Moisture Meter » Calibration & Accuracy

Keep drywall healthy by learning to measure moisture the right way. This guide explains how pin-type and pinless meters work, when to use each, step-by-step testing on drywall, what readings mean, and how to spot leaks and mold risk. You’ll also get pro tips for calibration, maintenance, and combining thermal imaging with moisture mapping to prevent costly damage.

Understand how moisture meters work and when to use each method. This guide explains pin vs pinless, capacitance and TDR, screening vs acceptance for concrete (ASTM F2170), and how to read %MC/%RH correctly. Includes calibration, common mistakes, and a practical buying checklist with tool recommendations.
