In the waste gas treatment systems of industries such as petroleum, chemical, and pharmaceutical, thermal storage incinerators (RTOs) play an important role in environmental protection and emission reduction. However, due to their high-temperature operating characteristics, they also face potential risks of combustion and explosion. Traditional detection methods often struggle to cope with transient fluctuations in exhaust gas concentration, while the LEL online monitoring instrument based on flame temperature detection (FTA) principle, with its unique technological advantages, has become an innovative solution to ensure the safe operation of RTO.

The FTA principle achieves direct and rapid identification of the lower explosive limit (LEL) concentration by accurately measuring the temperature characteristics of combustible gas combustion. Its response speed of less than 1 second is more than 5 times faster than traditional detection methods, and it can effectively capture dangerous signals of sudden spikes in exhaust gas concentration, striving for critical emergency response time for the system. This millisecond level warning capability shifts security management from passive response to proactive prevention.

SOLAREx seriesLEL concentration monitorIt is developed and produced by Higona, and its principle is to directly measure the concentration of combustible gases in the sample through hydrogen flame temperature detection (FTA). It can respond to all combustible gases (including H2S, CO, H2, etc.) with a response time of less than 1 second. SOLAREx can ensure that the analyzer continuously measures the low explosive limit of exhaust gas, with a measurement range of 0-100% LEL.
