Classification:

According to the principle, it can be divided into: scattered light method testing (white light, laser), microscope method testing, weighing method testing, DMA method testing, inertial method testing, diffusion method testing, condensed nucleus method testing (CNC), etc. Among them, the photoresist method (shading method) is a commonly used principle.

According to flow rate, there are two types: small flow rate (such as 0.1 cfm, or 2.83 L/min) and large flow rate (such as 1 cfm, or 28.3 L/min).

According to usage: portable particle counter, desktop particle counter, online particle counter, upstream and downstream particle counter, etc.

Divided by channel: single channel, dual channel, multi-channel, etc.

Features:

High precision: The laser particle counter adopts laser technology, which has high measurement accuracy and resolution.

Wide measurement range: It can measure particles with different particle sizes ranging from a few nanometers to hundreds of micrometers.

Real time monitoring: capable of monitoring the quantity and particle size distribution of particles in airflow or liquid flow in real time.

Strong reliability: using optical principles for measurement, less susceptible to pollution and interference.

Easy to operate: usually operated through a touch screen or keyboard, with a user-friendly interface and easy to use.

Application field

Laser particle counters have wide applications in multiple fields, including but not limited to:

Environmental protection field: used to monitor the concentration of particulate matter in the atmosphere and evaluate air quality.

In the pharmaceutical field, it is used to detect the number of particles in sterile workshops, pharmaceutical production lines, and other environments to ensure the safety of drug production.

In the field of chemical engineering, it is used to monitor changes in particulate matter during chemical reactions and optimize production processes.

Food field: used to detect particle contamination in food production environments to ensure the hygiene and quality of food.

Aerospace field: used to detect the amount of particulate matter in engine fuel systems to ensure flight safety.

In summary, laser particle counter is a high-precision, wide measurement range, real-time monitoring, and highly reliable measuring instrument that has been widely used in multiple fields. When selecting and using, product performance and user needs should be fully considered to ensure the accuracy and reliability of measurement results.
