VOC detection is a technically demanding, costly, and personnel intensive task. It is an important aspect of implementing VOC online monitoring or off-site monitoring at fixed pollution source discharge outlets. The online and off-site monitoring of VOCs will directly affect production, daily life, and environmental quality.
The portable VOC detector provides a better and faster solution for VOC monitoring.
1. Equipped with temperature compensation function, the ambient temperature can be set according to temperature compensation, and the ambient temperature can be set according to the operating environment temperature of the device.
By using the environmental temperature compensation function, users can obtain stable temperature, ensuring the stability and accuracy of the portable VOC detection system operation. Its built-in temperature compensation function can automatically adjust the ambient temperature to compensate for the operating temperature of the VOC online monitoring system equipment; And the built-in temperature compensation function can automatically adjust the operating temperature of the device. This device not only has the function of compensating for the specific environmental temperature of the device's operation, but also can set temperature control according to the actual temperature of the device's operation (such as switching to a constant temperature state in case of abnormal temperature). This is also one of the reasons why the device can achieve continuous automatic monitoring during operation. This can save customers a significant amount of capital investment.
2. The portable VOC detector has the functions of automatic sampler, gas chromatography sampler, and automatic adjustment of the sampler.
Can achieve quantitative sampling of VOCs in the air. There are various methods for VOC analysis (gas chromatography/mass spectrometry, atomic absorption) and multiple sample analysis methods (acid-base neutralization, infrared spectroscopy analysis). Portable VOC detectors can meet the needs of various industry usage scenarios. The instrument has reliable and stable performance, equipped with dual program processors. It can ensure the stability of data under working conditions (such as temperature changes, etc.), greatly reducing the workload of data analysis in the later stage.
3. Equipped with a temperature compensation module, the portable VOC detector can automatically adjust the temperature according to the ambient temperature.
When automatically adjusting the temperature, the temperature at the VOC monitoring point cannot exceed 35 degrees. When the VOC concentration exceeds the standard limit, the instrument will automatically sound an alarm. Avoiding the impact of high temperature on VOC emission concentration.
4. The temperature can be freely set according to user needs.
It is a fully automatic gas detector that can perform real-time online monitoring of areas with high VOC emissions such as production workshops, petrochemicals, and chemical industries in the industrial field, and can be monitored online through automatic adjustment programs. The instrument adopts an expandable high-sensitivity Voc sensor and a microcomputer control system. Users can change the measurement range as needed at any time. Built in rapid temperature detection module to meet the needs of users with different requirements. And it can also automatically turn off the Voc sensor and cut off the heating pipeline during measurement.
5. The portable VOC detector adopts international advanced design concepts, and the instrument is designed with high-quality chips to inject stable and reliable protection measures into the instrument.
There are multiple ways to achieve real-time VOC content analysis based on different locations. At present, there are three main methods for VOC detection: gas chromatography, electrochemical (LC-MS), gas chromatography, and laser Raman spectroscopy (LRD). Gas chromatography and gas chromatography-mass spectrometry have their own shortcomings; Laser Raman spectroscopy, due to its high sensitivity; The advantages of wide applicability and not limited by space are widely used in VOC pollution monitoring. With the continuous advancement and innovation of technology, the removal rate of VOCs will also become higher and higher.
