A must have for salt aquariums
This arrived on time at first I thought it was broke the instructions that come with it were very basic and was about to send it back when I came across the video for it that explained it so much better. Happy fish happy owner it keeps a good reading, just don't put too much water on it. Tip to reset use ro water first that should show all blue if not set it to all blue before using saltwater otherwise you will get a false reading. Highly recommended for new reefers.

Buy it
Great for the money, accurate and stable, maybe a bit flimsy compared to my last refractometer but less than half the price.

Couldn’t be happier! Works perfect, came perfectly calibrated and even came with a dropper of distilled water to recalibrate in the future. Sturdy laboratory grade product.

Ho scelto questo modello della Sungrow perché aveva buone recensioni online e mi sembrava un buon compromesso tra prezzo e qualità. Devo dire che non mi ha deluso. Ho anche apprezzato che spesso questi rifrattometri vengono forniti con una piccola soluzione di calibrazione e un panno per pulire il prisma. Calibrarlo è un'operazione semplice, la sua funzione specifica per l'acqua dell'acquario è un grande vantaggio, perché la scala di misurazione è ottimizzata per i valori che ci interessano. Utilizzare questo rifrattometro è davvero semplice. Basta prelevare una piccola goccia d'acqua dall'acquario con la pipetta inclusa (solitamente fornita, nel mio caso c'era), depositarla sul prisma dello strumento e poi guardare attraverso l'oculare puntando verso una fonte di luce. La linea di demarcazione che si vede indica il livello di salinità. È molto facile e veloce. Io mi sono trovato benissimo e lo consiglio.

Das erste mal dass ich ein Refraktometer besitze. Die meisten kosten zwischen 20 € bis 40 €, was kann man da für nur 10 Euro erwarten? Hinweis: Hat Anfang Nov. 2022 nur 10 € gekostet. Die im unteren Preissegment scheinen alle dieselben zu sein, dem Aussehen nach. Ich musste meines nach Ankunft nicht kalibrieren, die Werte stimmten auf Anhieb. Anleitung ist auf englisch (für mich kein Problem) und befindet sich im Gehäuse unter dem Schaumstoff im Deckel - muss man erstmal finden. :-) Ich habe drei verschiedene Proben entnommen: - dest. Wasser 0‰ Salinitität = korrekt - Meerwasser 33 ‰ Salinität = korrekt, genau so wie es auf der Meer-/Riffsalz-Verpackung stand - Meerwasser 53 ‰ Salinität = korrekt, genau so wie ich es mit der Feinwaage abgewogen hatte Bisher kann ich nicht klagen, habe aber nicht auf die Dichte geachtet, da für mich die Angabe der Salinität ausreicht. Ist auch eher simple Technik, da braucht es keine 40 Euro für so ein Gerät. Es ist ein Prisma drinnen und eine automatische Temperaturkompensation (physikalisch, ganz ohne Batterien). Das kann auch jeder kleine Chinesenladen herstellen. ;-)
