To determine the moisture level of woodspecial moisture meters are used. To date, there are needle, contact and chip modifications. On the parameters they are quite different. However, there are not so many manufacturers in the market of hygrometers. The main companies can be attributed primarily to EMCO and "Valkom". It is worth an average of a good moisture meter on the market around 1500 rubles.
If necessary, you can make a moisture meter forwood with their own hands. Its scheme includes a sensor of dielectric type. Also, the device requires a compact generator. The parameter of the limiting frequency must be no more than 30 MHz. Contacts for a self-made model is more expedient to select needle. Yet, to make a moisture meter for wood with your own hands, you need a three-channel chip.
The permittivity of the device must bebe in the area of 3.5 F / m. The microprocessor for the model is selected with an impulse amplifier. Probes most often are of a tubular type. It is more appropriate to select a display line. Compared to textual analogs, it is simpler. The electrodes of moisture meters are directly capacitive. In turn, the catcher will need to be set resistive. The last choice for the model is accumulators. In this case, you can use ordinary finger batteries.
Contact moisture meters for wood are goodsuitable for working with plywood, as well as parquet.

Many modifications are equipped with thermal sensors. The calibration function is available on many devices. There is an average quality moisture meter in the region of 2 thousand rubles.
Needle moisture meters for wood are used,usually for pine or spruce. Sensors in all configurations are used dielectric type. If we talk about the parameters, the measurement accuracy mainly fluctuates around 0.2%. The maximum humidity threshold of devices does not exceed 35%. The minimum allowable temperature for models is 0 degrees. Microprocessors in many devices are used with amplifiers. There is an average moisture meter for wood (needle) in the region of 1200 rubles.
Probe moisture meters for wood mainlymakes the company "Valkom". If you believe the opinion of experts, then the parameter of relative error is extremely low. Generators in devices are used with a frequency of 20 MHz. Directly catchers are installed resistive type. The minimum humidity threshold of models does not exceed 5%. In turn, the resolution of the devices is at the level of 1 PH. Displays are often of the lower case type for moisture meters. Some modifications are equipped with thermometers. The calibration function in devices is quite rare. Find a model of this type on the market can be for 2 thousand rubles.
In the construction field presented moisture meteris in great demand. It is ideal for working with parquet and panels. Also, this moisture meter is equipped with a thermometer. Another advantage of the modification can be called the presence of needle-type contacts. The microcircuit of the model is provided by a three-channel manufacturer, so the measurement of wood moisture is fast. Electrodes are used capacitive type.
The maximum humidity threshold does not exceed 40%.In size, this moisture meter is very compact, and belongs to the class of portable devices. According to the documentation, its mass without batteries is 80 g. The resolution of the model is at 1.3 PH. The maximum allowable temperature of the model is exactly 35 degrees. In the cold presented the device is prohibited to use. Measurement accuracy fluctuates around 1.4%. In stores, this device can be found for 2100 rubles.
This moisture meter is equipped with a sensordielectric type. If you believe customer reviews, the resolution of the device is quite high. Directly generator model is used at 22 MHz. According to the documentation, the maximum allowable temperature is 40 degrees. The display in the device is text type.
Batteries are used for 1 mAh, thereforegrabs them for long. In this case, the catcher is a resistive type manufacturer. If you believe the opinions of experts, then problems with determining the importance of slivers do not arise. The maximum measurement depth is 10 mm. The user can buy the moisture meter for 1400 rubles.
Specified moisture meter for solid wood amongOther models have a high resolution parameter at 1.3 PH. All this suggests that the device works fine at temperatures below 10 degrees. In this case, the measure of accuracy of measurement is at around 0.2%. The maximum permissible humidity threshold is 30%.
The catcher in the device is providedresistive type. The chip is used three-channel, and the generator is installed low-frequency. According to the documentation for the device, the case is provided with an IP 62 protection system. The presented model weighs exactly 80 g. There is enough memory for 30 thousand measurements. You can buy it for 1500 rubles.
Specified moisture meter for wood reviews inmostly gets good. The main advantage of the model lies in the compactness. If we talk about more constructive features, it is important to note that his contacts are using probes. Directly sensors in the case there are two. Thus, the measurement accuracy is quite high.
Зонд в устройстве производителем предусмотрен tubular type. The resolution of the instrument ranges around 1.3 PH. The maximum humidity threshold, according to the documentation for the moisture meter, is 35%. Buy today this model can be for 2 thousand rubles.
В строительной сафре представленный влагомер is in great demand. First of all, we should mention the quality generator, which is installed with a frequency of 33 MHz. In this case, the sensor has a dielectric type. Contacts in turn are used needle. If you believe the opinions of experts, then the measurement accuracy of the model is high.
For parquet and panels it can be used.The minimum allowable temperature of the device is 0 degrees. The resolution index is 1 PH. Directly the catcher in the device is installed resistive type. The microprocessor is used with a pulse amplifier. The maximum humidity threshold of the device is at around 40%. You can buy this moisture meter for only 1400 rubles.
Указанный портативный влагомер отличается protected enclosure. The sensor has a low frequency type. In turn, the contacts are needle. The calibration function in the presented instance is. The ambient temperature with this device can be determined. It is also important to mention the high resolution of the model.
