Features
Adopt UV-DOAS and stoichiometric algorithm, detection limit can reach 1mg/m3.
Employ holographic grating for light splitting and diode array for detection to obtain continuous and complete absorption spectrum; high resolution, ensuring low detection limit, small temperature drift and fast response.
No condensation process, avoid condensate water absorbing SO2 and cause low measuring result; reflecting actual working condition.
Without heat tracing pipe, fast response and low cost.
Compared with extraction method, it owns advantages of high measuring accuracy & reliability, low investment costs, fast response time, etc.
Compared with in-situ method, it owns advantages of online calibration, small measuring value fluctuation, high reliability, easy maintenance, etc.
Application
Applied in exhaust emission monitoring and process control in coal-fired power plant, garbage power plant, cement plant, glass plant, lime factory, ceramics factory, sintering process, coke oven, desulfurization technology, denitration technology, etc.
