NDIR TYPE INFRARED GAS ANALYZER DATA SHEET This infrared gas analyzer measures the concentration of gas by utilizing the characteristic of gas (molecule consisting of different-kind atoms) that it absorbs the infrared ray of a specific wavelength. Stable and accurate measurement is ensured due to use of a mass flow sensor with a high sensitivity, interferencecompensating detector, etc. This analyzer is to be built in sampling equipment and optimally usable for measuring the concentrations of various gases. ZRC6 FEATURES 1. Most suited for incorporation in equipment This analyzer can be readily built in customer’s sampling equipment, because its analyzing block, signal processing circuit and power unit are all accommodated in a compact case. 2. High measurement accuracy and stability A single light source/double beam system, and a highsensitivity mass flow sensor ensure accurate and stable measurement. 3. Minimum influence by other gases An interference-compensating detector substantially suppresses interference by the disturbing gases coexisting in sample gas. 4. Wide dynamic range A range ratio of max. 1:20 can be secured in standard 2 ranges. Range selection follows the external selection input signal. Gas inlet, outlet, purge gas inlet size: Rc1/4, or NPT1/4 female screw Purge gad flow rate: 1L/min± 0.5L/min Purging is required when combustible and corrosive gases are contained in the atmosphere or the range of CO2 is less than 100ppm. In other cases, purging should be made as necessary. Scope of delivery: Analyzer × 1, power fuse × 2, Instruction manual × 1 Mounting method: On table-top Installation condition: Install the analyzer at a place not exposed to direct sunlight or the radiation from a high temperature object. Avoid vibration, and select a clean place free from corrosive and/or combustible gasses. If installing outdoors, provide a suitable casing or cover to protect the analyzer from wind, rain, etc. Standard Requirements for measuring gases: Temperature: 0 to 50°C Moisture: Below a level where saturation occurs at 2°C (condensation unallowable). Dust: 0.3 µ m or less (Recommended membrane filter; ZBBM6) Pressure: 10kPa or less (Flow rate: 0.5L/min)(Gas outlet side should be open to the atmospheric air) Standard control for sample gas: Calibration gas: Dry gas Interfere control gas: 2°C saturation Measuring system: Infrared-ray absorption method, non-dispersion, differential flow system, single light source, double-beam system.
