PC-3A laser dust monitor measuring PM2.5 and PM10 Price

PC-3A laser dust monitor (upgrade version) First, the major technical indicators 1, respirable particulate matter measuring range: 0.001 ~ 10mg / m3; 2, measuring PM2.5 and PM10; 3, relative measurement error: ≤ ± 10%; 4, the detection sensitivity: 0.001mg / m3; 5, sampling time: 8 pre-set sampling time, each measurement and stop time from 0 to 99 minutes a user can be set; 6, the data storage capacity: The system is divided into 10 data storage areas, each 200 sets of data, a total of 2000 sets of data storage zone 10; 7 is connected with the printer: mini-printer, connect only to the host via a data line, anytime, anywhere direct printing, no longer because there is no AC power The trouble can not be printed; 8 Power supply: built-in battery, AC and DC; in the built-in battery is fully charged, the continuous measurement of 8 hours. 9, the host Volume: 230mm × 120 mm × 42 mm; 10, Weight: 600g ;, II Product Overview This instrument is the Centers for Disease Control, health surveillance, environmental monitoring and other departments in real-time to quickly measure the air of respirable particulate matter concentration of new generation of intelligent measurement instruments. The instrument is portable direct reading light scattering measurement instruments. With a test speed, high sensitivity, good stability, light weight, low noise, simple operation, the advantages of AC and DC. Particularly suitable for the measurement occasions without external power supply. PC-3A compact laser continuous respirable dust tester is in the introduction of imported most advanced laser technology, quickly and accurately measure the respirable dust particulate matter (PM2.5 \ PM10) of high-performance instruments. This instrument has a test fast, accurate and stable, simple operation, easy maintenance, no noise pollution, AC and DC characteristics. It applies to the CDC, health surveillance, environmental monitoring and other departments in real time. Third, the application areas of general workshops, public places, centers for disease control, health surveillance, environmental monitoring and other departments IV Features PC-3A other products, compared with an upgraded version of the instrument has the following salient features: 1, Detection PM2.5 and PM10, realizing the true meaning of one machine; 2, large-screen LCD Chinese display, display rich content, LCD with blue backlight; 3, has a built-in real time clock with the time measurement data storage, user-friendly Statistics and analysis; 4, measuring data transmission through the serial port to the computer; 5, micro-printer, you can print your data without external power supply; 6, can store up to 2000 sets of data. V. measuring principle: The instrument according to China's health industry standards: "public places, the air of respirable particulate matter (PM2.5 \ PM10) measurement method light scattering method" (WS / T 206-2001) design. The instrument is assembled together by the sensors and data processor. Sensor is a key component of the data collection instrument, the principle of the part, the laser beam through a set of aspherical fine measuring a light beam into a uniform power density distribution in the side of the front beam trajectory is a front focus falls on the beam On the track, the focus falls on a photoelectric converter after scattered light collecting lens group, when a sampling air flowing through the laser beam and the scattered light is collected by the intersection of front focus lens group, airborne dust particles emitted its physical size corresponding to the scattered light, scattered light was collected through an optical lens, a focal point after receiving by the photoelectric conversion element and converted into corresponding electrical signals. Sample gas inlet sensor located in the instrument's top position. Collection of air power source is a brushless DC fan. After the electrical sensor data processor will be collected through electronic cutter large particles separated off by microprocessor humidity, mass concentration conversion. The results displayed by the LED display, store or print.
