IN-SITU
ZIRCONIA OXYGEN ANALYZER < ZIRCOMAT-C >
DATA SHEET
This oxygen analyzer is used to continuously measure
oxygen concentration in combustion exhaust gas of industrial
boilers or furnaces, and is ideally suited for combustion monitoring and control.
The detector (ZFK) used with the analyzer is directly
inserted into the objects measured, eliminating the need for a
sampling device and provides quick response.
The converter (ZRY) features 3 measuring ranges, one
touch calibration and NEMA4 housing.
Comparing to the current converter (ZRM) , this ZRY is
recognized as economical type with simple functions.
ZFK, ZRY
General-use detector
FEATURES
1. Sampling device is unnecessary
Gas sampling devices such as a gas aspirator, a dehumidifier, etc. are unnecessary because of use of directinsertion type detector.
2. High speed response
The adoption of a flow guide tube utilizing the flow of the
measured gas assures quick response (less than 7sec).
3. Dust-tight and water-proof housing
Aluminum die casting housing of converter satisfies
NEMA4 and IP65 standard.
4. 3-measuring ranges and one touch calibration
The converter has 0-5, 10, 25 vol% 3 ranges easily
changed by pin connection and zero and span are simply
calibrated by key operation.

CAUTIONS
• If combustible gas (CO, H2 etc.) exists in the measured
gas, error will occur due to burning at the sensor section.
The inclusion of corrosive gas (Si vapor, alkaline metal, P,
Pb etc.) will shorten the life of the sensor.
• When the measured gas temperature is high (+300°C or
higher), the flange should be separated from the furnace
wall in order to bring the detector flange surface
temperature below the specified value +125°C). The flow
guide should be attached in the direction in which the gas
flow to the detector decreases.
• When dust more than 1g/Nm 3 is included in the gas,
manual blow down is necessary.
