Dësen elegante Design weist d'Fleur de lys, eng stiliséierter Versioun vun enger Irisblumm, déi souwuel als dekorativen wéi och e symboleschen Emblème vu bal all Zivilisatiounen an der Geschicht benotzt gouf. Et ass besonnesch mat der franséischer Monarchie verbonnen an ass en dauerhafte Symbol vu Frankräich. De Fireback ass en onverzichtbaren Deel vun der Kamäinstraditioun an Europa zënter dem 15. Joerhonnert. D'Kolonisten d'Traditioun an Amerika an haut kënnt Dir dëse klassesche Touch vun Eleganz a Geschicht op Ären eegene Kamäin addéieren. Firebacks sinn entworf fir um Buedem vum Häerz ze raschten, awer Fireback Supports oder Féiss kënnen och benotzt ginn fir dëse Fireback oprecht ze halen an et aus dem Häerz z'erhéijen wann extra Héicht gewënscht ass. All eis Firebacks sinn entworf fir ze benotzen souwuel mat Gas Logbicher an Holz verbrannt Kamäiner.

Nice but kinda hard to read

Excellent choice

I'm using this unit to measure the salinity in my fish tank and for the first time I really know the real value of this important parameter. At first I was using a regular plastic hydrometer and was trusting the results I was getting, but then I bought a second hydrometer and the readings were totally different from the first one. That's when I realized that I needed more precision, and this unit is of course more expensive, but the accuracy you get is worth the extra money. It turned out that the salinity in my tank was way too high and was the reason for several problems I was having with the aquarium. The unit it's extremely easy to calibrate , all you need is destilled water and 10 seconds of your time, and is also very easy to use.

Dishonest seller -- NOT Extech RF20 refractor

I searched and searched looking for upscale instrument and thought this would fit the bill. I thought I was buying an very good quality refractometer judging by the reviews. I did not even bother to try it as it is no better than one for half the price. The package insert says nothing about were it is made, what firm made it, address, email, contact, anything. Save your money. You get the impression you are getting a higher quality instrument, but this is just a chintzy product with a case, like you would get buying a tool at Harbor Freight. Arrive poorly packaged for mailing too. Way over priced. Returning. UPDATE: As I suspected: This is a Chinese knock-off. Below is the link to what you will get. It is NOT an Extech instrument. I have not heard from the seller. This hacks me off. Will ask Amazon for immediate refund. [...]

Long Overdue

First let me say this is an absolutely excellent product. I finally know the exact salinity of my tanks in seconds. There are some great things that come with this Refractometer that are not mentioned in description. It comes with a little bottle of distilled water as well as a mini flat head screw driver to calibrate before your first use. It also comes with a nice mini microfiber cloth to wipe the prism between uses. This is by far the most accurate way to measure the salinity of your tanks water and I can assure you that you will not be disappointed.

Saved my fish and corals

I used a hydrometer before this and noticed I always got 1.026 even when I haven't put in water for daily evaporation and then my anemone died and as soon as I got this it said my salinity was at 1.030, very close to killing everything. Very accurate, very easy to use, not messy and doesn't spill water every where like hydrometers do. Love it and plan on buying another if I ever need to.

A useful tool to measure plant health and nutrition

As a small-scale urban farmer I need feedback about the health of my soil and, consequently, the health of my plants. The Brix refractometer tells me the percentage of dissolved solids in the plant fluids. This is an indicator of both the mineral and sugar content. The higher the percentage the more nutrition in my plants. Happy to report that soil and plant health is good and steadily improving. A very valuable tool.

A must have

If you have a saltwater tank you need to have one of these. A hydrometer won't do. The instructions are clear and it is easy to calibrate. One drop of distilled water is all it takes and you are up and running.

Perfect.

This refractometer is great for keeping track of the salinity of my brackish puffer fish tank. Very accurate, and the price was great! No need to look for something more expensive. This was a great buy and I would definitely recommend it to anyone.
