data sheet zrh this ndir gas analyzer is used for measuring co 2 , co, so 2 and ch 4 and features a high accuracy, multiple functions and easy operation through use of a microprocessor. it is housed in an easy-to-use horizontal case (can be flush mounted on panel, mounted on 19 inch rack, placed on table top), or vertical case (can be flush mounted on panel, mounted on wall). the analyzer provides a performance superior to the con- ventional double-beam system, is easy to maintain, and offers an excellent long-term stability. it is thus optimum for con- tinuous measurement in the combustion control of various industrial furnaces, in research on garden-plants, and so on. 1. the use of a microprocessor provides high accuracy, multiple functions and easy operation. zero and span calibration is accurate and easy just by pressing the calibrating keys. a self-diagnosis function is included. an automatic calibrating function can be provided as an option. range can be changed over by a external signal as an option. 2. an improved optical system provides long term stabil- ity, and there is a minimum of drift caused by contami- nation of the measuring cell, so the long-term stability is excellent. 3. adopting a serial dual-layer type of transmission detec- tor minimizes remarkable the interface from other gas components. 4. easy maintenance. the single-beam photometric system uses a sample cell only and eliminates the necessity of delicate adjustment for optical balance. the instrument is designed as a unit of simple construction featuring easy maintenance and checks. measurable gas components: single-component co 2 co, so 2 , ch 4 dual-component co 2 /co: landfill garbage application co 2 : 0 to 50% ch 4 : 0 to 80% measuring range: refer to measurable range combination table (page 5). measuring system: non-dispersion infrared-ray absorption method, deviation method, single light source ?single beam output signal: output 1; 0 to 1v dc output 2; 4 to 20ma dc (optional allow- able load resistance 550 ? or less). repeatability: 1st range (low range) within 0.5% of full scale 2nd range (high range) within 1% of full scale linearity: 2% of full scale zero drift: within 2% of full scale/week span drift: within 2% of full scale/week response time: within 15 seconds max.
