3. Product Features
◆ Utilizes beta-ray and DHS (Dynamic Heating System) principles to directly measure particulate matter concentration, automatically and continuously monitoring ambient PM10 or PM2.5 concentrations; particulate matter sampling flow rate: 16.67 L/min;
◆ Portable integrated design, unaffected by environmental conditions, requiring no correction, providing accurate data in real-time around the clock, dustproof and rainproof, allowing for continuous automatic operation outdoors;
◆ PM2.5 cutter performance: 50% cutting particle size Da50 = 2.5 μm ± 0.2 μm, geometric standard deviation of collection efficiency σg = 1.2 ± 0.1;
◆ Suitable for continuous monitoring of particulate matter PM2.5 and PM10 in ambient air; gaseous pollutants SO2, NO2, O3, CO, and TVOC concentrations;
◆ Modular design, low failure rate, easy maintenance, strong expandability, uses high-quality detectors, stable measurement, safe and reliable, accurate data.
◆ Highly integrated design; different analytical factor modules can be arbitrarily combined, suitable for large-scale gridded sampling.
◆ Intelligent design; includes testing procedures for filter paper breakage, filter paper depletion, and mechanical failures, with fault alarm and self-diagnosis functions.
◆ Utilizes a 7-inch wide-temperature industrial touchscreen for convenient and quick operation.
◆ Automatically measures parameters such as temperature, humidity, and air pressure, and automatically calculates the standard state sampling volume.
◆ Automatically stores historical test data or exports it via USB flash drive.
◆ Equipped with digital and analog output interfaces for easy connection to a data acquisition instrument for network transmission.
◆ Equipped with a 4G wireless communication module, enabling remote querying of instrument operating status and real-time measurement data.
◆ Automatic data recording; automatically saves current data after a power outage and automatically resumes operation from the state before the power outage upon power restoration.
◆ Intelligent control; allows real-time viewing of dynamic monitoring data; supports various chart styles such as line graphs and bar charts for simple and intuitive operation; includes alarm, latitude and longitude (BeiDou), and query functions.
