It combines pin-type and pinless sensing in one compact unit, giving you versatile testing options for spots or larger areas. Clear readings and practical features support informed decisions about dampness, potential risk areas, and next steps for maintenance or remediation planning.\u003c\/p\u003e\n\n\u003ch3\u003eWhat it measures\u003c\/h3\u003e\n\u003cp\u003eThe meter reports a humidity level to indicate ambient dampness, a moisture percentage for wood and materials, and an ambient temperature display. It includes a °F\/°C switch and audible\/visual cues that categorize moisture as high, medium, or low. For wood, the moisture range is 5%–50%; for building materials like concrete and drywall, 1.5%–33% provides a useful basis for assessment.\u003c\/p\u003e\n\n\u003ch3\u003eSensor options and accuracy\u003c\/h3\u003e\n\u003cp\u003eTest surfaces with pin-type probes for precise, spot readings or switch to the pinless flat-pad sensors for broader coverage.
