Detects what the human eye cannot see. This versatile tool in an ultra-compact format assists in measuring moisture in firewood, construction timber, and other building materials. It also reliably detects moisture in walls and floors, for example, due to water leaks. The ultra-compact moisture meter features 2 modes for precise moisture detection in wood or cardboard (6-60%) and solid materials like concrete or gypsum (0.2-2.9%). Practical LEDs in red, yellow, and green indicate how critical the moisture level is. Quick and clear: The wood moisture meter displays measurements instantly on the easy-to-read LCD screen without long waits. The hold function allows the display to show the measured value continuously, and automatic shutdown occurs after 15 seconds of inactivity. The temperature reading can be set to either Celsius or Fahrenheit. It comes with a handy wrist strap and a protective cap for the probes and the user, making it convenient for transport in a jacket or pants pocket. Includes 4x LR44 button cells, weight: 41 g, dimensions: 85 x 46 x 16 mm.
