Accuracy is defined after minimum 3 weeks of continuous operation. However, some industrial applications do require maintenance. Please, contact SenseAir for further information Note 2: SO2 enriched environments are excluded. Note 3: Notice that absolute maximum rating is 14V, so that sensor can be used with 12V+-10% supply Note 4: Different options exist and can be customized depending on the application. Please, contact SenseAir for further information Note 5: During power up, OUT1 and OUT2 are defined to be low. Exact value depends on many factors including temperature. Note 6: For the buffered outputs OUT1 and OUT2 the maximum output voltage range equals power voltage input minus 0,5 V AirTest11AirTest K30 C02 Engine Page 3 of 3
