Product Short Description
Product Introduction
The GE Panametrics XDP‑221‑2 is a rugged, explosion‑proof local display and interface module designed exclusively for use with GE Panametrics thermal conductivity gas analyzers and transmitters. It provides real‑time, at‑a‑glance visualization of gas concentration measurements (e.g., % or ppm for O₂, H₂, or other process gases) in hazardous industrial environments. Built with microprocessor‑based electronics and an infrared, through‑the‑glass keypad, it enables safe local operation and configuration without opening the explosion‑proof enclosure. This module is certified for use in Class I, Division 1 hazardous areas, making it a critical component for process monitoring in oil & gas, petrochemical, and power generation facilities.
