The Model 8872 is a Windows-based data logger, based on
Windows Professional. The 8872 includes a number of
hardware and software features to ensure that the device
matches the field reliability of the 8832, while offering the
convenience of a Windows-based platform and integration
with Agilaire’s AirVision software.
The core of the 8872 is a fanless PC, typically 4 GB of
RAM. The device is equipped with a 128 GB solid state
flash drive (SSD).

For all digital versions of the 8872, the remainder of the
enclosure simply provides convenient USB, serial, and
HOMI I/O connections in a standard 3U rack mount
enclosure, a form factor similar to the 8816 / 8832 family.
However, the 8872 also supports traditional analog /
discrete I/O via a variety of internal I/O modules and a
protection / connector board to provide familiar detachable
terminal block connections to the back. The layout of the
connections is designed to make the unit easy to use as a
‘drop in’ replacement for an 8816 or 8832.
