Operation introduction of pin moisture detector
Pin Type Wood Moisture Meter
Also known as: Moisture Meter, Moisture Meter, Humidity Detector, Moisture Meter, Moisture Meter, etc. Digital Wood Moisture Meter is a first-generation wood moisture meter in the category of wood moisture meter. The instrument adopts the current advanced single-chip computer chip core technology. The test data is more accurate, the operation is convenient, the reading is intuitive, and it has 7 gear corrections to make the moisture value more accurate. The instrument has a small design, beautiful appearance, and is easy to carry, and is suitable for rapid moisture determination of various types of wood.
How to operate the pin moisture detector
1. Gear setting method: first press the gear setting button (SPECIES), then press the test button (TEST), at this time the current gear value is displayed, press the setting button continuously, and the gear can be continuously changed until the desired gear.
2. Check before measurement: Set to level 5 according to the above method, then pull out the cap of the instrument, touch the probe on the instrument to the two contacts on the cap, press the test button, if the display shows 18±1, it means the instrument is normal.
3 Measurement: Insert the probe on the instrument into the wood specimen to be measured. Press the test button, the value displayed by the instrument is the average moisture content of the specimen, when the moisture content of the specimen is less than 3, it will display 3.0, and when the moisture content of the specimen is greater than 40, it will display 40, which means it has exceeded the range.
Precautions for wood moisture meter:
1. When using the instrument for the first time, you can change the gear measurement according to the empirical range value of wood moisture, which gear has the smallest error, and then measure at this gear.
2. If the wood moisture to be measured is unknown, the gear can be determined as follows:
First take a wood sample with relatively average water content, measure the water content with the instrument at levels 1-7, and record the measured values of each level. Then the samples were sent into the oven, and the moisture content was determined by the oven drying method. Then compare with the average value of 7 groups, which gear has the measured value close to it, and then the measurement will be fixed at this gear. If the above measurement is unconditional, it is usually recommended to perform the measurement on the 5th gear. However, attention should be paid to the measurement error caused by this.
