Bosch GMM 1-15 Professional Pinless Moisture Meter
The Bosch GMM 1-15 Professional Pinless Moisture Meter helps users measure surface moisture quickly and without damage. Pinless measurement technology allows readings without piercing materials, which protects surfaces such as wood, drywall, and decorative finishes. Clear results appear on the bright TFT LCD screen, making it simple to check conditions in real time.
Designed for everyday trade work, the Bosch GMM 1-15 gives reliable readings across a wide range of building materials. It can measure moisture in many wood types as well as common construction surfaces. The adjustable threshold scale also helps users understand moisture levels quickly while they work.
Fast Non-Invasive Moisture Detection
Instead of using pins, the Bosch GMM 1-15 Professional Pinless Moisture Meter scans the material surface to detect moisture beneath. Measurement depth reaches up to 30 mm, which allows quick checks across walls, timber, or floors. Because surfaces remain intact, the tool is ideal for inspections and finishing work.
The integrated reference mode supports accurate comparison between different areas. Users can measure a dry section first and then compare it with nearby areas to locate potential moisture problems. This method helps identify damp zones quickly during inspections.
Built for Jobsite Conditions
Durability matters when working on busy sites. A rubber reinforced housing protects the Bosch GMM 1-15 from impacts while the IP65 rating helps resist dust and water splashes. As a result, the tool continues to perform reliably in demanding environments.
A central measurement hold button makes it easy to capture readings instantly. Audible feedback confirms when measurements are taken, which helps improve efficiency during surveys. With clear readings, strong protection, and simple controls, the Bosch GMM 1-15 Professional Pinless Moisture Meter supports fast and confident moisture inspection.
