The best on the market
Don’t be fooled by the Chinese pens on the market. This is fantastic. Well worth the extra money. The calibration function is bang on

Best way to measure salinity
I upgraded from the old school hand held Refractometer. Works exactly as advertised. No fuss. Really easy.

Works great

Super easy and accurate
I also have the icecap digital tester, I haven’t been happy with it at all. Not accurate and with no calibration it’s basically useless. I preordered the Poseidon Salinity Pen and wow was it worth the risk. This thing is super accurate all the time. And it’s soooo easy to calibrate. A must have for every Reefer.
