I am trying to determine what will be the best handheld meter to purchase for my new reef tank? I am leaning toward a combo meter from Hanna that tests for pH, temp, EC and TDS. I've found two slightly different models from them online for $129, but don't know which is going to be more appropriate for a marine tank since it is from a hydroponic supply company.
Model 98129 has an EC range of 0-3999 pS/cm and TDS range of 0-2000 ppm.
Model 98130 has an EC range of 0.00-20.00 mS/cm and TDS range of 0.00-10.00 ppt.
Both have an accuracy of 2% for EC/TDS and .05 for pH. I know that the pH accuracy is pretty good, but I'm not sure how the EC/TDS accuracy stacks up.
Suggestions?
Will I still need a refractometer to feel safe about my salinity?
Thanks in advance.
