ZR-7022 type environmental dust continuous monitor Introduction
The ZR-7022 type environmental dust continuous monitor adopts the principle of β-ray absorption weighing to automatically and accurately measure the TSP, PM2.5 or PM10 particles captured on the filter membrane, and automatically monitor the environmental TSP, PM2.5 and PM10 continuously. concentration. The instrument is small in size, easy to carry and install, has dustproof and rainproof characteristics, and can work automatically continuously for a long time outdoors. It is widely used in routine environmental air quality monitoring, environmental assessment, scientific research, emergency monitoring, and environmental air monitoring station data comparison.

The β-ray absorption weighing + DHS (Dynamic Heating System) principle is used to directly measure the mass concentration of the particles without being affected by the physicochemical properties of the particles, without correction, and providing accurate data in real time in all weather.
The sampling station is separated from the inspection station to effectively avoid pollution and interference of the pollution source to the metering system.
The paper transport mechanism moves the paper in one direction, which effectively avoids the defect that the double-station paper strip is easy to break.
DHS (Dynamic Heating System) is built in to reduce the interference of environmental changes on the measurement results.
The movement protection transparent door design reduces the impact of environmental abrupt changes on data accuracy due to operation such as opening the door guidance data.
Dynamic temperature and humidity compensation ensures accurate measurement of semi-volatile nitrates and organics.
The wide temperature industrial touch screen is convenient and quick to operate.
Automatically measure parameters such as temperature, humidity and air pressure, and automatically convert the standard state sampling volume.
The instrument can automatically store historical test data, can be printed on site or exported with a USB flash drive.
With digital and analog output interfaces, it is easy to connect to the data acquisition instrument for network transmission.
With 4G wireless communication module, it can remotely query the working status of the instrument and real-time measurement data.
The instrument has the function of automatically saving the data after power off, and keeps running before the power is turned off after the call;
The instrument has independent test procedures such as broken tape, filter paper exhaustion and mechanical failure; the instrument automatically alarms when there is a problem.
Built-in lithium battery, able to run continuously for more than 8 hours, to meet various monitoring needs. Technical parameters
Relative error: ≤±2.0%
Resolution: 1μg/m3
Accuracy: ±10%
Measuring range: (0 ~ 10000) μg / m3
