1、 PT-90E Pin Type Wood Moisture Meter _ Wood Moisture Detector Usage Characteristics

Purpose: This moisture meter is a digital display version of the PT-90 series, suitable for rapid determination of the percentage moisture content of wood fiber materials with a moisture content of 5% -40%, such as bamboo products, wood, wooden boards, and other items.

Features: This product adopts single-chip computer chip technology, discards all analog potentiometers, and automatically calibrates various errors internally through software. The original LED diode display with a measurement resolution of 2 has been improved to an LED digital display with a resolution of 1, which enhances resolution accuracy and makes readings more intuitive and convenient. At the same time, it also expanded the measurement range.

In order to facilitate users in determining whether the instrument itself is in good condition, a testing standard has been added to the cover of the instrument. This instrument has the ability to customize tree species curves for users and upgrade software calibration and usage functions.

In addition, the instrument is further reasonable and aesthetically pleasing in appearance. The characteristics of this instrument are more convenient to use and lighter to carry.

3、 PT-90E Pin Type Wood Moisture Meter - Operating Method for Wood Moisture Detector

1. Pre measurement inspection

Remove the cover of the instrument panel, place the probe into contact with the two contacts on the cover, press the test switch, and if it displays 18 ± 1, it indicates that the instrument is in normal condition. If the battery indicator light flashes alternately with two decimal points, it indicates that the battery is depleted and needs to be replaced with a new battery in a timely manner.

2. Measurement

Insert the electrode probe into the test specimen to be measured, press the test switch, and the data displayed on the LED digital tube is the average absolute moisture content of the specimen. When the measured value is less than 5, it displays 0; when the measured value is greater than 40, it displays AA, indicating that the range has been exceeded. Test completed, release the test switch, the power will automatically turn off Save energy and protect instruments for longer periods of use.

Jingtai Instrument Knowledge:Wood waterDividers are generally divided into two categories: induction type wood moisture meters and pin type wood moisture meters. The working principle of the pin type wood moisture meter is to measure the resistance between two points of wood, and then convert and display the data in the form of data. Its advantage is that it is cheap, but the accuracy is not too high. After measurement, there will be small needle holes on the surface of the wood, which are often used in measurement fields with low requirements. The working principle of the induction type wood moisture meter is electromagnetic wave (high-frequency) induction,The instrument is equipped with a natural frequency, and the frequency transmitted into the machine through the sensor varies depending on the moisture content of the measured object. The difference between the two frequencies is converted into current through a frequency current converter, and then converted into digital display through an analog-to-digital converter; Its advantages are higher measurement accuracy and non-destructive, even if the wood surface is painted, it can be measured without damage, especially suitable for rapid determination of moisture content in furniture, flooring, wooden doors, etc.
