Product Description
EI-133 Fine Particulate Sampler is a specific type of air sampling device designed to collect fine particles, often referred to as PM2.5 (particulate matter with an aerodynamic diameter less than 2.5 micrometers). The flow rate of the sampler is critical for accurate measurements. The flow rate of the sampler is critical for accurate measurements. It is often set to ensure a specific volume of air is sampled over a defined period. It is often set to ensure a specific volume of air is sampled over a defined period. EI-133 Fine Particulate Sampler plays a crucial role in monitoring air quality in urban areas, industrial sites, and other locations where fine particles can pose health risks.

FAQs of EI-133 Fine Particulate Sampler:
Q: How does the EI-133 Fine Particulate Sampler operate for air quality monitoring?
A: The EI-133 uses gravimetric sampling technology with standardized 47 mm filter paper to collect particulate matter (PM2.5 and PM10). It draws ambient air through the filters using a high-flow rotary vane vacuum pump, with automatic constant flow control ensuring consistent sample collection for up to 24 hours.
Q: What accessories and calibration tools are included with the EI-133 sampler?
A: The sampler comes complete with filter papers and a flow calibration kit, enabling immediate setup and accurate performance verification. These tools facilitate both initial installation and routine maintenance, enhancing operational reliability.
Q: Where can the EI-133 sampler be used and what are its key applications?
A: This sampler is designed for ambient air quality monitoring in environments such as urban areas, industrial sites, and research stations. Its weather-resistant, powder-coated metal surface and broad operating temperature range make it particularly suitable for the varied Indian climate.
Q: What benefits does the automatic flow control offer to users?
A: Automatic constant flow control maintains sample integrity by ensuring a steady air flow rate (1.0 to 1.5 m/min), regardless of filter loading or environmental conditions. This results in more accurate and reproducible particle concentration measurements.
Q: How can users retrieve and manage sampling data from the EI-133?
A: Data can be transferred directly via USB or RS232 interfaces to external computers or storage devices. The clear digital display also allows real-time monitoring of sampling status and parameter settings, simplifying data handling and analysis.
Q: When should the filter paper be replaced during sampling operations?
A: The filter paper should ideally be replaced after each 24-hour sampling session, or sooner if high particulate loadings are expected. Regular replacement ensures accurate gravimetric readings and maintains the efficiency of particle collection.
