Combination Probe KS1D

Simultaneous measurement of the concentration of O2
and oxidising gas constituents (CO/H2)
- Heated, electro-chemical measuring cell, made of zirconium dioxide ceramic (ZrO2)
- Use of proven measuring principles
- Simultaneous measuring of oxygen O2 and detection of oxidisable (combustible) parts of flue gas
- Display as COequivalent (COe)
- Cost-efficient measuring for monitoring and optimisation of oil- and gas combustions
Range of measuring O2: | 0…18%Vol. O2 – with limitations 0…21 Vol.% O2 |
Preciseness of measuring: | O2: +-5% of measuring value – not better than +- 0,3 Vol.% |
Response time t60: | O2 <= 10 seconds |
Failure impact: | Change of temperature of measuring gas in dependency of preciseness of temperature control of ZrO2 measuring cell |
Cross-sensitivity: | against SO2, NH3, NO, Propan, other arenes |
