b.A moisture meter
c.A caliper on the dried paint
d.A pressure gauge on the sprayer
Giải thích
A wet-film thickness gauge, often a notched comb, is pressed into the fresh coating to read the wet mils applied. This lets the painter adjust technique in real time to hit the target and, with the solids content, the required dry film. Dry film gauges are used after curing to verify final thickness on metal.
