eSHa Marinomat vs. Seatest hydrometer
Started up my salt tank again. Got out my trusty Seatest hydrometer (10years old) and set the salinity to 1.024. Everything going great. Splurged on a new meter and got the hydrometer from eSHa Marinomat. WHOA... salinity was 1.030. So now I start double checking readings making sure there are no bubbles sticking to the arms or needles. The Marinomat read about 5 100th's higher. Lower the salinity to 1.024 for the eSHa Marinomat, now the Seatest reads 1.019 The eSHa Marinomat is suppose to adjust for water temp but I can't imagine a difference that big. Will the Seatest meters go bad? or could the eSHa Marinomat be off. Guess I need to get a third party reading.

Yes to the seatest going bad.
Possibly on the Esha. I own one and am pleased. I would look into a good floater or a refractometer to be sure. But I think stability is the best, not just the readings.

i have the esha marinomat,and it gives the same readings as my seatest.the sea test is easier to use ,so i dont even use the esha.

I'm with Paul on this one. I used the eSHa once a long time ago and the Seatest is probably in everybodys house. I have seen 4 Seatest dip into the same tank and all 4 come up with different readings.
If you plan to be in this hobby long. Buy a refractometer. I had one of the large floating hydrometers like Paul mentioned and they are VERY good but there also hard to use and very fragile. Mark |

You know, I havent checked my sal in atleast a month. Like I said, its more a stability issue IMO than a exact number. If things are doing well, and you are "in range" then IMO your fine with any measuring device as long as you try and maintain that reading with that device.

I like the deep six hydrometer. It seems to be easier to use than the seatest. My sea test reading did not seem likely considering the appearance of my tank. Those are the only two I have compared.

Well.... Here the latest update. The instruction for the eSHa Marinomat say to way 2 days for the water to "cure". After adjusting the salinity to 1.022 I check with both meters a day later and they were on 1000th apart. The eSHa Marinomat read 1.022 and the Seatest read 1.0205~ This is with in specs...or so says Robert Fenner. Most hydrometers are calibrated at 60 degrees and will vary by 1000 with every 10 degrees. Guess I'll pay attention to the instructions next time. Between the two I think I like the eSHa Marinomat best. thx all for your input.
