Description
Introduction
eLAS-70 laser gas analyzer is using tunable diode laser absorption spectroscopy(TDLAS) technique can be measured NH3/HF/HCL/CO/H2O/O2/CH4 at low range . eLAS laser gas analyzer reliable measurement of high resolution, high precision, , which can satisfy the process analysis and environmental monitoring application requirements
Features
Extremely high selectivity to the target gas
Functional safety, continuous status reporting
Long lifetime (10+ years)
Fast response times
Low power consumption possible
Very low cost-of-ownership (no regular replacement and/or calibration)
Low cost of the gas sensor through excellent scaling costs of the components
Applications
Process control/explosion pre-warning monitoring
Environmental flue gas emission monitoring
Boiler combustion control
Air separation and gas production
Aerospace, electric power, electronics, biological technology and scientific research institutions
