What reading precision must SFRM thickness gauges be capable of reading to?

Measuring sprayed fireproofing thickness needs enough resolution to catch small but important deviations from the design thickness. You’re verifying that the material reaches the intended thickness within permitted tolerances, and those tolerances are tight enough that being able to read in 1/16-inch increments lets you distinguish between common thickness levels and spot under- or over-application. If the gauge only reads in larger steps, like 1/8" or 1/4", you could miss a small shortfall or excess, which matters for safety and code compliance. While finer gauges exist, 1/16-inch is the standard reading precision required for SFRM thickness checks, making it the best choice for reliably confirming the coating meets specifications.
