The SDS3907 28.3L online dust particle counter is a multi-channel dust particle counter based on the principle of single particle laser scattering. It can accurately measure 6-channel particles including 0.3μm, 0.5μm, 1μm, 3μm, 5μm, and 10μm, which are commonly used in the industry. It supports multiple wired and wireless communication interfaces and transmits data in real time to various intelligent terminals, reducing human involvement. It is suitable for various occasions with cleanliness monitoring requirements, achieving continuous real-time monitoring 7*24h, reducing risks and costs.
The SDS3907 28.3L online dust particle counter is made of SUS304 stainless steel shell material, with a built-in closed-loop feedback control high negative pressure constant flow gas source. The outlet is equipped with a high-efficiency filter, which can effectively avoid pollution to the sampling environment.
● Reliable and stable: Aerodynamic correction, self inspection of light and gas paths, insensitive to vibration, ensuring system reliability and stability
● Stable flow rate: Adopting active sampling method and closed-loop feedback control of constant current gas source, it can support stable, long-term, high negative pressure sampling
● Human computer interaction: 4.3-inch intelligent touch screen, which can set local start stop, sampling mode, periodic sampling, data unit switching, alarm, time and device address, etc
● Data alarm: Optional sound and light alarm function, alarm value can be set
● Counting mode: Supports real-time data display and cumulative data display
● Circuit protection: ESD, overcurrent, overvoltage, anti reverse connection protection
● Communication interface: Standard RS485 communication, Ethernet communication; Optional 4G, WiFi, Lora communication
● Shell material: SUS304 stainless steel
Nova SDS3907 28.3L online dust particle counters are widely used in clean room environments such as the pharmaceutical industry, electronics industry, food processing industry, and precision machining for online particle counting and detection scenarios.
