qualifier token a chosen word

condition measured in

also called state it was measured in

The state the fluid was in when a temperature figure was measured — dry, water-contaminated, undiluted, or diluted 50/50 with water. Without it a boiling or freezing point is not comparable and can be dangerously misread: 230 C dry and 155 C wet are the same brake fluid, and 175 C undiluted and 110 C at 50 per cent are the same coolant. One qualifier serves both `boiling_point` and `freezing_point` because it is one question — under what condition was this read — and the four values partition cleanly between the two families that use them.

Condition measured in is answered with one word chosen from the fluid conditions list — the same word shared across every product that uses it.

It is a qualifier of freeze protection — it has meaning only inside a freeze protection statement, never on its own. It belongs with freeze protection to measurement — its measurable, physical facts.

It is answered inside every freeze protection statement, not as a standalone question on a kind.
