide to get it saltwateraquarium has it on sale for a good price.
