CAPS PMex Monitor (Particle Optical Extinction)

Currently, there is a choice of 5 different wavelengths – blue (450 nm), green (530 nm), red (630 nm), far red (660 nm ) and near infrared (780 nm, at additional cost) – which match the spectral bands of most other particle optical properties measurement equipment. These instruments have a 1 second time response and provide a level of detection (3σ) less than 2 Mm-1 with 1 second integration time. These monitors are entirely self-contained, requiring no consumables such as zero air and can be operated autonomously for over 12 months using on-board data storage if one second averaging is chosen.
