Features

Adopt UV-DOAS and PLS algorithm, low detection limit and small temperature drift.

NOX content can be directly obtained by measuring NO and NO2.

 without NO2→NO converter not interfered by particulate matter, moisture and other factors.

No optical moving parts, with high reliability, vibration has no effect on measurement.

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.
