Hydrometer Question 2-13-04 (hydrometer)
That chart is off by at least 1 ppt. That table is form a soils hydrometer, calibrated to
69 F A friend of mine made a calculator for us base on the empirical equation. Most floating hydrometers in this hobby are calibrated to 75 F. The Tropic Marin is calibrated to77 F. If it is a swinging arm hydrometer no calibration temp is needed just read it direct. http://www.wymag.org.uk/simon/salinityhr.htm -- Boomer Want to talk chemistry ?
