SOLAREx681 is a cost-effective hydrogen flame ion (FID) monitoring instrument, when organic matter passes through the detector, there will be ions in the flame, under the action of polarization voltage, the current between the nozzle and the collector will increase, the current signal can be detected and recorded to obtain the corresponding LEL data. General organic compounds have a response on the FID, and the response time is less than 1 second. Generally, the larger the molecular weight, the higher the sensitivity, and the vast majority of organic matter has a good response on FID.

Analyzer design

The SOLAREx681 Flammability Analyzer is a highly integrated, in-line LEL measuring instrument with a heating monitoring chamber and a control unit that allows the analyzer to continuously measure the low explosion limit of exhaust gases in the 0-100% LEL range. SIGNAL SCIENTECH designs the LEL analyzer using an advanced and unique measurement principle that directly measures the combustible content of the sample to obtain LEL data, ensuring measurement accuracy and linearity.
