The FES642-Y70 is a Dual In- and Single Out- flux chamber station, powered by Teledyne. This station is designed to measure low-level fluxes in two separate chambers with a single calibrated instrument. It utilizes a precision MODBUS and USB communications for temperature and humidity control, as well as a software package for data analysis and logging. The FES642-Y70 is a multi-channel, digital, cloud-based system ideal for other environmental applications, including stack testing, supply line monitoring, or facility monitoring.
