Product Description: Material: Plastic Color: Shown as Picture Operating Temperature: 0-40 degree centigrade Storage temperature: -10-50 degree centigrade Measurement Accuracy: 0.1% Electrical conductivity measurement: 2% Protection level: IP20 Measuring range: 0-80% Rh Food: 1 x 9V 6F22 Battery Product Size (W x L): Approx. 53 x 138 mm / 2.1 x 5.4 inch Product thickness: approx. 31mm / 1.2inch Package Weight: 70g Package Included:1 x Wooden Moisture Meter Description: This durable portable moisture meter is designed for checking materials that absorb water. By penetrating 2 sharp pins, it can accurately measure the humidity of different kinds of materials, such as wooden material, building materials and other soils, and the measuring range is 0-80% RH; Conductivity measurements: 2%; Accuracy: 0.1%, it also has many advantages, such as easy to red LCD display, automatic power off without operation after 2 minutes, etc. Nice product at a good price, worth buying. High precision measurement: Perfect for wood, timber, logs, cardboard, paper, concrete and many types of walls. With sensitive electrode tips, the accuracy is within 2%. 4 Modes: You can switch the different modes according to 4 groups of wood, including about 50 species of wood, which makes the measurement more accurate. Useful Futions: Large LCD display with value hold function to display measurement results; auto shut-off for less battery cost (battery included). Practical Design: Made of ABS plastic for superior durability, sliding touch on both sides. Compact size and lightweight. Comes with a protective case. Wide measuring range: You can also test the building material, different building materials with different measuring ranges, such as concrete plaster walls (1, 4% -7.4%), anhydrite wall (0% -4.1%), cement plaster (0.8% -5.1%), limestone mortar (0.4% - 3.7%), brick (0.7%), % -8.0%. 5%). Note: When the humidity value is lower than the minimum measured value shows ''0'', and beyond the maximum measured value shows "LO".
