No I do not. If I remember I could not find one that would read in the range I needed but I could be confusing with something else.

What type of circuit do you use to control voltage to the fuel pump?
Are you using a standard pwm?
I am not sure but a few years ago when I looked into it, the concentration we are using were not on the scale or when it did it was to expensive. Do some research and let us know what you find. I have stayed with a hydrometer. Some lab grade ones cost as high as $40 but a simple battery hydrometer is in the range and accurate enough for some where around 3 to 12 dollars US.

TDS meters are useless with electrolytes, they max out with the lowest level of electrolyte (less than 1%) hydrometers are more practical.
Edit; That is, all the TDS meters that i have ever seen read in PPM Parts per million. There MIGHT be TDS meters that read in PPT/ thousands but i highly doubt it.

Any battery hydrometer will work but here is a link to ACE hardware it has the temperature compensation on it.

Now the cheapest lab type hydrometer I can find is the 15 V 0887. You will also need a narrow cylinder to use this. They cost almost as much as this hydrometer.

Here is the link for the cylinder.

very helpful thanks.
Is there a significant difference between the regular and lab grade?
Which would you recommend?
