SLE-FPS105-1

SLE-FPS105-1, PM2.5 Ambient Air Sampler has been designed in accordance with the requirements specified in 40 CFR Part 50, Appendix L. It consists of a sample air inlet, downtube, particle size separator (impactor), filter holder assembly, air pump and flow rate control system, flow rate measurement device, ambient and filter temperature monitoring system, barometric pressure measurement system, timer, outdoor environmental enclosure, and suitable mechanical, electrical, or electronic control capability to meet or exceed the design and functional performance

FEATURES:-
Fully automated control

• The fully automatic model is computer based model.
It contains software which is easy to handle and clear visualization of data, graph and data table.
• No manual calculation is required for sampling information.
• User friendly Software.
• Measures both filter as well as ambient temperature.
• Also monitors operational parameters such as barometric pressure & flow rate digitally.
• Automatic control of sample volumetric flow rate and other operational parameters.
• Provides data information at the end of each sample period in file format.
• Determines the elapsed sample collection time for each PM2.5
• Automatic leak check of the system.

Flow control regulation

The flow control of SLE FPS 105 is strictly maintained at 16.67 LPM as per USEPA standards. It can also be regulated subjected to the customer's requirement.

Data interface through LCD

The data which is collected during the process is displayed in real time on LCD screen which works as an interface between user and computer.

Clock timer system

The sample time required for the analysis of sample can be fed into the system and the system will automatically stop after the specified time.

Collection efficiency

The collection efficiency of SLE FPS 105 is greater than 99.7% as measured by the DOP test ( ASTM D 2986-91) with 0.3 particles at the sampler's operating face velocity.

The report shall contain the following information:- • Sample ID
• Sampling location
• Start time and Date
• Stop time and date
• Total Elapsed time
• Flow rate (minimum, Maximum and average)
• % CV in flow data
• Barometric Pressure (Minimum, Maximum and Average)
• Ambient Temperature (Minimum, Maximum and Average)
• Filter Temperature (Minimum, Maximum and Average)
• Sample volume (m3)
• Error messages and Flags
• All the data should be retrievable through RS 232 and or USB .


The sampler displays the following fields on the Main screen:

1 Control Panel
2 Data Table

This feature allows the user to browse for a file that is, to search any file from the stored database. The required data can also be saved in Excel to plot graph of the available parameters.

3 Data Graph

This helps the user to see the graphical interpretation of the readings.

4 Settings & Info

This feature allows the user to caliberate the flow pulse (Pulse/L) periodically

Interactive control panel
The SLE-FPS 105-1 is equipped with an interactive control panel which helps to specify the flow rate, filter's initial weight, sample time. It also alerts filter saturation level when it is choked.
Fully automated control
The SLE FPS 105-1 is a fully automated system loaded with a computer interface for automatic control and data generation.
Collection efficiency
The collection efficiency of SLE-FPS 105-1 is greater than 99.7% as measured by the DOP test ( ASTM D 2986-91) with 0.3 particles at the sampler's operating face velocity.
Data safety
The data collected during the process is saved into the system which is backed by a UPS for automatic shutdown and start of the system which results in Datastorage and accurate sampling results.
Automatic report generation
The Data collected by SLE FPS 105-1 automatically generates a report for a specified sample time. This report contains information such as

1 Volumetric flow rate
2 Filter temperature
3 Relative humidity(%)
4 DP
5 Barometric pressure
6 Elapsed sample time
User login system
The SLE FPS 105-1 is a sampler which is password protected so as to minimize data theft and bring greater efficiency in the process.
Clock timer system
The sample time required for the analysis of sample can be fed into the system and the system will automatically stop after the specified time.
Data interface through LCD
The data which is collected during the process is displayed in real time
