this ndir gas analyzer features high accuracy, multiple functions and easy operation through use of a microproces- sor. it also utilizes a mass flow detector noted for its high sensitivity and reliability. this analyzer is used not only for measuring environmen- tal pollution but is also used for various processes and/or experiments. this product, combined with sampling system (zsp), has passed the type-approval test based on weight and mea- sure act. (1) use of a microprocessor provides high accuracy, mul- tiple functions and easy operation. ? maximum of 3 gas components can be calibrated with the built-in automatic calibrator (option). using a signal from a zirconiz o 2 sensor (zfk3) or from any other o 2 sensor, the gas analyzer is able to out- put a value converted into o 2 (option). alarm function to emit high/low limit contact output is also available (option). measuring range can be selected by using external single (option). zero and span can be calibrated with high accuracy, simply by pressing calibration keys. ? self-diagnosis function is included. (2) this analyzer utilizes mass flow detector featuring high sensitivity and reliability. it has 2 standard measuring ranges with a range ratio of up to 1:20. (3) three different gas components can be measured si- multaneously by connecting a zirconia o 2 sensor (zfk3), in addition to one-and two-component type sensors. (4) besides the standard measurement type, a sample swi- tching type and a differential flow type are also available. general items power supply: 100v 10% ac, 50/60hz 115, 220v ac also available on request note: refer to "code symbols" power consumption: 125va max. ambient temperature: ? to +45 c ambient humidity: 90% rh or less enclosure: steel casing, indoor-use dimensions (h x w x d): 835 x 220 x 232 mm mass{weight}: approx. 24kg finish color: munsell 2.5y 8.4/1.2 indication: 4-digit led for concentration 4-digit led for sub-indication output hold: output hold prior to manual/auto calibra- tion is possible. hold on/off is select- able. standard requirements for sample gas: temperature 0 to 50 c (dehumidification 2 c satu- ration or less) dust 0.3 m or less pressure 9.8kpa{0.1kgf/cm 2 } or less (flow rate 0.5 r /min) standard control for sample gas: calibration gas dry gas interfere control gas 2 c saturation warm-up time: about 8 hours (after power on) about 4 hours for sample switching type material of gas-contacting parts: sample cell; 304 stainless steel, neoprene rubber infrared-ray transmitting window; caf 2 or sapphire internal tubing; teflon tube, silicone tube, toaron tube gas inlet/outlet, purge gas inlet size: rc 1/4 (pt 1/4 internal thread) or npt1/4 internal thread features specifications data sheet zrg ndir type infrared gas analyzer date EDS3-110D jun. 29, 2005

5 description of sample switching system the measured gas is divided into two, and in one of the flow paths, a high performance converter is provided to con- vert carbon monoxide into carbonic acid gas. here, the carbon monoxide in the measured gas is eliminated and the gas is led into one cell of the high-sensitivity infrared ana- lyzer. in the other flow path, the gas is led directly into the other cell of the analyzer. these flow paths are changed over via changeover valves sv 1 and sv 2 every 50 seconds by means of the changeover valve drive signal transmitted from the analyzer. by carry- ing out this changeover cyclically, the output of the ana- lyzer varies with the concentration of the carbon monoxide in the measured gas. use of the obtained variation width as a measured value enables improving the s/n ratio and eliminating the effect of interfering components plus zero drift. infrared light source (single light source) motor rotary sector (one-point chopper) sector synchronous signal alarm output range identification signal calibration output sv drive signal remote range input external hold input (option) output, 0 to 1v or 4 to 20ma dc operating key sample gas inlet sample cell ac voltage amplifier sample gas outlet gain changeover a/d cpu relay drive signal indicator indication d/a contact input,output ram rom distribution cell (interference filter) interference compensating detector trimmer reference cell reference gas inlet reference gas outlet co measured gas 1ry filter pump sv 4 reference gas sv 3 sv 1 sv 2 sv 2 sv 1 t emperature controller co/co 2 converter flowrator 2ry filter zrg3 reference cell sample cell sample switching type analyzer relay output signal fundamental diagram (sample switching type)
