Fulistech particle counter

Fulistech particle counters deliver accurate detection, stable performance, and reliable data, providing efficient airborne particle monitoring solutions for pharmaceutical, semiconductor, medical device, and cleanroom applications.
Features of our airborne pparticle counters

An intuitive interface and simple workflow help you complete particle measurements quickly and efficiently.

The instrument automatically alerts you when measured particle levels exceed preset limits.

Automatically records key operations and test data for easy data traceability and quality management.

Automatically determines the cleanliness level based on measurement results, improving testing efficiency.
Designed for Consistent Particle Sampling
Fulistech airborne particle counters operate at a nominal sampling flow rate of 2.83 L/min, providing a defined sampling condition for cleanroom particle monitoring and contamination control. Built-in flow detection helps monitor the sampling flow, while the flow detection accuracy is subject to further technical confirmation. This allows you to select particle monitoring equipment based on clearly defined operating parameters.


Individual Functional Testing Before Delivery
Every Fulistech particle counter undergoes functional testing before shipment to check the operation of its key functions. This pre-delivery inspection helps identify functional issues before the instrument reaches your facility, giving you greater confidence during installation, commissioning, and routine use.
Built-In Data Storage for Monitoring Records
With built-in data storage, Fulistech particle counters can retain measurement records for subsequent review, depending on the model and its storage settings. This feature helps you organize particle monitoring results and supports routine cleanroom monitoring and quality control documentation


Practical Quality Assurance for Your Application
By combining a defined sampling flow rate, flow detection, pre-delivery functional testing, and data storage, Fulistech focuses on the practical requirements of particle monitoring. You can evaluate the instrument against your sampling needs, operating procedures, and documentation requirements before making a purchasing decision
FLS airborne particle counters ensure reliable testing solutions through rigorous quality management


Fulistech implements a structured quality management system covering incoming material inspection, production process control, product assembly, performance testing, and final inspection. Every testing machine and laboratory testing instrument undergoes functional testing before delivery to help identify potential issues and ensure that essential functions operate as intended.
For our airborne particle counters, the nominal sampling flow rate is 2.83 L/min, with built-in flow detection and data storage to support routine cleanroom particle monitoring and contamination control.
Additional performance verification, including sampling flow accuracy, particle counting efficiency, zero-count level, measurement repeatability, and continuous operation stability, can be specified according to the instrument model and verified test results.
By focusing on product-specific inspection procedures and measurable performance requirements, Fulistech provides reliable particle counting instruments, precision material testing equipment, and customized laboratory testing solutions to help you improve quality control efficiency, reduce measurement-related risks, and meet your application requirements.
