Product Description

Ideal for aquariums and marine monitoring, this device measures the salinity of water.
Specific Gravity (D 20/20) and parts per thousand are the two scales used to measure the product.
Temperature compensation is automatically applied.
A hard case, a dropper, a screwdriver, a user manual, and a cleaning cloth are all included.
The main component is made of chromium and is extremely durable.

Questions & Answers

Is this something that can be used in hydroponics?

It's used to see if the saltwater fish tank is working properly.

I'd like to see if I could use the brackish canal water for irrigation. Is this a working tester? Is it true that I should check the canal's salinity?

Yes, brackish water has a pH level of 0 to 1. 05:30 a.m. to 30:30 a.m. P

What is included in the package?

The refractometer, case, and a small screwdriver for adjusting it are all you get. Unless something has been added since we purchased ours a year ago. It won't let me post a picture, which I would like to do.

Hello, I purchased calibrating fluid and set my refractometer to sg 1 using it. 026, but it reads 1 when tested with distilled water. What is the reason for this?

RODI water is what I use to test everything.

With this, you can purchase the calibration fluid
4/5

Make certain to purchase and test the calibration solution before using it! When I first got it, I tested it with distilled water and it seemed to be spot on, but my aquarium's salinity readings were far higher than I expected. So I bought some calibration test fluid, which revealed that the refractometer needed to be adjusted. My aquarium's salinity was 1. after I adjusted the refractometer. 026 is the expected result. I had it independently tested as well, and the refractometer now reads exactly the same as the verified test; I love it now that it's calibrated!.

Excellent quality, precise readings, and ease of use Refractometer of good quality and ease of use
5/5

br>When you first get it, make sure to adjust the focus by turning the eye focal (best seen in bright light). br>I recommend getting the salt calibration solution. (worth the money)br>Seems to give very accurate readings. br>Save a lot of money and buy it here on Amazon for only $20 instead of $30 or more at your local pet store, where you'll almost certainly get the same exact product made in the same exact factory and country but rebranded under a different label.

Without the hefty price tag, this is a high-end product
5/5

This refractometer was purchased as a more accurate alternative to a hydrometer for determining salinity. First and foremost, I'd like to point out that I did purchase the calibration solution (which was sold separately) along with it. It is possible to calibrate with distilled water, but I decided against it. This refractometer came with a cute little plastic case, as well as the following accessories: a cleaning cloth, two droppers, and a small screw driver (in case the calibration needs to be adjusted). I test the salinity in my saltwater tank once a week, as well as when I mix up extra seawater, with this refractometer, which is very easy to use and looks and feels like a high-end instrument without the high price tag. Despite the fact that I use the calibration solution to ensure accuracy, I've never had to adjust it. Even when I use it (I'm not always the most careful with my things), this little guy stays spot on. ) I strongly advise anyone who is serious about their tank to get this.

If it isn't properly adjusted, your reading will be inaccurate
5/5

This is fantastic, but you'll still need to purchase an instant ocean hydrometer to ensure that your readings are consistent. The instantaneous ocean hydrometer is always correct. By hitting the white dial with your knuckle, you should be able to remove the bubbles. So, as soon as your instant ocean displays a measurement, you're ready to go. Compare it to the refractometer and make any necessary adjustments to the refractometer.

After a string of Amazon purchases that appeared to have fake reviews, this is a quality product that has restored my faith in Amazon
5/5

The feedback on this site is genuine. This was a lot of fun to use when I was setting up my Hawaiian Red Shrimp shrimp tank, which requires brackish water with a pH of 1. 010 ; The refractometer allows me to easily read this. Calibration liquid is simple: get some Kirkland (Costco) bottled water that says distilled water (it may say with minerals for taste, but this has no bearing on the meter) and calibrate to 0. My meter was already set to zero when I received it. 00, so all that's left is to start mixing marine salt with distilled water and fiddling with the refractometer. br>br>I had a lot of fun measuring salt water, despite the fact that it appears to be a dull doctor's toy. Haha.

I just received my refractor, and it's a fantastic product
5/5

It included everything that was mentioned in the production description. I then used the calibration solution I had ordered to calibrate the refractor. The refractor had been removed from its box. 1. was the initial reading. 024 if you're using the calibration solution The refractor has been set to 1. The calibration fluid is number 026. After that, I put my water to the test. The temperature of the water was exactly what I had anticipated. This refractor is expected to last for a long time. In any light, it is heavy and easy to read. Anyone with a marine aquarium would benefit from this product. I'll check back later to see if the refractor's calibration has held.

Even if you have a calibration solution, do not put your trust in this
3/5

In a reef tank, it is completely unreliable for reading salinity. This thing has been calibrated three times. A calibration solution was used four times. It has a value of 0. The salinity in my tank slowly dropped until I was on the verge of a tank crash because the actual lever was 010 higher than the actual lever. br>br>I'm still undecided about two of my hammers pulling through. One was a golden hammer, which had been a dream coral of mine; now, like my anemone, my dreams have shriveled and died.

It's ideal, and it's incredibly simple to use
5/5

Continuity. I couldn't make up my mind whether to get this or one of the float arm meters, or both. This is where it all began. It's the only thing I'll ever require. It functions admirably. It is extremely simple to operate. A few drops of water on the glass, the plastic lid closed, and the eye piece aimed at a light source = very easy to see exact salinity on scale (clear line shows the salinity on the meter inside). I use brackish tanks and it works perfectly. Wipe down the glass surface to dry it and put it back on the shelf until next time. It matches known samples (a new water/salt mixture) and repeat checks of the same source. This makes me extremely happy.
