The KQ-4011 large flow 28.3L desktop laser dust particle counter is a new generation product independently developed by our company, breaking foreign monopolies and featuring a simple and elegant appearance. The counter is based on the principle of light scattering and uses photoelectric sensing technology to detect the particle size and count the number of dust particles. Compared to the regular high flow particle counter, this instrument detects smaller particle sizes and can detect a minimum particle count of 0.1um, making it suitable for ultra clean environments of level ten and level one; Suitable for ultra clean scenarios such as electronics, semiconductors, LCD panels, micro/nano processing, aerospace, precision machining, new materials, and research institutes.
1. 28.3L high flow sampling improves sampling accuracy and efficiency
2. 7-inch high-definition large screen with higher resolution and faster response, allowing users to intuitively read cleanliness data
3. Friendly human-computer interaction, simple and direct operation, reducing user learning costs, and improving user experience
4. The body is made of all 304 stainless steel material, which meets the requirements of GMP standards and is not aesthetically pleasing
5. 20000 sets of high-capacity data storage, supporting one click export of PDF files from USB flash drives, and downloading data anytime, anywhere
6. Supports 100 room point preset functions, one click selection, and fast sampling
7. Supports 20 user management, password complexity management, and multi-level permission management
8. Supports audit tracking, log management, queryable, traceable, controllable, and complies with FDA 21CFR PART11 specifications
9. Support calibration reminder function to remind users of timing and measurement, ensuring the normal use of the instrument
10. Imported laser source from Japan, with a lifespan greater than 30000 hours (requires annual calibration)
11. Screen data alarm, equipped with flow sensors for real-time monitoring of flow and real-time self adjustment of flow to ensure stability of flow and accuracy of counting
12. Large capacity high-quality lithium battery, longer battery life, dual use of AC and DC
13. Scalable, with analog input hardware interface, can be externally connected to temperature and humidity sensors/wind speed sensors/differential pressure sensors, etc. (optional)
