The reasonable installation and use of moisture meter in wood drying kilnxingnan
Due to the moisture meter is composed of two same thermometer, often there is error, so the wood drying kilnhygrometer check carefully before installation in good condition, mercury is discontinuous, and check its degree, only two thermometer shows at the same time, the degree of phase can be used.Hygrometer thermal bag can’t pack too thickly, 3, 4 layer is commonly used in medical absorbent gauze advisable. If too thick, is equivalent to the water measured temperature of the water temperature, the other end of the gauze put people in the sink, the location of the tank can’t affect indoor air circulation.
During the period of using, to make the gauze keep moist state.Should regularly to add clean water tank, it is forbidden to its work under anhydrous state caused by moisture meter can’t truthfully reflect the state of air medium. Water tank steel, aluminum or stainless steel are available, and to improve its corrosion resistance ability, prevent the pollution of water quality, shall be affixed to the sink, and pipe water device connected with preparation, and add water device should be keep the same level, with indoor flume and drain and overflow line.
Wet ball bulb and the surface distance should be 3 ~ 4 cm, with is too small, can interfere with wet gauze air flow;Too far away to make wet gauze. Hygrometer faces the airflow is placed in the parts of heat, thermal bags from the dry room wall should not be less than 150 mm.Temperature, hygrometer should be safely easily head-up display part of the observation position, in order to facilitate observation and prevent the parallax. In use process, hygrometer should be check regularly, to ensure measurement accuracy, if discover the abnormal readings, should be replaced in a timely manner.
