Use ACCURRA-Zr, ACCURRA-S 2030. Kiln oxygen and CO guide fuel burn and flag combustion trouble. Dusty, hot gas; high-dust Zr probe or conditioned extractive sample.
The measurement and why it matters
Kiln oxygen and CO guide fuel burn and flag combustion trouble. This application matches the catalogue specification directly.
Oxygen and carbon monoxide in combustion gas show how well fuel is burning. Too much air wastes heat, too little leaves carbon monoxide and unburnt fuel. A continuous reading lets the operator or the control system trim the burner instead of guessing.
Combustion gas is hot, often dusty and sometimes wet. ACCURRA-Zr mounts on the duct and reads oxygen with no sample line, its sensor protected just outside the wall, with probe options for high dust and for temperatures up to 1400 C, while extractive ACCURRA-S analysers read CO and other gases from a conditioned sample.
Typical buyers in India: cement plants (JK Cement is an existing customer). Where this matches your plant, send us the gas, range, pressure and temperature at the tapping point and we will confirm the analyser and sample path.
Models and ranges
| Model | Measures | Range | Sensor and notes |
|---|---|---|---|
| 2030 | Carbon monoxide | Percent ranges | Confirm the range against the datasheet |
| ACCURRA-Zr | Oxygen in flue gas | Percent | Zirconia, in-situ, air calibration, auto blowback; high-dust and 1400 C options |
Process notes
What the analyser reads here
Gases of interest: O2, CO. Analyser fit: ACCURRA-Zr, ACCURRA-S 2030.
The table above lists each model with its range; where a row says to confirm the range, we check it against the datasheet for your application before quoting.
What to settle before ordering
Dusty, hot gas; high-dust Zr probe or conditioned extractive sample.
We would rather confirm these points at the start than discover them at commissioning, so please include them with your process details.

Sampling and installation
- Every ACCURRA-S has an internal fine filter and rotameter. Regulate sample pressure and flow externally; the catalogue recommends about 1 LPM and a sample pressure of 2 to 10 psig.
- Keep sample lines short, clean and dry, and vent the sample somewhere safe.
ACCURRA-S sample specification: non-corrosive, non-toxic, non-flammable, non-condensing and dry, free from entrained oil; sample pressure 2 to 10 psig, regulated externally; flow about 1 LPM; dust below 3 micron. Where your sample differs, we design conditioning around it.

What the data sheet asks for
Send what you have and we will ask for the rest.
- The gases to measure, the range, and the accuracy you need
- Background gases and their typical composition
- Sample temperature, pressure and dew point at the tapping point
- Dust level, and whether the gas carries tar, oil or condensable vapour
- Process connection and, for ducts, the duct diameter
- Where the sample vents to, and at what pressure
- Area classification of the tapping point and of the analyser location, and the IP protection needed
- Distance between the tapping point and the analyser
- Outputs you need: 4-20 mA, dual range, relays, Modbus RTU
- Calibration approach, calibration gas available, and whether blowback is required
- Utilities at site: power supply, instrument air, nitrogen, steam and cooling water, and the ambient temperature range
- Gases and ranges: O2, CO
- The point to confirm: Dusty, hot gas; high-dust Zr probe or conditioned extractive sample.
