The KQ-4010/4050/4100 desktop laser airborne particle counters with high flow rate are a new generation of products independently developed by our company, featuring the smallest size and lightest weight in the industry, with a simple and elegant appearance.
Abandoning the commonly used LCD dot-matrix screen on the market, this product takes the lead in adopting a 7-inch IPS intelligent touchscreen, combined with a human-computer interaction UI, making the operation more efficient and greatly improving the user experience.
At the same time, led by a postdoctoral team from the University of Science and Technology of China, the company has realized the accurate detection of airborne particles through precision photoelectric sensing technology.
This instrument is widely used in clean scenarios such as pharmaceuticals, electronics, hospital operating rooms, aerospace, precision machining, and food industries, and has the characteristics of good stability, high measurement accuracy, elegant appearance, and easy use.
• High sampling flow rate of 28.3, 50, 100L/min, improving sampling precision and efficiency.
• 7-inch high-definition large screen with higher resolution and faster response, allowing users to intuitively read cleanliness data.
• User-friendly human-computer interaction with simple and direct operation, reducing user learning costs and improving user experience.
• Full 304 stainless steel body, meeting GMP specification requirements while maintaining aesthetics.
• Large-capacity data storage of 20,000 groups, supporting one-click PDF file export via USB flash drive for data download anytime and anywhere.
• Supports preset functions for 400 room points, enabling one-click selection and quick sampling.
• Supports 20-user management, password complexity management, and multi-level authority management.
• Supports audit trail and log management, which can be queried, traced, and controlled, complying with FDA 21CFR PART11 specifications.
• Supports custom switching between 6 channels/2 channels (0.5μm, 5.0μm).
• Supports calibration reminder function to prompt users for timely metering and ensure normal use of the instrument.
• 10-year long service life imported semiconductor laser diode (calibration required annually).
• On-screen data alarm, equipped with a flow sensor for real-time monitoring and automatic flow adjustment, ensuring flow stability and counting accuracy.
• Large-capacity high-quality lithium battery for longer battery life, supporting both AC and DC power supply.
• Expandable, with an analog input hardware interface for external connection of temperature and humidity sensors/air velocity sensors/differential pressure sensors, etc. (optional).
