What is the principle of fat measuring instrument What is the measurement principle of human fat sca

The principle of the fat measuring instrument is measured using the bioelectrical impedance method. That is, there is an ITO conductive film on the surface, and the weak bioelectricity is circulated in the body without damage, which is measured by the BIA bioelectrical impedance method.

The basic principle is that since body fat conducts little electricity, while body components such as muscle and water do, body fat analyzers can calculate the ratio of body fat, water, and other tissue components by measuring the body's bioelectrical impedance.

The correct way to measure the content of human body fat, that is, the fat rate, is to submerge the human body in the water, measure the drainage rate (volume), and then find the specific gravity of the human body according to the weight, and then infer the fat rate of the human body. But this approach is not very practical in everyday situations.

The human body contains about 70% water, most of which is found in blood, lean meat and internal organs, while fat contains very little water. The water in the body has a low resistance due to the dissolution of various components, but the fat has a high resistance, so the ratio of fat and water in the human body affects the resistance of the human body.

There are the following precautions when using:

1.After an intense workout.

2.After sauna or bathing.

3.After excessive alcohol consumption.

4.Drink plenty of water and 1-2 hours after meals.

5.Do not use in pregnant women.

6.People who wear or have medical electronic devices, such as pacemakers, should also avoid using them.

The body fat scale is a weighing meter that can measure fat and moisture in addition to body weight, and there are sensors on the market that measure body fat with two materials: ITO membrane and electrode sheet.

The principle of the human fat scale is that muscle contains more water such as blood and can conduct electricity, while fat does not conduct electricity. Since the channel conductor of the current in the body is the muscle, the weight of the muscle can be determined by the difficulty with which the current passes, and the proportion in the body can be determined.

Studies have found that when a certain frequency of electrical signals passes through the body, the fat part has a higher "impedance" value than the muscle and other tissues of the body. When a safe electrical signal of a specific frequency passes through the human body, the electrical signal will change to varying degrees depending on the value of the "impedance" of the human body.

Principle: Muscle contains more water such as blood and can conduct electricity, while fat does not. Since the channel conductor of the current in the body is the muscle, the weight of the muscle can be known from the difficulty of the current passing, and it can be judged that the proportion of body weight is higher in people with less muscle.

Correct health concept: a healthy body lies in the balance of fat in the body, and excessive fat accumulation is harmful to the body and leads to various diseases. Body fat is an important part of the human body, and it has important functions and roles in the human body, such as providing energy, protecting internal organs, maintaining body temperature, assisting in the absorption of water-soluble vitamins, and participating in human metabolic activities.

However, excessive fat can affect human health, leading to diabetes, cardiovascular and cerebrovascular diseases, etc. In addition, patients with obesity often face various troubles such as heat intolerance, affecting body shape, and fatigue. Therefore, doctors and experts recommend keeping the body shape within a certain range.

With the improvement of people's living standards, health issues are becoming more and more important, which also promotes the development of the science of measuring body composition.

According to the above principle, the electronic fat scale uses the electrodes on the surface of the scale body to contact with the user's legs, and measures the human body resistance (bio-impedance) through a certain safety current. Then, based on the input user data and the measured body resistance, using the formulas obtained in our extensive experiments, we can accurately measure body components such as body fat percentage, body water percentage, human muscle percentage, bone weight, etc.

It is mainly used to determine the quality judgment index --- fatty acid value of grain (including corn and rice), and is also suitable for the determination of fatty acid value of other grains and grain products.

Fat analyzer NAI-ZFCDY-2Z is a fully automatic crude fat analyzer designed according to the principle of Soxhlet extraction and in accordance with the national standard GB T1472-2008. Compared with other similar products, this instrument is simple to operate, can automatically realize extraction, rinsing, pre-drying and other functions, the user only needs to weigh the sample, and the instrument has automatic calculation and printing functions, after the test is completed, the experimental results can be automatically printed. The instrument adopts touch LCD screen, intuitive and easy to operate, fully considering the accidental damage caused by the leakage of ether to the human body, which is the full embodiment of the design concept of Haineng always putting safety first.

During operation, the heating temperature can be adjusted according to the different boiling point and ambient temperature of the reagent, and the sample is repeatedly soaked and extracted during the extraction process, so as to achieve the purpose of rapid determination.
