Specifications
The document outlines the specifications for a gas analysis system, including measurement methods, gas components, and protective measures. The system uses NDIR and paramagnetic methods for measuring gases like CO, CO2, CH4, and O2. It operates within a range of 0 to 100 vol% depending on the component.

Performance and Measurement Ranges
Performance metrics include repeatability, range ratio, and response time. The system offers a repeatability of ±0.5% to ±1.0% of full scale for zero and span. The response time (T90) is within 20 to 40 seconds. Measurement ranges vary by gas component, with specific ranges for CO, CO2, CH4, and others.

Sample Gas Conditions
The sample gas conditions require O2 levels of 21% or less, with no mist or dust. The system is designed to handle gas pressures from 196 to 690 kPa and flow rates of approximately 500 mL/min.

Materials and Calibration
Materials in contact with sample gas include SUS304, SUS316, FKM, and others. Calibration methods include manual and optional automatic correction.

Environmental Conditions
The system is designed for indoor use, with operational temperatures ranging from -5 to 40°C and humidity levels of 90% or less. It should be placed away from direct sunlight and large vibration sources.

Utility and Protective Measures
The system includes flameproof enclosures and pressurized apparatus for safety. It uses protective gases and has specific requirements for hazardous areas.

Digital Connection and Communication
Options for digital connection include RS-485 with Modbus-RTU protocol, supporting communication speeds from 1200 to 19200 bps.

System Configuration
The system configuration includes various analyzer units and protective gas control units, with options for contact input-output or communication input-output. It is designed for both hazardous and non-hazardous areas.
