LASmini CH4, CO, CO2 & H2O
For monitoring: CH4, CO, CO2 & H2O
LASmini CH4, CO, CO2 & H2O Analyzer
The TRACE-GAS LASmini CH4, CO, CO2 & H2O-Analyzer combines reliability, precision, and ease of use in a compact device. Designed for low-calibration, direct hot-wet measurement of methane (CH4), carbon monoxide (CO), carbon dioxide (CO2), and water (H2O) using laser absorption spectroscopy (TDLAS) without the need for a sample gas cooler or complex gas conditioning.
- Measurement ranges for the gases:
– CH4 0-20.000 ppm
– CO 0-5%
– CO2 0-20%
– H2O 0-20% - Hot-wet measurement without a cooler – direct measurement in hot, humid exhaust gas at cell temperatures up to 190 °C
- Four gases simultaneously – all components in a single measurement cell, with no time delay
- No cross-sensitivities – high selectivity through measurement of individual absorption lines
- No condensation, no adsorption – thanks to a heated measurement cell and vacuum operation
- Wide dynamic range – up to 5 orders of magnitude from the detection limit to the end of the measurement range
- Easy integration – Modbus TCP/IP, 24 V DC power supply, compact design
- Virtually maintenance-free
- No consumables required
- Process monitoring
