Breathalyzer is a device that uses high-precision sensing technology and intelligent algorithms to accurately detect alcohol concentration. It is mainly used to detect the magnitude of alcohol content in human blood, so as to assess a person's drinking status and risk factor. The main features of this instrument are portable, small size, light weight, simple operation, flexibility and convenience. There are two types of breathalyzer, one is the rapid response type and the other is the long-term monitoring type. The rapid response type is mainly used to detect alcohol concentration over a short period of time, while the long-term monitoring type can continuously monitor changes in alcohol concentration over a period of time.

An breathalyzer works by measuring the concentration of alcohol in a person's blood to determine whether or not a person has been drinking. It typically uses a technique called gas chromatography to measure alcohol concentration. Gas chromatography is a technique based on the separation and analysis of gases that separates alcohol from human blood and determines whether a person has consumed alcohol by measuring its concentration.

A breathalyzer is very simple to use. All that is required is to insert the breathalyzer into a person's finger or earlobe and press the test button, and the breathalyzer will automatically measure the alcohol concentration in a person's blood. The test results are displayed on the tester's screen and can be transferred to a computer or mobile phone via Bluetooth or USB interface for storage and analysis.

A breathalyzer plays an important role in protecting the safety of construction sites, effectively preventing the occurrence of accidents caused by workers working under the influence of alcohol, and at the same time enhancing the safety management level of enterprises and the safety awareness of employees. In addition, breathalyzer are widely used in many fields such as traffic safety, food safety and industrial production environment monitoring, etc. With the development of science and technology, the precision and stability of the instrument has been improved and integrated with intelligent algorithms and remote monitoring and other functions, which has a broad development prospect in the future and the market demand will continue to grow.
