Features
- Non-stepped continuous measurement.
- Reduced loss of volatiles by the dynamic heating system.
- Long-term unattended operation.
- Low detection limit, high accuracy and resolution.
- Improved user interface and iPort communications software.
- Certified according to EN14907:2005 (PM2.5) and EN12341:1998 (PM10), and equivalence methods test: 2010, EN15267-1:2009, EN15267-2:2009.
- Equivalent monitor for PM2.5 according to US EPA EQPM-0609-183 and US EPA approved for PM10 (EQPM1102-150).
- A known volume of air is ducted through a size-selective inlet, which can be configured to measure PM10, PM2.5, PM1 or TSP and deposited on a self-advancing belt filter. The combined measurement of mass and volume of air are used to obtain the mass concentration reading.
- The 5014i model uses Carbon-14, as a source of Beta radiation, continuously measuring the mass concentration for PM10, PM2.5, PM1 or TSP fractions, through the use of Beta attenuation technology.
- The sample air volume is precisely controlled by means of a subsonic orifice.
- The Model 5014i advances the particle-laden filter sample according to user-defined parameters, such as mass accumulation limits, time intervals or flow rate range in relation to pressure changes.
- The filter belt will advance in a continuous pattern, as compared to stepwise measurement, resulting in the mitigation of particle losses. Additionally, the filter belt will advance if the sample exceeds the maximum load criteria.
- The Dynamic Heating System (DHS) allows the user to maintain the sample temperature as a fixed value or below a relative humidity threshold. The result is a system that heats only when necessary, eliminating the effects of humidity and ensuring that volatile aerosols remain intact for accurate measurement.
- Other advantages:
- Continuous recording of sample results during 60 minutes of each hour.
- Quarterly calibration. Other equipment requires a 10-minute calibration every hour, which results in a significant loss of data.
- 1 roll of filter tape (17 meters) every 6 months (2 rolls/year).
- Automatic zero.
- Ethernet connectivity for efficient remote access
- Improved user interface including one-button programming and large display
- Flash memory for easy data storage and user software download.
- Improved electronic design optimizes the common design of the products
- Improved component layout for easy access to components
