SunGrow Aquarium Refractometer, 7.6 Inches, Measure Salinity of Water, Remarkable Accuracy, Includes Calibration Tool, Ensures Overall Health of Plant and Marine Life, Easy and Clear Reading

Description:

  • Specifically Designed Refractometer For Saltwater Aquarium --- The algorithm is made specifically for testing seawater and saltwater. This is different from a standard refractometer which is not calibrated to check salinity of aquarium water and will give an error in your readings.
  • Automatic Temperature Calibration --- The calibration process should be carried out with both the room and the instrument at 68° F. The refractive index of a liquid changes with temperature. Due to the automatic temperature calibration, any changes in ambient temperature from 50° F- 86° F will not affect the accuracy of the reading.
  • Easy And Clear Reading For Saltwater Aquariums And Reef Tanks --- The refractometer comes with a focus adjustment on the eyepiece, this will give you clarity of the optics and a sharp line for easy reading.
  • Comes In A Solid Case Includes Pipette And Calibration Tool --- This refractometer is not only built extremely well, but it comes with a durable hard case for easy storage of the refractometer when not in use. It also includes a calibration tool and a pipette.
  • Keep Your Fish And Plant Life In Optimal Well-being --- Pure saltwater is crucial for the vitality of your marine or reef aquarium. Use this refractometer to measure the salinity of the water, the target level of salinity in a reef tank should be 35 ppt.

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

    5.0 out of 5 stars A must have for salt aquariums

    k. · 10 January 2024

    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.

    Good for what I need and calibrated correctly as tested with calibration fluid

    R.C.P. · 10 December 2018

    This is a great product and what was a fantastic price, disappointed it has doubled in price but still reasonable considering prices of similar items. Tested against more expensive refractometer and hydrometer and against one at lfs and is totally accurate and has stayed accurate since first calibration.

    rifrattometro è davvero semplice

    M.C. · 27 March 2025

    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 hatteBisher 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. ;-)
