Guangdong OSEN-AQM-8000 real-time alarm monitoring system Shenzhen dust dust concentration alarm ..

OSEN-AQM-8000 is measured using laser scattering theory of dust concentration in the leading domestic and international works to ensure that the dust concentration in real-time online monitoring. Optional wired / wireless transmission equipment, can easily perform network-based network monitoring; equipment is small, easy to move. The main technical indicators 1, the configuration 40mm filter line sampler; 2, with replaceable cutters particles PM10, PM5, PM2.5, PM1.0 and TSP for selection; 3, direct-reading dust concentration (mg / m3), one minute the result 4, large-screen LCD display, Chinese menu; 5, detection sensitivity: (L) 0.01mg / m3; (H) 0.001mg / m3. 6, repeatability error: ± 2% 7, measurement accuracy: ± 10% 8, measuring range: (L) 0.01 ~ 100 mg / m3; (H) 0.001 ~ 10 mg / m3. 9, measurement time: standard time of 1 minute, 0.1 points and has a manual transmission (which can be arbitrarily set the sampling time). 10, with public spaces monitoring mode, the main technical characteristics of atmospheric environmental monitoring 1. The design of the main technical characteristics of the particles can replace the cutter, to achieve a PM10, PM5, PM2. 5, TSP is compatible with a variety of particle separator cutter. 2. The design of the filter sampler, to achieve a continuous monitoring dust concentration compatible with the sampling filter, you can analyze the collected particulate matter and composition determined mass concentration conversion coefficient K value of the property. 3. Using a laser light source, the mass concentration of particulate matter is not affected by the conversion factor of color. 4. Large-screen LCD display, to achieve the Chinese menu. 5. Design the constant current controller to ensure a constant flow sampling, cutting the curve correctly. 6. With built-in optical scattering board to ensure high stability. 7. The air curtain has special protection to avoid dust on the core component - contamination of the optical system, to ensure high reliability. 8. The instrument automatic zero adjustment by computer software, improve measurement accuracy, convenience to users. 9. The instrument is designed sampling timing mechanism can be timed according to the set sampling time, time to start and shut down, and the resulting data can be processed by micro-printer data recording or import PC machine, leaving the instrument is adapted to the atmosphere of respirable particulate matter continuous monitoring. 10. The instrument can be set alarm threshold concentrations exceeding the dust, when the dust exceeded the automatic audible alarm, or send the signal to the control center to monitor. 11. The instrument is designed analog output interface, when the evaluation of air purifiers, can draw its cleaning efficiency evaluation curve. 12. In addition to a dust monitor for indoor public places and for general measurement mode environment monitoring time sampling mode, the newly added labor health model, in this mode, according to industrial enterprises health standards (GBZ1-2002) and work Workplace Hazardous Factors Exposure Limits (GBZ2-2002), to calculate the time-weighted average (TWA) and short-term exposure allowable concentration (STEL). 1. The power line and transmission functions restart function: When the power is restored the instrument, you can automatically enter the measurement status; 2. power protection: the instrument parameter settings and measurement results are not lost in the long-term power outages; 3. Remote time function: via a wireless transmission network for clock monitoring equipment will be on time. 1 pair of multi-center software features of the system software for online work, but also work offline, through the dust monitor instrument RS485 bus nodes while online, real-time capture any dust monitor on the bus data, upload history, drawing curves and other functions; while offline can check records, drawing historical curve, concentration calculation. Terms of the agreement functions as follows: 1. Manage an RS485 bus, support for total instrument address is 253 units. 2. Acquire dust monitoring equipment, real-time data. 3. Management data collection, including real-time graphics and historical data plotting, storage and query, print. 4. Management RS485 device nodes on the bus, the center of the parameters of the device can be configured; communications equipment over 30, or a total of more than 500 meters distance of each communication need to add the relay station. 5. concentrations exceeding the alarm. 6. The automatic, manual control (dust suppression equipment) command output (optional). 7. equipment failure logging. 8. The setting upload data (communication protocol to be determined); (all uploads;. Excessive concentration value can be set [] data upload) conversion 9. concentration value (input data set K value, humidity, weather conditions determine the concentration value;) 10. Dust Monitor automatically receives data transmitted from and displayed in the display box, you can graph the data in a very intuitive way to display it. 11. Historical data query, the query results in the display shown in the box, or you can graph data displayed very intuitive way. Environmental monitoring equipment optional two gases and particulate matter sensor monitoring device consisting of a portable monitoring stations. The gas sensor of choice and I have many years experience working and have many years experience in the production of domestic manufacturers of sensors, the advantage of timely delivery, experienced, professional and technical staff to do security service. Particulate monitoring equipment to choose our products, the range of 0.001-10 mg / m3; in view of environmental testing in the TSP measurements have changed much closer to human health impact of respirable particulate matter PM10, most Chinese standards on particulate matter measurements are to PM10 excessive, but due to the recent severe haze, now more oriented to monitor PM2.5 particle dust.
