Why it matters for coating performance

Applying coatings outside specified environmental conditions can reduce adhesion, shorten service life, and increase the risk of early failure. The Elcometer 308 helps you verify critical conditions in seconds—supporting better decisions on site, fewer rejects, and more consistent coating quality.

Key benefits & differentiators

• Designed for extreme heat: purpose-built for environments where surface temperature may exceed recommended coating limits.
• Rugged, sealed construction: suitable for harsh sites; dustproof and waterproof with fully sealed sensors.
• Hold/Release function: one-button “hold” to freeze readings on-screen for logging, then “release” to continue measuring.
• Bright backlight: easy reading in dark or confined spaces.
• Quality-focused workflow: quick checks of RH and Ts to improve coating reliability and reduce costly rework.

Typical applications

• Environmental checks before and during coating on steel and concrete substrates.
• Outdoor work in direct sun and high-heat conditions.
• Industrial maintenance, marine, infrastructure, and demanding QC environments.
• Confined-space inspections, supported by the backlit display.
