INZ-TN2ZRE-E
1. oVERViEW
This infrared gas analyzer (type: ZRE) has been tested to the requirements of UL 61010-1/CSA-C22.2
No.61010-1, second edition, including Amendment 1, or a later version of the same standard incorporat-
ing the same level of testing requirements.
This instrument measures the concentration of NO, SO
2
, CO
2
, CO and CH
4
contained in sampling gas on
the principle that different atomic molecules have an absorption spectrum in the wave band of infrared
rays, and the intensity of absorption is determined by the Lambert-Beer law.
Since this instrument incorporates a compact O
2
sensor, it allows measuring up to 5 components simulta-
neously by using the built-in O
2
sensor (up to 4 components if O
2
sensor is excluded).
Furthermore, use of a microprocessor and large sized liquid crystal display realizes improvement of oper-
ability, accuracy and multi-functions.
This instrument is optimum for measuring combustible gas exhausted from boilers or incinerators, and it
is effective for steel gas analysis [blast furnace, steel converter, thermal treatment furnace, sintering (Pellet
equipment), coke furnace], storage and maturity of vegetable and fruit, biochemistry (microbe), [fermen-
tation], air pollution [incinerator, exhaust gas desulfurization, denitration], automotive emission (excluding
tester), protection against disasters [detection of explosive gas and toxic gas, combustion gas analysis of
new building material], growth of plants, chemical analysis [petroleum refinery plant, petroleum chem-
istry plant, gas generation plant], environment [landing concentration, tunnel concentration, parking lot,
building management] and various physical and chemical experiments.
