4. Core Technologies and Functional Features

4.1 Core Technologies

• Light Scattering Sensing Technology: The core light scattering sensor significantly eliminates stray light in the cavity, greatly improving the signal-to-noise ratio for more accurate and reliable measurements. It uses an imported semiconductor laser diode (service life >30,000 hours) to ensure long-term stable operation.

• Multi-Parameter Sensing Technology: Built-in temperature, humidity, and atmospheric pressure sensors to collect environmental parameters, providing contextual references for measurement accuracy.

• Data Processing & Transmission Technology: Calculates counting results based on 95% confidence level (UCL) and converts them into m³ and ft³ units. Supports multiple data transmission methods for efficient data storage and sharing.

4.2 Functional Features

1. Multi-Parameter Monitoring: Integrates temperature, humidity, and atmospheric pressure sensors to monitor environmental conditions alongside particle counts.

2. Audible & Visual Alarm: Triggers audible and visual alarms for particle counts exceeding user-set thresholds via configurable alarm parameters.

3. Enhanced User Experience: Runs on Android 7.1 operating system with a 7-inch color touchscreen, enabling intuitive and smooth operation.

4. Automatic Grade Determination: Automatically judges cleanroom grades based on cleanroom classification standards, simplifying operation.

5. Versatile Data Transmission: Supports WiFi, Ethernet (wired) for cloud platform uploads, and USB flash drive for data copying (driver-free plug-and-play).

6. Cloud Management Support: Comes with a supervision platform client; test results are directly transmitted to the cloud for long-term/short-term cleanliness analysis and auxiliary management.

7. Flexible Sampling Modes: Offers scheduled sampling and continuous sampling to meet diverse testing needs.

8. Large-Capacity Data Storage: Stores 10,000–100,000 data records, with query and export functions for historical data tracing.
