Lost Salt - SOLVED

Yeppers, Analytic Scientific on Bandera. If you are going to get one there, give me a call.

I don't see the right range on their website. They may have to order it.

Here you go.

I'm going to go to a floating hydrometer. The most ccurate in my opinion. The only real negative is that you have to adjust for temp. but that just means reading the adjustment off a chart.

That's how we did it in the lab.

Gary, are those better than this?

Steve, I had the same problem. I would calibrate my pinpoint every two weeks and it still was reading off right after a calibration. Dang pinpoint, my salinity went up to 1.028. Anyway, I think I am goimg with a Refractometer.

Steve, I think the point is that a floating Hydrometer is a good baseline to have around. It never needs calibration, other than temperature conversion from a chart. Works on bouyancy of saltwater.

I have a refractometer and swing arm. I use the swing arm when making up new saltwater until I get close then switch over to the refractometer for getting it the same as the tank.

However, when you are measuring an electrical current across the probes as is the case with a pH or salinity meter, it is a problem.

This kind of makes you wonder if you might need to take out the grounding probe and clean it off every so often.

As long as a floating hydrometer is clean it is the most accurate thing out there. Someone posted soething a while back about accuracy problems with hydrometers. I think it was Larry.
