I'm trying to move from a pinpoint salinity meter to a Hanna meter and confused about what I should use for a conversion factor and Beta factor in the Hanna meter. I guess Beta ranges from 0 (no conversion) to 2. My saltwater aquaria are maintained at 10-12C (deep ocean invertebrates), so we're about 20 degrees below room temperature and need to measure salinity at room temperature when making up new water for water changes but also monitor at the cold temps and it would be nice to just let the meter do the reading accurately without having to consult a temperature/conductivity chart. Any suggestions? Thank you!
