The KQ-4001 desktop laser airborne particle counter with low flow rate of 2.83L is a precision testing instrument applied in clean environment cleanliness detection.
The product shell is made of stainless steel, combined with professional industrial design. The handle is recessed and placed at the rear (an industry first), with a simple and elegant appearance. It has the smallest size and lightest weight in China. The body adopts a 7-inch touchscreen, which displays detection data intuitively, and the touch operation is simple, comfortable, efficient, and convenient.
Based on the light scattering principle, the core sensor realizes the detection of the size and quantity of suspended particles in the clean environment 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.
Product Features:
• 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.
• Compact size for easy carrying, can be held by hand or used directly on the ground (the height of the air inlet can be adjusted between 0.7-1.4 meters).
• Real-time flow monitoring, using an intelligent algorithm to realize real-time negative feedback automatic flow adjustment for more accurate detection results.
• 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).
• Large-capacity high-quality lithium battery for longer battery life, supporting both AC and DC power supply.
• Expandable, with an analog input interface for external connection of temperature and humidity sensors/air velocity sensors/differential pressure sensors, etc. (optional).
• Optional floor tripod with height adjustable up to 1.4m.
