The air ion concentration meter is an air (or gas with a presence of ions) that collects the concentration of ions (gas) in the air through a charged parallel polarized electrode plate. The outer two plates maintain a polarized (positive, negative) potential. In the middle is a linear detector board. The pores of the air are 4 MM and the potential of the polarized zone is 1000 V/M. Positive ions can be measured and negative ions can be measured. It is also possible to measure the negative ion concentration of the body, such as cloth, fiber, and the like. Let us introduce the precautions and operation instructions of the air negative ion detector.
Negative ion detector notes :
1. When measuring, keep the air relatively static and not flowing, and the measuring personnel should stay away from one arm;
2. The battery voltage is lower than 7.5V. The battery should be replaced. In standby mode (STANDBY), the battery usage time is about 10 hours. Under the measurement condition (MEASURE), the battery usage time is about 2 hours. Otherwise, the measurement result will be generated. Great error
3, do not continue to start measurement;
4, the reading should take the middle reading of the range of values ​​that appear
Negative ion detector operating instructions:
1. Connect the ground wire of the instrument
2. Select to determine POLARITY at + or - to determine the determination of positive and negative ions.
3, upright instrument, the knob is OFF, the button of the button is placed in STANDBY, then the knob is turned to 19.99×10n;
4, the heat machine for 1 minute, when the number does not change (basically in a center change), press the button to RE-ZERO, and keep 3-5 seconds;
5. When the displayed number is -0.02-0.02, it is stable; if it is unstable, it needs to be re-zeroed;
6. When measuring, press the button of the button to start measuring in MEASURE;
7. According to the displayed numerical value, the knob can be tracked to different range of range; if the number 1 is displayed during the measurement process, it should be adjusted to the range of the larger range;
The above is a brief introduction of the negative ion detector. For more information, please read: Negative Ion Detector
In 2007, Shanghai Bayu ( ) Industrial Co., Ltd. established an offline supply system for laboratory instruments, MRO industrial products, etc. In 2009, it officially launched an online procurement operation platform.
Nut is the essence of the plant part, general nutrition is rich, contain protein, oil, mineral, vitamin is taller, have very good effect to human body growth and development, enhance physique, prevent disease. Preventive effect: nuts are rich in protein, also called long fruit, also called plant meat, it is the most beautiful gift given to human nature, its nutritional value is recognized by the society, it contains zinc, manganese, phosphorus and other human necessary trace elements are very precious to human! Also can regulate the endocrine of the human body, for our brain nerve also has a good regulation function, but also can prevent cancer, cancer. The help to the human is really very big, and economic benefits, is the medicine of human! Experts also found that nut eaters had a lower risk of coronary heart disease. Nuts are good for your body, especially your heart. Nuts are known to reduce the risk of heart disease.
Nuts contain 36.0% protein, 58.8% fat, 72.6% carbohydrate, vitamins (vitamin B, vitamin E, etc.), trace elements (phosphorus, calcium, zinc, iron), dietary fiber, etc. In addition, it also contains monounsaturated fatty acids, polyunsaturated fatty acids, including linolenic acid, linoleic acid and other essential fatty acids of the human body.
