Why not just use a meter?

Hi @Tester and others following the thread.
So went to work applying those stuff.
A 2017 Prius coolant tested 0.3 V. Its the factory coolant.
Manual says “Engine coolant: Change every 100,000 miles or 10 years, whichever comes first7. Then 50k miles or 5yrs.”
Thoughts?
2009 Corolla coolant - believe previous owner changed it. It measured 0.01v or -0.01v. The pink fluid looked brownish at times. Perhaps the radiator has sign of rust?
Firestone tested BF with a strip and said its bad - became purple in color.
Voltmeter gave over 9 V - at home test!
Positive to battery. Negative to the Fluid.
They work.
If it turned purple, and you read over 9 VDC with the meter, the brake fluid needs to be changed.

What more do you need and why does it take you so long to do something that should have been done already ?

Indeed they work - having validated, I am now confident about these tools!
Thanks for sharing the videos - I have had small voltages of negative values - I bought some strips and will test them again.
