After a simple "no-salt" calibration, this gives the salinity and temperature of my water perfectly. This is so much better and more reliable than the swing-arm hygrometer.
I've had it for 4 months now, and do a weekly water change. I have not had to change the batteries yet.
Thanks to the previous reviewers upon whose advice I based the purchase decision. This is a terrific addition and you'll want a digital refractometer if you spend any time at all with saltwater aquariums. Highly recommended.
Each time I use this I start off with a little eye dropper of RO/DI water and always get a perfect 1.000 SG reading. Then I do the same method with saltwater and it works everytime. I double checked the first few times with my cheapo hydrometer and it is right on the money.
This is a little on the expensive side...but I wanted something easy, reliable and accurate and this is what I got. So far A+ on this unit. It measures salinity in 3 ways and even adjusts for temperature. I don't think it gets much better than this.
We have thousands of dollars invested in or business and need high quality equipment to help us maintain it.
Easy to calibrate and use.
First of, Read the instructions
Do not try to use under bright light, you will get a error message
And use a soft clean cloth to wipe the glass piece after each use
For those new at changing water I can share my method. I have a 14 gallon nano cube and I change 2 gallons twice a week. I measure out my water in gallon water jugs, similar to milk jugs only they had distilled water in them. I fill them with RODI water for my salt mix. Then I weight out 293 grams of Kent Marine Reef Salt Mix using a gram scale. That brings the salinity to 1.024 (263 grams will bring it to 1.021). Then I pour one gallon of water in a five gallon plastic jug, pour in the salt, cap and invert to mix several times. Then I pour in the last gallon rinsing out my salt container in the process, cap and invert to mix again. This initial mixing puts most of the salt into solution. Then I add a small powerhead and aquarium heater for a few hours and everything goes into solution without any further mixing. Then using two other gallon jugs I empty out exactly two gallons and pour in the fresh saltwater. Works like a charm!

I love this thing. It reads 36 ppt 1.027sg with a 35ppt solution, but that is pretty accurate and within the range of accuracy stated by the manufacturer.Published 4 months ago by Eric
