Cleanroom environmental monitoring: standards, dust particle counter equipment, and common issues

Clean room environmental monitoring is a key step in ensuring the normal operation of clean rooms and product quality. We will explore the standards for clean room environmental monitoring, dust particle counter equipment, and common issues.
The environmental monitoring standards for clean rooms mainly include ISO 14644-1 and ISO 14644-2. ISO 14644-1 specifies the classification and grading of clean rooms, while ISO 14644-2 provides detailed methods for environmental monitoring of clean rooms. These standards provide guidance for the design, construction, and operation of cleanrooms, ensuring that they can meet specific environmental requirements.

The dust particle counter is the core equipment for monitoring clean room environments. It is used to detect the concentration of dust particles in the clean room air to ensure that the clean room meets the specified cleanliness level. This counter adopts laser scattering technology, which can monitor the particle concentration in clean space in real time and continuously, and has the following characteristics:
It can simultaneously detect the number of particles in six channels: 0.3 μ m, 0.5 μ m, 1 μ m, 3 μ m, 5 μ m, and 10 μ m.
1. Equipped with pump suction active sampling function, real-time monitoring and controllability of sampling flow rate, and adjustable sampling interval.
2. Built in humidity compensation can overcome the impact of humidity on detection accuracy.
3. Choose a long-life air pump, which can have a service life of over 3 years in factory mode.
4. Equipped with a 4.3-inch LCD screen, it presents real-time detection data of each channel clearly.
5. Provide one RS485 output for convenient networking use; Scalable 4G and LORA wireless transmission.
Common issues when using a dust particle counter for clean room environmental monitoring include:
1. Selection of sampling flow rate: Different cleanroom standards and particle counter models may require different sampling flow rates. Therefore, when selecting a particle counter, it is necessary to ensure that its sampling flow rate meets relevant standards.
2. The influence of humidity: Humidity may affect the detection accuracy of particle counters. Therefore, when choosing a particle counter, one should consider whether it has humidity compensation function.
3. Data transmission method: The particle counter needs to transmit the detection data to the monitoring center. When selecting a particle counter, it is necessary to ensure that its data transmission method meets the requirements of the monitoring center.
Clean room environmental monitoring is a key step in ensuring the normal operation of clean rooms and product quality. Understanding the standards for clean room environmental monitoring, dust particle counter equipment, and common issues can help us better monitor the clean room environment and ensure that it meets the required cleanliness level.
