Description
   ONETEST-100S series high precision air PM2.5, PM10, TSP detection unit is specifically designed for the humid and dusty environment, a linear air quality testing instrument, in the continuous and reliable work has significant characteristics, with excellent environmental tolerance. The instrument detection data is accurate, small humidity influence, small volume.

 Main applications:
Schools, shopping malls, hospitals, buildings, construction sites, roads, tunnels, stockyards, garbage dumps, scenic spots, chemical plants and other occasions.

Product features:
● Long service life: using laser light source, the longest working life of up to three years;
● High resolution: the minimum diameter of resolution particles up to 0.3 microns, good repeatability, error less than 5%;
● Wide working humidity range: 0 ~ 95% RH can work normally and stably;
● Fast response speed: the data update frequency is 1Hz, and the measurement start time is less than 30 seconds, which can realize continuous online monitoring.
● Easy integration: provide 433 MHz or LORA wireless communication mode and 485 wired output, real-time data upload is easy to be integrated in iot devices.
● Related wireless communication products, the detection data can be uploaded to the cloud through the gateway, remote monitoring, data collection, display, analysis, storage, application, release, and intuitive generation of visual calculation results in the management end;
● Compact structure: the product adopts aluminum alloy material design, durable, suitable for wall installation and use, simple operation, effectively reduce the manual working intensity;
● The unique intake design ensures that the aerosol collection is stable, not affected by humidity and large particle dust, and extends the working life of the instrument.
● The system maintenance is simple and convenient, and the maintenance workload is small, saving the later maintenance costs
