Gas Analyzer GA320 N2O CO2 CH4 Data Sheet

Product catalog summary

Overview: The Gas Analyzer GA 320 is designed for measuring up to six IR-active gases with high precision and low detection limits. It is suitable for applications in emissions monitoring, wastewater treatment plants, recycling, environmental monitoring, and inspections.

Key Features:

Direct display of measured values and user-friendly operation via a large touch panel with plain text menu navigation.
Precise measurement results even at low detection limits.
Integrated PC for fast data processing and analysis.
High long-term stability and low calibration effort due to patented NDIR measurement method with reference pressure measurement.
Open interface architecture for flexible data transmission, standard RS232.
Low service costs due to reduced maintenance requirements and high operational reliability.
