Brief introduction: The instrument can be widely used in industrial pollution area, residential area, background station and other places of environmental air quality monitoring, enterprise factory, workshop or heavy metal pollution of TSP, PM10 and PM2.5 in the lead, mercury, chromium, arsenic, cadmium and other heavy metal pollutant monitoring, meet for heavy metals in atmospheric pollution source component inspection measure, emissions monitoring, the demand of the total amount control, to improve the air quality evaluation system has important significance. Features: 1. At the same time monitoring of lead, mercury, chromium, cadmium, arsenic, copper and so on more than 20 kinds of element content; Detection limit of ng/m3 level; 2. Optional TSP, PM10 and PM2.5 particles or cutter, to realize the distribution of heavy metal particles on the kinetics of different diameter measurement. 3. The host USES the standard 19 "case, can be combined with conventional air station, mobile monitoring and so on comprehensive monitoring system of ambient air quality 4. Nondestructive testing, samples can be saved, in addition to the membrane filter, without other reagents or consumables; 5. Electrical design, lightning protection industrial instruments reliable, stable operation, instrument USES the radiation protection processing, no radiation measurement, with intelligent automatic alarm and fault diagnosis. 6. Has the RS232/485, USB, GPRS, ADSL, Ethernet data transmission, a variety of ways, accord with environmental protection on-line automatic monitoring data transfer standard, but also for users to customize extension custom functions. Technical indicators Applicable standards: the us EPA IO - 3.3 standard method, the X-ray fluorescence spectrum method to detect heavy metals in the environment particles" Monitoring elements: Pb (lead), Cd (Cd), Hg (mercury), As (arsenic), Cr (Cr), Cu (copper) and so on more than 20 kinds of heavy metal elements; Measuring range: 0 ~ 100 mu g/m3 The linear correlation coefficient > 0.99 Detection limit: ng/m3 level 2 hours (sampling time, velocity of 16.7 L/min) The standard samples with repeatability RSD < 1.5% (Pb) Accuracy: the relative error < 15% (Pb, contrast with national standard laboratory methods, sampling time is more than 1 hour) Sampling flow rate: 0 ~ 20 l/min (adjustable) Work style: continuous automatic monitoring Communication interface, RS232, RS485, GPRS, Ethernet Membrane filter cycle: 3 months (day 8 samples) Ambient temperature: (- 10 ~ 50 ℃ Environmental humidity: (0% ~ 90% RH) (no lon) Feet inches: 1800 x 600 x 800 mm (HxWxD) (the host) Weight: about 60 kg (monitoring system) Power source: 220 V AC (1 + / - 10%), (50 + 1) Hz, 600 W
