Single Channel Tricolor Absorption Photometer Model 9406
Description
The Single Channel Tricolor Absorption Photometer (STAP) allows you to perform aerosol light absorption measurements at three wavelengths on-board Unmanned Aerial Vehicles (UAVs) and other mobile platforms where high sensitivity and time resolution are critical. Capable of 1Hz measurements, the system is compact, light and uses minimal power. The STAP uses light transmission through two small filters to derive the light absorption coefficient, from which the black carbon mass concentration can be determined. The unit offers one of the best detection limits on the market (20 ng/m3 black carbon). Development of the STAP is built upon BRECHTEL’s years of experience with our traditional light absorption instrument (Model 2901 TAP). Deploy the 9406 in conjunction with our other portable instruments to get a more complete picture of the aerosol under study.

Software
Integrated firmware drives each ACCESS module from the inside – the built-in microprocessor and sensors are able to sense, control, and report on instrument performance. A serially-communicated stream of data provides real-time user access to operating parameters and measurement values. An on-board micro-SD card can be used to store data locally.
Add the Model 9400 Base Module option with the UAV Reader software to your ACCESS package to benefit from a graphical user interface (GUI) that allows you to easily interact with the instrument and view measurements on the screen of the mini-PC. Multiple ACCESS modules can be connected via a micro-USB hub to easily change the system configuration. The 9400 also allows each of the connected modules to be remotely controlled via a single RS232 connection.
The UAV Reader software automatically recognizes which instruments are attached to the Base Module and adjusts accordingly. It is provided to facilitate configuration and monitoring of the ACCESS instruments on the ground and during mobile sampling, but is not required to operate the unit.
