Great value compared to fancier brands
I have to use refractometers at work on a daily basis. We have the red sea and the d&d versions. This one does the same job for way less cost. I do find i need to recalibrate it a bit more often, but that honestly is not a big deal, takes like 2 seconds.

Great Product but instructions could be better
When i first received this i thought it was faulty, the enclosed instructions state to calibrate screw the knob until its zeros. I tried turning knurled nob which didn’t move, so i went back to the product page and saw that it was inside this knob that needed adjusting with a screwdriver (supplied with kit, under the three pipettes) now its zeros perfectly. I feel that the 7% one star reviews are maybe due to people trying to adjust the knurled knob. Device works great if set up correctly and I’m 100% pleased with it

Works straight out the box
Just setting up 1st marine tank. So this is all new to me. The refractometer comes with a plastic case and 3 pipettes and simple instructions. I first focused it for my eyes and then checked the calibration and it was spot on. Then tested the salt level in my tank and added some more salt to bring up to the correct level. The refractometer is simple to use. Just add a drop or 2 of liquid an stand under a bright light when you take the reading. Wipe of the liquid before putting back in the case. I have no way to check the accuracy , but I feel confident it is ok.

Good reading
First you need liquid to clean then set it at 0 then do reading and it works well

Good piece of kit
Really good piece of kit, wondered wether it was worth taking a chance on a “cheap” one, but it does exactly what it says on the tin. Really simple calibration. Recommended

Wildly inaccurate
Had this tested with other marine shop to verify and was even close. Yes it was calibrated to zero . Return was made. Be careful with your reef equipment Quality it was very light . Not much more . Obviously was good enough

Ottimo strumento economico e affidabile🐠
È uno strumento che serve a misurare, monitorare il livello di salinità e di gravità specifica dell’acqua salata nell’acquario marino. È la prima volta che uso questo strumento e devo dire che fin da subito si intuisce la facilità d’utilizzo... Il rifrattometro è costruito in plastica e le rifiniture sono curate bene nei dettagli. ATTENZIONE:Lo strumento arriva già tarato, pertanto vi consiglio di non svitare la vite posta nella parte superiore(la vite è coperta da un tappo in gomma). “Per intenderci lo strumento va usato come usereste un binocolo”; Per provare la giusta taratura del rifrattometro bisogna versare con la pipetta in dotazione qualche goccia di acqua dolce osmosi nella piastra di controllo e orientare verso una fonte di luce, guardate all’interno dall’altro capo del rifrattometro. All’interno si vede una scala graduata che serve a rilevare la salinità e la gravità specifica. Se lo strumento è tarato bene noterete che la linea sarà perfettamente allineata con lo 0 nella scala graduata. CONTENUTO DELLA CONFEZIONE: - 1x rifrattometro salinità - 3x pipetta in plastica - 1x mini cacciavite(serve per tarare lo strumento) - manuale utente (lingua italiana non garantita) - 1x panno per la pulizia. Lo strumento si ripone bene all’interno di una statola in plastica rigida(foto allegate). CONCLUSIONI: Premetto che non ho mai usato rifrattometri di alto livello con costi decisamente superiori! Giudico questo strumento che secondo me visto il prezzo è davvero molto valido.. Nel mio piccolo acquario marino di barriera (100lt)non allevo coralli duri o altri organismi particolarmente sensibili, pertanto la precisione di questo strumento relativamente alla salinità e gravità specifica a me sta bene! Ho confrontato i risultati dell’acqua rilevati con il mio strumento con quelli del mio negoziante di fiducia e sono apparentemente uguali! Sono soddisfatto del mio acquisto e mi sento di consigliarlo. Allego le foto e spero che la mia recensione possa tornarvi utile. Buoni acquisti a tutti!

Appareil reçu ce jour. Marche parfaitement. J arrive même à l utiliser avec des lunettes de vue, il faut penser à tourner la lentille pour faire la mise au point. Les données ont l air cohérentes pour mon terrarium avec sa partie eau de mer

Fungerar mycket bra
Användre den till att mäta salthalten i mitt saltvattens akvarie. Den är lätt att läsa av och fungerar väldigt bra.
