The instrument is a portable direct reading measuring instrument with light scattering. It has the advantages of fast test speed, high sensitivity, good stability, light weight, low noise, simple operation, and dual use of AC and DC. The function of the instrument is equivalent to the level of the same kind of laser dust meter in foreign countries, and the price is lower than that of the same kind of instruments in China. The instrument is a new generation of intelligent measuring instrument for real-time measurement of inhalable particulate matter concentration in air, such as disease control center, health supervision, environmental monitoring and other departments.
Application places:
◆ Special dust meter for environmental monitoring station
◆ Determination of dust concentration in Labor Department of industrial and mining enterprises
◆ Monitoring of inhalable particulate matter in public places of health and epidemic prevention stations
◆ Environmental monitoring department of the atmospheric dust detection, pollution source investigation
◆ Field test on scientific research, filter performance test and so on
◆ Measurement of field dust concentration and monitoring of dust concentration in exhaust port
◆ Drug manufacturing test
◆ Occupational health and safety testing
◆ Factories need to clean air areas, precision instruments, test instruments, electronic components, food, medicine and other manufacturing processes.
◆ Research institutions, meteorology, public hygiene, industrial labor health engineering, air pollution research, etc.
◆ Dust detection in buildings or blasting sites; site site exposure monitoring
◆ Indoor air quality inspection
三、◆ Measurement range: 0.001~20mg/m3; the two data of PM2.5 and PM10 can be measured at the same time. The advanced multi-channel electronic cutting technology is used without the need to replace the cutting head.
◆ The relative measurement error: less than 10%; sensitivity: 0.001mg/m3
◆ With curve display function: edge measuring and drawing data curve, users can observe the change trend of dust concentration directly through the curve.
◆With statistical analysis function: the instrument can automatically count the average concentration and maximum concentration during the period of measurement, and can query the time of the peak concentration.
◆ Large screen LCD in Chinese display, humanized design, rich display content, LCD backlight display
◆ It has a built-in real-time clock, measured data and time storage, and facilitates user statistics and analysis
◆ Sampling time: the measurement period of each group of data can be set freely within 0~99 minutes, and 10 sets of sampling time can be predisposed.
◆ Data storage capacity: 100 storage areas. Each region can store 1000 measurement records, the total capacity is 100 thousand, and the storage data can be stored for at least ten years. The power failure is not lost.
◆ Can be fitted with a micro printer to print the measurement data at any time and anywhere
◆ It can transmit the measured data to the computer and analyze the data by software
◆ Power supply: built-in battery, AC and DC dual use; imported lithium battery electric core, in the case of sufficient battery power, can be measured for 12 hours in a continuous way.
◆Communication mode: digital signal: RS232, RS485; analog signal (selection):4~20ma, 0~5V
◆ Host size: 320mm * 280 mm * 125 mm;
◆ Host weight: about 1200g
◆ At the same time, two kinds of data of PM2.5 and PM10 are measured, and the range can reach 20mg/m3
◆ Relative measurement error: from less than 10%; the detection sensitivity up to 0.001mg/m3
◆ The trend of concentration change
◆ The measurement period can be set to achieve continuous measurement
◆ Data storage is up to 100 thousand
Imported lithium battery core, continuous measurement for up to 12 hours
◆Digital signals: RS232, RS485; analog signals (selected):4~20ma, 0~5V, to achieve data online or computer transmission
