Function characteristics
● 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
Application scenarios
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.
