Keeping that in mind but now a new question. How often do you have to calibrate it? How many uses before you have to?I purchased that Hannah checker and it’s highly inaccurate. A lot of members agree with me on this.
I listened to a member on here and got the Milwaukee and I’m so glad I did! The hannah checker is getting returned.

yeah, I had the same experience.... moved to the Milwaukee and have not looked back!I purchased that Hannah checker and it’s highly inaccurate. A lot of members agree with me on this.

Cheap and good is a basic refractometer. Only downsides to it is that you need overhead lighting and squinting of the eye. Occasional salinity testing is not a problem, and I’ve personally used a basic refractometer and it got the job done accurately.What are some good, cheap salinity testers?
are there any devices where its just simple? Salinity pens, digital salinity? I just don't want to deal with a refractometerCheap and good is a basic refractometer.

I graduated to a higher end because I have over 7 tanks in my house (99% are temporary QT’s, and it was too much effort for me.
The hannah tester was inaccurate straight from the box. Even with prior calibration! Note: the tester from Amazon arrived to me used and a lot of reviews mentioned the same thing which is infuriating when you are supposed to receive a brand new unit.
Here’s the deal: there’s no perfect solution.are there any devices where its just simple? Salinity pens, digital salinity? I just don't want to deal with a refractometer
not against it but id rather not have to go in my tank, use my pipette, calibrate it, wait 20 seconds and check. I was looking for something thats just dip and you get resultsI have the Hanna, Milwaukee, and a 20 year old optical refractometer. If cheap and reliable are what you're looking for honestly the optical refractometer is a great choice, just curious why so set against them? My Hanna reads about .002 too low so I just add that to whatever my reading is. Hanna is the easier digital one to use IMO but neither of them are what I'd consider hard to use. I also really like the Milwaukee digital refractometer, but I don't trust either of the digital ones compared to a properly calibrated optical refractometer.
I haven't calibrated my optical refractometer in years, simply because I haven't needed to. I do check it against a known solution periodically though. Any salinity tester will take a small amount of work and the optical refractometer isn't any more than most of them IMO. The closest one to what you want I'd agree is probably the Hanna that you were originally asking about. For it I just dip it into the tank, then dip it into a cup of rodi water to rinse the probe, shake it off and I'm done. I've not had the best accuracy with it, but it seems to consistently read low, so it's not too big of a deal. If I'm in a hurry I use the Hanna, and if I want to make sure my reading is right I use my digital and/or optical refractometer. Plus for my tank I can verify my results against my apex (or at least try to , sometimes it's salinity probe is absolutely awful).not against it but id rather not have to go in my tank, use my pipette, calibrate it, wait 20 seconds and check.

Does it matter what kind? I think I may have one lying around here somewhereI haven't calibrated my optical refractometer in years, simply because I haven't needed to.
