Measuring range 5% - 40%-Large digital LCD display-Accuracy:+/- 1%-Readable data storage-Powered by 9V battery (included) and low battery indicator-2 sensor pins in use-The sensor pin can be replaced according to the application-Dimensions: 130 L x 64 W x 32 H (mm)-Compact and convenient, easy to use and carry1. The excellent digital hygrometer with 2 test probes includes a 9V battery, a suitcase and a plastic cover, which can protect the pin, so that the hygrometer can remain intact even without using wood. It also includes a user guide.2. The large LCD screen of the LCD screen moisture detector can immediately display the moisture content. In order to check the stored wood, the water content should be clearly and easily specified. A very practical tool for wood and general construction engineering. If necessary, you can press the "H" key to keep this display on the screen.3. Humidity measurement range The humidity measurement range is from 5% to 40%, and the accuracy is 1%. Resolution: 1%. If you have a wood burner, this is a good supplementary tool, because you need to burn wood/firewood with water content of about 20% or less to avoid flying sparks. Burning logs with moisture content higher than 20% will cause chimney smoke and fire risk.4. The hygrometer is easy to use. Simply push the sharp teeth into the wood to clearly display the humidity reading. This means that all logs that are not fully stored can be put back to the special wood processing plant, and only dry logs can be used.5. The water content of materials can be identified, from hardwood (such as teak and oak) to medium-strength wood (such as pine and mahogany), to softwood (such as plywood and cork), and building materials (such as concrete, cement, carpet, sub-floor and dry wall). It is applicable to carpentry, construction or agriculture. It is very suitable for locating moisture on the carpet or floor bottom.
