Overview
The document outlines the specifications and features of the Skypost PM FG, an automatic outdoor station designed for continuous atmospheric particulate monitoring. It complies with the EN12341:2014 standard and is capable of sampling PM10, PM2.5, and PM1, as well as heavy metals and VOCs.

Main Applications and Characteristics
The Skypost PM FG is suitable for dust sampling using LVS PM10 and PM2.5 sampling heads. It features a sequential substitution system for filter membranes, allowing for continuous operation without interruption. The device is weatherproof and operates in temperatures ranging from -20°C to 50°C. It maintains sampled filter temperatures below 23°C even when external temperatures reach 50°C.

Technical Specifications
The station has a flow rate capacity of up to 50 l/min and includes an electronic flow rate controller. It is equipped with sensors for atmospheric pressure, pressure drop on the filter, ambient temperature, and dry gas meter temperature. The volumetric measurement is precise within ±2%.

FilterGuard Technology
FilterGuard is the cooling system designed to protect sampled filters from heat and condensation, maintaining optimal conditions as per EN12341:2014 requirements. It ensures homogeneous cooling without cool points.

Data Management
The Skypost PM FG features a data management system that allows for continuous data storage, alarm management, and data export via USB and Ethernet. It supports data export into Excel files.

Testing and Compliance
The device has been tested in a climate chamber by an ISO17025 certified lab, confirming its operational capabilities in extreme temperatures. The FilterGuard technology has also been independently tested to ensure compliance with temperature maintenance requirements.
