Online VOC monitoring system

VOC (Volatile Organic Compounds) are organic compounds that are easily volatilized at room temperature and pressure and enter the atmosphere, including hydrocarbons, alcohols, ketones, aldehydes, esters, phenols, etc. VOC not only causes air pollution and malodor problems but also harms human health and the ecological environment, such as carcinogenesis, teratology, sensitization, etc. Therefore, monitoring and control of VOC is one of the important parts of environmental protection work. Therefore, the monitoring and control of VOC is one of the important contents of environmental protection work.

Online VOC monitoring system is a kind of equipment for real-time monitoring of VOC concentration in the air around industrial parks or factories, which can timely detect and warn the problem of VOC exceeding the standard, and provide scientific basis and technical support for the environmental management department.

Components of Online Voc Monitoring System

  1. Sampling probe: Used to extract samples from the air and remove moisture and impurities through filters, condensers, and other devices.
  2. Sensor: Used to analyze and measure the collected samples, usually a Semiconductor TVOC Sensor is used, which can detect a variety of VOC components, such as total hydrocarbons, total non-methane hydrocarbons, benzene, and so on.
  3. Data Collector: Used to receive the signal output from the sensor and process and store the data, which can realize the functions of real-time data display, alarm, and remote transmission.
  4. monitoring software: it is used to analyze and manage the data uploaded by the data collector, and it can realize the functions of data query, statistics, chart generation, report printing, and so on.

The working principle of the Online VOC monitoring system

  1. The sampling probe takes a sample from the air and removes moisture and impurities by means of a filter, condenser, etc. The sensor analyzes and measures the collected sample and outputs an electrical signal proportional to the VOC concentration.
  2. the sensor analyzes and measures the collected sample and outputs an electrical signal proportional to the VOC concentration.
  3. the data collector receives the signal output from the sensor, processes, and stores the data, and realizes the functions of real-time data display, alarm, and remote transmission.
  4. the monitoring software analyzes and manages the data uploaded by the data collector, and realizes the functions of querying, statistics, generating charts, and printing reports.

Functional features

  1. real-time monitoring: real-time monitoring of the concentration of a variety of VOC components in the air, and timely detection and early warning of VOC exceeding the standard.
  2. accurate measurement: using advanced sensing technology, with high sensitivity, high precision, high stability, and other characteristics, can accurately reflect the changes of VOC in the air.
  3. automatic calibration: with the automatic calibration function, it can automatically adjust the working parameters of the instrument according to the environmental conditions to ensure the accuracy and consistency of the measurement.
  4. automatic protection: with an automatic protection function, it can automatically cut off the power supply when encountering power failure, over-voltage, over-current, over-temperature, and other abnormal conditions to prevent damage to the instrument.
  5. Dustproof and waterproof: with a dustproof and waterproof design, it can adapt to harsh environmental conditions and ensure the normal work of the instrument.
