PC-3A dust concentrations exceeding the dust alarm alarm alarm dust content

PC-3A dust alarm Overview: PC-3A Chi Xiong continuous laser dust tester (hereinafter referred to as pocket dust monitor) is mainly used in public places of airborne particles (PM10, or PM2.5) concentration, can also be used for clean environment measuring unit volume of air in the number of 0.5 and 5.0μm particle size of dust particles. Having a dust concentration and dust particle count testing capabilities, and with the ambient temperature and relative humidity testing device. Instrument has a small, portable, test speed, high sensitivity, good stability, light weight, simple operation, all Chinese fast real-time display, AC and DC characteristics. PC-3A dust alarm technical indicators: 1, dust measurement files do: PM10, or PM2.5 2, Dust measurement range: 0.001 ~ 10.0mg / m3 3, the detection sensitivity: 0.001mg / m3 4, repeatability error: ≤ ± 2% 5, dust particle measurement files do not: (0.5, 5.0) μm second gear selection display 6, air sampling flow: 2.L / min (0.1 ft 3 / min) 7, sampling time: 1 minute, 2 minutes ... 30 points; and manual at any time. Direct-reading dust concentration (mg / m3) 8, with a public place monitoring mode, monitoring mode atmospheric dust concentrations have exceeded the alarm setting function; concentration threshold can be set 9, data storage capacity: 1000 sets of data, you can always check printing 10 is connected with the computer: massive data storage, network transmission, remote monitoring, test results can be printed 11, the instrument has a programmable clock chip, the measurements provide accurate date and time information 12, automatic self-cleaning correction 13, the working environment : temperature (0-35 ℃); humidity RH (20-70)% 14, Power supply: 220V AC power supply; built-in high-capacity lithium battery, can be used continuously for more than 5 hours and 15, instrument configuration temperature and humidity sensors (optional) 16 volume: 170mm × 150 mm × 70 mm 17, Weight; about 750g PC-3A dust alarm basic configuration: 1, the host of a 2, a 3 data connection cables, a 4 power charger, CD-ROM 5, the alarm one
