Hi,
Anyone ever try to build one of these? I got one recently from an auto parts store but it's the turkey baster type, and the 'cold' fluid measurements are not very informative as shown here (and note 3 balls floating with pure distilled water already):
All fluids room temperature, about 75 to 80 degrees F.
Starting concentration with distilled water: 0.000 percent
After 0 pure antifreeze additions: 00 percent, 3 balls floating
After 1 pure antifreeze additions: 20 percent, 4 balls floating
After 2 pure antifreeze additions: 33 percent, 4 balls floating
After 3 pure antifreeze additions: 43 percent, 4 balls floating
After 4 pure antifreeze additions: 50 percent, 4 balls floating
After 5 pure antifreeze additions: 56 percent, 5 balls floating
The test concentration is given above in percent, and the number of balls floating with that concentration. Granted the water should be hot, but i cant get it hot in my car because the only access to the water is through the overflow tank, which doesnt get hot.
So i was thinking an electronic one would be interesting. If we had a way to measure something about the water mixture, we could correlate that to the degrees of protection, and calibrate it with pre mixed known concentrations of pure antifreeze.
I dont want to buy another tester because it's probably just as inaccurate. Maybe an electronic one would be more accurate and reliable.
Any ideas?
