TFA HumidCheck Mini – Compact Wood Moisture Meter for fast, reliable readings

Small in size and big in performance, the TFA HumidCheck Mini delivers instant, trustworthy moisture readings in wood and common building materials. Its pin-type sensor measures directly where it matters, helping you decide when timber is ready to process, when firewood is fit to burn, and when building substrates are safe to cover. With two dedicated measurement modes, a clear backlit display, and simple one-button operation, this pocket meter is the go-anywhere tool for carpenters, flooring installers, joiners, DIY renovators and energy-conscious households seeking accurate results in seconds.

• Protects your projects — Verify that timber, parquet and subfloors are within acceptable moisture levels before installation to minimise warping, cupping and adhesive failures.
• Firewood you can trust — Check logs before burning to support cleaner combustion and better stove efficiency by avoiding overly wet wood.
