The TSI-8534 Handheld Laser Dust Detector can simultaneously measure the mass concentration distribution of 5 different particle sizes, corresponding to PM1, PM2.5, respirable dust (RSP), PM10 and total PM (<15μm). The new graphical user interface and color touch screen allow you to quickly set up. The display is clear and easy to read, and the screen shows mass concentration, graphical data and other statistical data in real time, and can also display the status of the instrument's filter, laser and flow.
Manual and programmable data logging capabilities make the DUSTTRAKTM DRX benchtop models ideal for unmanned monitoring. They feature USB (device and host) Ethernet and analog alarm outputs for easy remote access to real-time aerosol concentration data. Users can choose from environmental protection boxes for field use, wireless transceivers (2.4GHz or 920MHz) and solar panels.
