With the advancement of modern technology, dust particle counters have been widely used in fields such as environmental monitoring, healthcare, and industrial production. However, there are various brands, types, technical parameters, and other aspects of particle counters on the market, which can be overwhelming. What factors should we consider when choosing?

1. Measurement range: Select a particle counter with an appropriate measurement range to ensure accurate monitoring of the count. The traditional particle counter has a particle size range of 0.3 μ m to 10 μ m, and a single device can cover six channels, making it suitable for medical rooms, electronic workshops, and other areas with high cleanliness levels; For workshop environments with large particles, a particle counter with a larger monitoring particle size range can be selected, such as a particle counter with a particle size range of 0.3~35 μ m.

2. Sampling flow rate: Common sampling flow rates include 2.83L/min, 28.3L/min, 50L/min, and 100L/min. In general, in environments with high air cleanliness, it is necessary to choose a larger sampling flow rate to ensure accurate detection of the number of particles. The larger the sampling flow rate, the more particles can be detected by the particle counter. However, particle counters with larger sampling traffic usually have higher prices. Therefore, when selecting the sampling flow rate for particle counters, it is necessary to comprehensively consider factors such as actual needs, measurement environment, and budget.

3. Accuracy and Resolution: Accuracy and resolution are important indicators for measuring the performance of particle counters. Choosing a particle counter with an industrial grade laser light source and calibrated with a single standard particle often results in higher counting efficiency, accuracy, and resolution. You can also check if the equipment has a calibration certificate from the metrology institute to evaluate the accuracy of the monitoring data.

4. Reliability and Durability: Choose a particle counter with aerodynamic correction design and optical and pneumatic self checking functions to reduce the impact of equipment vibration on monitoring data and ensure data stability; Moreover, it is best to use industrial grade components for the equipment, which can pass the quality certification of formal institutions, have higher durability, and can be used stably for a long time, reducing subsequent operation and maintenance costs.
