Tianlan Optoelectronics
TLG-1000
Dilution CEMS
A coordinated sampling, dilution and analysis system for low-concentration industrial emissions.
- Measures
- SO₂ · NOₓ · CO₂
- Principle
- Probe dilution with gas-specific analysis
- Manufacturer
- Tianlan Optoelectronics
Dilution at the sampling point
TLG-1000 dilutes a small stack-gas sample at the probe before gas analysis. The measurement chain brings the sampling probe, dilution control, gas-specific analysers and data acquisition together.
- Controlled dilution reduces the moisture loading presented to the analysis system.
- The supplied brochure describes a small critical-orifice sample flow and controlled dilution gas.
- Calibration gas can enter at the probe to assess the complete measurement path.
Analysis and integration
The supplied system material combines Tianlan sampling and dilution equipment with gas-specific analysis, including Thermo Scientific 43i and 42i configurations. Third-party instruments retain their manufacturer identity.
Agree the concentration basis, moisture and oxygen correction, calibration method and site data interface as one system specification.
