Features
No cross interference; specific gas can only absorb laser light at specific wavelength.
Unique optical design effectively eliminates the impact of vibration on absorption measurement.
Flexible measurement mode; can conduct in-situ measurement under 1000°C, or analyze and monitor gas in combination with bypass sampling system.
Light intensity compensation algorithm ensures instrument delivers accurate results under condition of excessive dust and particulate matter.
Multiple analysis modes, including direct absorption, 1F, 2F.
In combination with professional spectrum analysis method, guarantees sensitivity of measurement results and linearity range.
Temperature and pressure compensation with internal or external temperature and pressure sensor, in combination with optimized algorithm, improves measurement accuracy.
Distributive micro-processing technology is specially designed for fast analysis with response time ≤1s.
