This should not be marketed or recommended to reefers. I bought mine partly based on this video, it measures off by 3 ppm, when contacting my local hanna, they said its not suitable for reef aquarium testing as it tests nacl (im not a chemist). After some discussion they agreed to take the unit back though.
Just got the Milwaukee didn't like it. But good to know about how to care the optical and not scratch it. I hope I can get this thing to work properly but so far the digital hanna pen (conductivity) works way better for me and way more precise.

These are great meters to measure salinity, I love mine. I didn’t know about covering it with you hand, good tip, thanks
