A high-performance, portable, field-deployable gas analyzer

Project description

Portable Gas Sensor Module: A Field-Deployable O₂, CO, and CO₂ Analyzer Networked with WIZ750SR and PoE Summary Developed by UL Research Institutes’ Fire Safety Research Institute, this open-hardware gas analyzer uses three WIZ750SR serial-to-Ethernet modules to network high-fidelity O₂, CO, and CO₂ sensors through a single external PoE cable. Overview Large-scale fire experiments may require gas-concentration measurements at several locations inside or around a structure. Conventional high-accuracy paramagnetic and NDIR analyzers are often rack-mounted, requiring long sampling tubes between…
