PT-90D Pocket digital wood hygrometer Is a series of digital display and multi-file tree in the PT series, which is suitable for the rapid determination of the moisture content of the board and various boards.The microcomputer chip technology uses the software to automatically calibrate the error and improve the resolution precision and the reading is more intuitive Convenient. At the same time to expand the measurement range, an increase of 7 file tree correction. In order to facilitate the user to determine whether the instrument itself is in good condition, the instrument on the cap to add a test standard. The instrument has a user wood tree tree curve customization and software calibration And the use of functional software upgrades. In addition to the appearance of further reasonable and beautiful. Use more convenient, more portable is the characteristics of the instrument.
First, the main performance and technical indicators
1. Moisture measurement range: 5-40%
2. The resolution of the measurement: 1
3. Measurement error: ± 1%
4. Tree repair gear: 7 files
5. Display: large LED digital display;
6. Overall dimensions: 145 × 65 × 28mm
7. Ambient temperature: - 10 ~ 40 ℃
8. Weight: 160 grams
9. Power: 6F22 type 9V battery 1 section.
Second, the operation method
1, before the inspection:
Unplug the instrument cap, touch the probe on the two contacts on the cap, press the test switch, if the display is 18 ± 1 (tree repair gear is 5), then the instrument is in a normal state.
2, tree stall setting method:
According to the measured wood, according to the recommended schedule to check the gear should be set. Hold down the tree set button, and then press the test switch, this time will display the current tree file stall settings and the bottom right of the decimal point display , Press the tree set button to change the stalls to the desired position, release the two buttons, set the finished. After the boot will keep the set gear until the change again. Note: set the test button do not let go The default position of the instrument is 5, and the tree setting button can be used to check the current setting.
Insert the electrode probe into the wood specimen to be measured. Press the test switch, LED digital tube indicates the data for the average absolute moisture content of the specimen, the measured value< 3时显示3. 鬆开测试开关, 电源自动关闭.
Third, pay attention to matters
1. This instrument is recommended for wood trees to amend the stalls in the table below.
2. Determination of unspecified stalls:
First, take a block to keep the balance of water content of the tree to be determined species of wood samples, with the instrument were measured tree set in the 1 ~ 7 file when the indication value, respectively, calculate the average record. , And then measured by drying method of water content.Then compared with the seven groups of the average, take the value of the closest to the appropriate tree species correction stalls, the future can be used as a reference set.
If the above test can not be carried out, it is recommended to put it on the fifth gear, but pay attention to the measurement error caused by the above.
3. Within six months from the date of shipment, in case of product quality problems, (without human damage), free warranty, one month replacement .Test test cycle is generally one year.
Fourth, tree species revised stalls Schedule Species
New HK-90 Products:
Water below 10, the resolution of 0.1%
HK-90Wood moisture meter for wood fiber material, moisture content of 3% -40%Of the objects, such as bamboo products, wood, veneer, sheet metal and other types of wood moisture content of the rapid determination.
The product uses single-chip computer chip technology, a key to measure no gear, the internal automatic calibration of various errors through the software.Test on the addition of the test standard.
Resolution below 10 is 0.1%, better than the general product.
