this infrared gas analyzer measures the concentration of gas by utilizing the characteristic of gas (molecule consist- ing 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, interference- compensating detector, etc. this analyzer is to be built in sampling equipment and optimally usable for measuring the concentrations of various gases. features 1. most suited for incorporation in equipment this analyzer can be readily built in customer? sampling equipment, because its analyzing block, signal process- ing 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 high- sensitivity 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 coex- isting 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. specifications power supply: 100v-240v ac, 50/60hz power supply voltage variation in running time; within 10%. power consumption: 130va max ambient temperature: -5 to +45 c ambient humidity: 95% rh or less enclosure temperature: -20 to +60 c enclosure humidity: 95% rh or less casing: zinc plated steel (special chromate) (jis: secc-c equivalent) steel color indoor-use dimensions (h w d): on table-top 176 433 229 mm mass (weight): approx. 9 kg warm-up time: about 4 hours (after power on) materials of gas-contacting parts: sample cell: sus304, chloroprene rubber infrared-ray transmitting window: caf 2 or sapphire internal tubing: fluoride ethylene resin data sheet zrc6 ndir type infrared gas analyzer 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 co 2 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 ex- posed to direct sunlight or the radiation from a high temperature object. avoid vi- bration, and select a clean place free from corrosive and/or combustible gas- ses. if installing outdoors, provide a suit- able casing or cover to protect the ana- lyzer from wind, rain, etc. standard requirements for measuring gases: temperature: 0 to 50 c moisture: below a level where satu- ration occurs at 2 c (con- densation unallowable). dust: 0.3 m or less (recom- mended membrane filter; zbbm6) pressure: 10kpa or less (flow rate: 0.5l/min)(gas outlet side should be open to the at- mospheric air) standard control for sample gas: calibration gas: dry gas interfere control gas: 2 c saturation measuring system: infrared-ray absorption method, non-dis- persion, differential flow system, single light source, double-beam system. date EDS3-126A apr. 1, 2011
