Voltcraft FM-80 Medidor de humedad de materiales con sensor de aguja y función inductiva para madera y materiales de construcción VC-14432275

With a dual measurement system combining pin-type resistance and non-invasive inductive sensing, the Voltcraft FM-80 delivers precise moisture readings across wood and building materials. Its inductive mode scans up to 40 mm deep without surface damage, while the pin mode offers ±2% accuracy for wood. The backlit LCD shows moisture percentage, ambient temperature, min/max values, and adjustable alarms, making it an indispensable tool for construction professionals, woodworkers, and restoration experts.

Overview

The FM-80 is engineered for versatility. Choose pin-type measurement for exact moisture content in wood and building materials, or switch to inductive mode for quick, non-destructive screening of walls, floors, and timber. Eight wood groups and dedicated building material groups ensure calibrated results across common substrates. The device auto-calibrates to ambient temperature and includes a hold function to freeze readings in tight spaces.

What stands out

• Dual measurement: pin-type (0–99.9%) and inductive (0–53% wood, 0–99.9 relative building materials)
• Inductive depth of ~40 mm allows subsurface moisture detection without probes
• High accuracy: ±2% (pin wood), ±4% (inductive)
• Backlit LCD with min/max, data hold, and adjustable moisture alarm
• 8 wood groups and dedicated building material groups for tailored calibration
• Auto power off after ~5 minutes to conserve battery
• Powered by 3x AAA batteries (included)
