Best Pinpoint Salinity checker?

[ForTheLoveOfCoral21]

Seeing mixed reviews about each one online, wanted to come to my trusty R2R home and see what everyone is using/suggesting.

There is only 1 pinpoint salinity checker, unless they recently changed models.

Are you asking which salinity checking method/brand overall is best?

I could be using the wrong term.

When i google this, a few brands of "pens" come up, the ones you can quickly dip into the water and it will read the salinity digitally.

+1 for the Hanna Salinity Checker

Against the Milwaukee at the store I work at, my Hanna reads 3 low. milwa 1.026 Hanna 1.023. Now that I know, I know how to mix my salt.

All the reviews i am seeing on the Hanna, say they read 2-3 low. So that's why i asked. Thank you!

My hanna is spot on compared to my refractometers.

UPDATE the statement above is not true after more testing. I now have two Hanna testers and both read 0.002 low when calibrated with Hannas calibration fluid.

I've used the actual Pinpoint brand salinity checker and it's fine. It's only drawback i saw relative to the lab instrument I used was slower to respond when first dropped into the water, presumably because it takes longer to equilibrate the temperature.

I use and like an old Orion 128 meter or something like it with a 4 electrode probe. Some reefers find them on ebay,

A number of folks complain about the Hanna. I do not know if that means it is worse than other similarly priced probes, since it may also be due to unrealistic expectations for a cheap meter.

I have and like Hana. It dose have to be calibrated now and then.

I am planning on getting the pinpoint. It’s that a monitor that you constantly leave the probe in the sump and display the reading? Or you have to manually click a button. How often do you have to calibrate it? Thx

I use the Hanna salinity checker and calibrate it once a month. Works great!

I do not like leaving any conductivity probe in the water 24/7, but you can do it.

I didn't leave mine in the water, and the calibration did not drift between uses.

I do not think it has a time out. It reads conductivity until either the battery runs out, or if you bought the AC adapter, until the power goes out.

Great. Thx
