The GAS-PM2.5DT Series Air Sampling Systems are designed for remote unattended continuous air sampling applications. The GAS-PM2.5DT Series Air Samplers feature a brushless motor
with electronic motor speed control that maintains a user selectable flow rate. The flow rate range attainable through the filter media is dependent upon the air porosity of the filter media. The GASPM2.5DT Series design accommodates rapid field service and component replacement.
The electronic flow control measurement sub-system of the GAS-PM2.5DT Series provides an operator selectable standard flow measurement and a constant flow of air through the filter medium. The air velocity is measured by a precision-machined DP sensor. The controller can be set to a maximum sampling flow rate up to ~100 CFM (~170 m3/hr) depending on the filter paper air resistance and dimensions. The bright VFD readout displays multiple air sampling information including current flow rate, average flow rate, current temperature and totalized volume. The filter holder can be custom designed to accommodate any filter size and type. The GAS-PM2.5DT model utilizes an 8”×10” (20,3×25,4 cm) filter. Optional software is available to download air sampling data via an RS-232 port. The software provides a monitoring report, file creation and setup via a laptop computer.
