Brake fluid tester teardown
🕑 Added 2024-10-01 04:37:10 +0000 UTCA look at a brake fluid tester for the usual glycol based brake fluids used in vehicle hydraulic braking systems.
This took a lot longer to reverse engineer than expected, because it worked in a completely different way than I anticipated.

Very interesting circiut. Thank you Clive!

A fun way I amazed the guys at work one day was to tell them I would freeze water at room temperature. I stuck a cup of water inside the container that used a vacuum pump to remove air from some chemicals we used. As the pressure went down, the water boiled furiously until it froze. I have no idea if the water vapor messed up anything with the vacuum pump, so we won't talk about that. ;-)

I badly worded what I meant. Ta

Err, no "The boiling point increases with increased pressure up to the critical point, where the gas and liquid properties become identical. The boiling point cannot be increased beyond the critical point. Likewise, the boiling point decreases with decreasing pressure until the triple point is reached." That's why you can't make decent tea at high altitudes, as the low air pressure makes the water boil at a lower temperature.

I SWORE you said "vape fluid tester" and we know where that would lead.

I wish that tool had been around back in the 1980'and 90's when I was changing my cars more often than my underwear. (urrghhh!! :) )

In addition to how Clive mentioned water changes the compression level of the fluid and lowers the boiling point because of this (water boils at lower temperatures when compressed.
