Brief introduction: PC - 3 b continuous multifunction laser dust tester is used to measure inhalable dust in the air of public places (PM10 and PM2.5 and TSP) of dust concentration in the unit volume in the air and clean environment for particle size (0.3 ~ 10.0) mu m the number of dust particles, is the center for disease control and prevention, health supervision, environmental monitoring departments such as real time measurement of above project of a new generation of intelligent measuring instrument. This instrument adopts the advanced light scattering theory in semiconductor laser for measuring light, dust in the air for high sensitive non-contact measurement. Managed by single chip microprocessor and control the whole test process, using high resolution large high brightness LCD screen, the real time display in Chinese. Instrument is also equipped with environment temperature and relative humidity test device, and dust concentration test and dust particle counting function. The instrument is small in size, easy to carry, has the test speed, high sensitivity, good stability, light weight, simple operation, the advantages of ac/dc, suitable occasion measurement, no power supply can be widely used in all kinds of public place and electronic, optical, food, aerospace and aviation, etc. Technical indicators: Dust measuring gear don't: PM10, PM2.5 and TSP; Dust measuring range: 0.001 ~ 10.0 mg/m after, in the TSP mode maximum range greater than 10 mg/m after; The detection sensitivity: 0.001 mg/m after, repeatability error: plus or minus 2% or less; Dust particle measurement file don't: (0.3, 0.5, 0.7, 1.0, 2.5, 5.0) including m six shows at the same time; Air sampling flow: 2.83 L/min (0.1 to 3 f t/min), humidity automatic correction; Sampling time: 1 points, 2 points... 30 points and manual at any time, direct reading dust mass concentration (mg/m3); Data storage capacity: 500 groups of data, can query to print at any time; With computer: realize the huge amounts of data storage, network transmission, remote monitoring, can print test results; Working conditions: temperature (0 to 35 ℃), humidity RH (20-70) %. Working power supply: 220 v ac power; Built-in high capacity lithium battery, can use more than 5 hours continuously; Instrument configuration of temperature and humidity sensor (optional); Size: 170 mm * 150 mm * 150 mm; Weight: 750 g.
