Cleanroom Dust Particle Checking Machine, Flow rate: 2 LPM

How To Choose a Dust Particle Counter for Clean Rooms? Selecting an appropriate particle counter requires evaluating technical specifications against operational needs. Minimum compliance includes adherence to ISO 21501-4 for calibration accuracy and ISO 14644-1 for testing methodologies. Critical performance metrics are particle size detection range (typically 0.3μm to 5.0μm), sampling flow rate accuracy (±5%), and false count rate thresholds. Units must support your cleanroom classification – ISO Class 5 environments necessitate 0.1μm sensitivity, while Class 8 may only require 0.5μm detection. Cost-efficiency extends beyond initial purchase price. Consider sample volume throughput, maintenance intervals, and calibration costs. Units with internal data storage reduce peripheral equipment needs. Integration capabilities with Building Management Systems via Modbus or Ethernet are essential for continuous monitoring. Verify supplier certification documentation, including NIST-traceable calibration certificates and third-party testing reports. Evaluate after-sales support for sensor replacement lead times and local service technician availability. Dust Particle Counter Features: 1. Android system version 7.1, better operation and interaction experience. 2. Built-in temperature and humidity sensor, ambient air pressure sensor 3. The core component light scattering sensor obviously eliminates the stray light in the cavity, and the signal-to-noise ratio is greatly improved. This results in more accurate and reliable measurements. 4. Calculated at 95% confidence level (UCL), the counting results can be converted to m3 and ft3 5. According to the division and regulation of purification level, the purification level is automatically determined, which is convenient to use. 6. With audit trail function, it can be queried, traced and controlled, and it meets FDA 21CFR PART11 specifications 7. Support WIFI and Bluetooth transmission, and data can be uploaded wirelessly; At the same time, it supports U disk to copy data, and does not need to be plugged and unplugged without drivers. 8. Configure the supervision platform, and the test results can be directly and wirelessly transmitted to the platform for long-term and short-term analysis of cleanliness and auxiliary management. 9. Built-in new generation of high-speed thermal printer, you can select the particle size channel you need to print, and print results flexibly. 10. AC and DC dual-purpose, built-in rechargeable lithium battery, environmentally friendly and durable, can support continuous sampling for more than 6 hours. 11. Convenient and simple telescopic gimbal bracket, which is more convenient for installation and sampling operation.
