Description

Technical Field

[0001] This utility model relates to the field of particle detection technology, and in particular to an online particle counter. Background Technology

[0002] Currently, there are many shortcomings in domestic particle counter technology. On the one hand, the sampling range and sampling accuracy are limited, and signal saturation or misjudgment is prone to occur in high-concentration particle environments, making it difficult to meet the needs of complex working conditions. On the other hand, the communication method is singular, which cannot realize flexible data interaction and remote monitoring. In addition, the market has long been monopolized by foreign industry giants such as Lighthouse and Metone. Their products are not only expensive, but also require regular calibration and maintenance, resulting in heavy maintenance costs and manual management burdens for users.

[0003] Meanwhile, existing particle counters are susceptible to interference from environmental factors such as temperature, humidity, and pressure, affecting data accuracy and requiring additional compensation and correction. Some handheld devices rely on manual inspection and cannot achieve full automation. Low-end domestic products have poor performance stability and are significantly inferior to imported high-end equipment. Furthermore, in complex environments, particulate matter interference can easily lead to measurement errors, posing a risk of data deviation and seriously affecting the reliability of test results. Therefore, we need to upgrade and modify existing technologies to overcome existing problems and shortcomings. Utility Model Content
