The Bosch GMM 1-15 Professional is a pinless (non-invasive) moisture meter designed for accurate, immediate moisture readings across a wide range of building materials and timber types. Using electromagnetic measurement technology, it reads moisture content in 37 types of wood and 10 types of building material without the need for pins, making it ideal for non-destructive surface assessment. Results are displayed on a 2.4" colour TFT LCD screen with a resolution of 240 x 320 pixels, ensuring clear, easy-to-read output in varying light conditions. The adjustable threshold scale allows you to quickly interpret whether moisture levels are within acceptable limits, while the reference mode lets you compare readings across different areas of a surface or structure. A centre button holds measurements for review, and adjustable sound feedback provides audible confirmation — useful when working in positions where viewing the screen isn't always practical. Rated IP65 for dust and splash protection, the GMM 1-15 Professional is built to perform reliably on demanding construction sites. Its rubber-enforced housing adds further resilience against knocks and drops. Supplied with a protective pouch and two AA batteries, it's ready to use straight from the box. Suitable for drywallers, painters, plumbers, carpenters, facility managers, and architects, this damp meter is a practical tool for checking surface conditions before painting, inspecting drywall, and monitoring timber moisture levels.
