  • Page 13: Overview

    1. OVERVIEW The compact type gas analyzer with built-in pump and filter is intended for heat treat furnace, plant cultiva- tion, and research-purpose chemical analysis. With the gas extractor, either simplified measurement probe (non-fixed type) or continuous measurement probe (fixed type) is selectable at option. Since a high-sensitiv- ity single-beam mass flow controller is adopted for the infrared sensor, long-term stability and maintainabil- ity are excellent.
