AMTAST Salinity Refractometer Salt Water Tester ATC Automatic Temperature Compensation for Brine, Food, Industry, Seawater 0~28% Scale Range, Made of Copper Not Cheap Aluminum

Do not buy this if you want it for a saltwater tankIt does not measure 0.0- salinity

not for a marine tank as it gave % of salt not a recognised measured

I just switched to a saltwater pool, and needed this to keep an eye on my salinity.It works great!I don't have anything to compare it to, and it's a bit tricky to use properly, but if you follow the instructions it's not bad at all.

We learned about the issues of having too much water vs antifreeze last time we had a hard freeze in our area. Wife's Uncle added too much water to the radiator of one of our Suburbans, instead of antifreeze. End result was a hard freeze atypical to our region of the country, and we weren't able to drive it until we heated the radiator. After that, we absolutely needed to know how much antifreeze versus water there was in our different vehicles (especially those that my uncle-in-law would use or maintain). This gadget works great at providing accurate results, quick.

Die Gesamtkonstruktion ist sehr gut. Für meine Anwendungsfälle ( Salzwasserpool ) hätte ich mir, unterhalb der 1% Markierung, eine feinere Einteilung gewünscht.

Macht was es soll nach kalibrierung zeigt es sicher den Salzgehalt meines Teichwassers an. Für den Preis Top..
