New, highly selective ethylene (C2H4) sensor

MEMBRAPOR have launched a new, highly selective Ethylene (C2H4) sensor. This improved Ethylene sensor reduces the effect of background gases such as carbon monoxide (CO) and alcohols which is, as an example, vital in fruit ripening processes. Both gases together result in false C2H4 readings and would require additional sensor units to correct it. The diagram shows the improved selectivity of the A-type compared to the conventional C2H4/C-10 sensor when exposed to 100 ppm of carbon monoxide. It can be seen that there is a significant reduction of the cross-sensitivity, which is about 4 times lower than before. The new C2H4/CA-10 enables the reliable monitoring of ethylene. Together with Membrapor’s highly sensitive CO/CF-200 CO sensor and will therefore protect plants and people in the greenhouse.
