Product details
Product FeaturesConsultation Hotline:
| The integrated collaborative measurement of air particulate matter mass concentration and heavy metal concentration can analyze the distribution pattern of components in air particulate matter; |
| Equipped with multiple particle cutters for users to choose from, it can measure the distribution of heavy metal particles on different dynamic diameters; |
| Measurement of the content of 30 heavy metals including lead, cadmium, chromium, arsenic, etc., with detection sensitivity on the order of pg/m3 and expandable element types; |
| The host adopts a standard 19 "chassis, which can be installed on both mobile monitoring vehicles and standard cabinets of air automatic stations; |
| 20 years of XRF technology accumulation, lightning protection industrial grade electronic and electrical design, the instrument has high operational reliability and stability, 24-hour/365 day fault free operation, and also has intelligent fault diagnosis and self elimination functions; |
| ※ Non peak light path design, built-in multi level filters, automatic switching for low background measurement; |
| ※ Built in calibration module, XRF spectrum horizontal and vertical coordinates are automatically calibrated simultaneously, calibration frequency can be set arbitrarily, and specific metal internal standard source is also built-in, which can achieve automatic quality control and alarm; |
| Stable control of the sampled operating flow rate can be achieved through a mass flow controller and temperature/pressure sensors, while also enabling automatic flow calibration; |
| Equipped with RS232/485 USB、GPRS、ADSL、 Multiple data transmission methods such as Ethernet can achieve remote transmission, monitoring, and verification of operating parameters, status, and data; |
| The system software adopts advanced layered modular design, with powerful and flexible functions such as data setting, calibration, saving, display, query, analysis, and transmission. The data complies with the "Data Transmission Standard for Pollution Source Online Automatic Monitoring (Monitoring) System" (HJ/T 212-2005). At the same time, users can quickly and conveniently customize and expand any other custom functions; |
| Professional multiple processing ensures that the instrument has no radiation leakage during measurement. |
