IN-SITU ZIRCONIA OXYGEN ANALYZER < ZIRCOMAT-C >
DATA SHEET
ZFK, ZRY
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 moni-
toring 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.
General-use detector
FEATURES
1. Sampling device is unnecessary
Gas sampling devices such as a gas aspirator, a dehu-
midifier, etc. are unnecessary because of use of direct-
insertion 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.
