The KQ-4011 high flow 28.3L desktop laser dust particle counter is a new generation product independently developed by our company, breaking the foreign monopoly 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 regular high flow particle counters, this instrument detects particles with smaller diameters and can detect particles as small as 0.1um. It is suitable for Class 10 and Class 1 ultra clean environments; Suitable for ultra clean scenarios such as electronics, semiconductors, LCD panels, micro nano processing, aerospace, precision processing, new materials, research institutes, etc.
l28.3L high flow sampling improves sampling accuracy and efficiency
l7-inch high-definition large screen with higher resolution and faster response, allowing users to intuitively read cleanliness data
lUser friendly human-computer interaction, simple and direct operation, reducing user learning costs and improving user experience
lThe body is made of 304 stainless steel material, which meets the requirements of GMP standards while maintaining its aesthetic appeal
l20000 sets of large capacity data storage, supporting one click export of PDF files from USB flash drive, and downloading data anytime, anywhere
lSupport 400 room point preset functions, one click selection, fast sampling
lSupports 20 user management, password complexity management, and multi-level permission management
Support audit tracking, log management, searchable, traceable, and controllable, in compliance with FDA 21CFR PART11 standards
lSupport calibration reminder function, reminding users to measure in a timely manner to ensure the normal use of the instrument
l10 years long lifespan imported semiconductor laser diode (requiring annual calibration)
Screen data alarm, with flow sensor for real-time monitoring of flow and real-time self adjustment of flow to ensure stability of flow and accuracy of counting
lLarge capacity high-quality lithium battery, longer battery life, dual-use for both AC and DC
Scalable, with analog input hardware interface, can be connected to external temperature and humidity sensors/wind speed sensors/pressure difference sensors, etc. (optional)
