Technical Specifications
The Combination Probe KS1D-Ex is designed for measuring oxygen (O2) and unburnt residues (CO/H2) in flue gases. It operates effectively at temperatures up to 450 °C (842 °F). The probe is available in two immersion depths: 500 mm (19.7 in.) and 860 mm (33.8 in.).

Measurement Characteristics
- Oxygen (O2) Range: 0 to 18 Vol. %, with a restriction up to 21 Vol. %
- COe Range: 0 to 10,000 ppm
- Accuracy: O2: ±5% of measured value, COe: ±25% of measured value
- Response Time: O2 ≤ 20 s, CO ≤ 10 s

Technical Data
- Internal Resistance: 15 to 30 Ω for both O2 and CO/H2 electrodes
- Output Voltage: O2-electrode: 150 mV to -30 mV, CO/H2-electrode: -30 to 800 mV
