Applications: outdoor and indoor air quality control in a wide dynamic range, from atmospheric background to health – hazardous levels. Continuous atmospheric monitoring, special dedicated experiments (e.g. dynamic flux chambers), semi-automatic analysis of liquids.
Features:
- Principle of operation: Cold Vapor Atomic Absorption Spectroscopy (CVAAS);
- Complies to the standard EN 15852. No need carrier gas;
- LCD TFT 5″ color touchscreen enables a handy interface for parameters setup, measurements programming and results display;
- The results are displayed onscreen analyzer in the form of time-series absolute (pg), time series concentration (ng/m3), and UV light absorption peaks;
- Full process data including UV light absorption peaks is stored internally, whereas a total of 3,200,000 measurements can be recorded by internal logger.
- Three basic modes of operation are programmable: regular (ambient air sampling), calibration with standard additions and calibration against zero-air (including zero-air supply). The two latter modes are available when the accessory, the mercury dosing device GA-7300 is connected.
- Extremely flexible programming of measurements, from just „press START and measure“ to measurements and calibrations at fixed periodicity (from each 5 minutes to each hour) and alternatively, with a dedicated daily schedule (individual measurement at a selected time of the day and with the selected detailed parameters).
- Switching inlet channels via external PTFE valves (optional).
- Full control of the analyzer and dose device is accomplished and data is downloaded through Ethernet and Wi-Fi. The analyzer itself forms a Wi-fi station, one can connect to it via PC or smartphone, no need to install any software. The analyzer continues its operation autonomously in case the connection to your PC is lost or terminated. The analyzer automatically restarts in the case of power failure.
- Information for data logging systems is provided through the Ethernet port (Modbus TCP) and via RS-485 port (Modbus RTU).
- The basic feeding voltage of the equipment is 12 VDC. Adapter for mains 110/220 VAC 50/60 Hz is included.
- Replaceable aerosol particle filter is installed within the analyzer.
- Version for 19“ rack is available.
- Analyzer complies to EN15852 standard. Carrier gas is not required.
