Is it a one time use or you can test multiple cars?

You can run dozens and dozens of tests on different cars. Good for many years of use. Works as it was designed to do.

Does this work with any type of coolant?

This product works with any ethylenglycol-based coolant. It does not matter if the coolant is an OAT (organic), IAT (inorganic/synthetic) or HOAT (hybrid).

How accurate is this thing? I just had my coolant replaced and it’s still reading below the recommended temp.

Below is good when it comes to the coolant freezing. Is it reading a low temp, or do you mean it's reading higher than what you need for freeze protection?

Will this work on a semi truck?

As long as the coolant is ethylene glycol based.
