The SX-L301H type dust particle counter is a new generation of touch-screen handheld devices developed by our company, with a sampling flow rate of 2.83L/min±5% (0.1CFM). The instrument features a 4.3-inch color touchscreen, an elegant and robust design, and is made from full ABS material with a surface that has been spray-coated. It uses a pneumatic pump for continuous and stable operation, featuring ultra-low noise, energy efficiency, and environmental friendliness. It is equipped with an imported digital flow sensor for dynamic and precise control of the sampling flow rate. The instrument can be powered by AC or a large-capacity lithium battery, making it ideal for mobile detection in areas without AC power. The instrument is user-friendly, with a simple operation and a user-friendly interface, enabling efficient and effective detection of suspended particles in clean environments. It is the preferred choice for rapid testing of cleanroom cleanliness in industries such as biopharmaceuticals, electronics, semiconductors, and new energy.
