EE80系列建立了暖通空調(diào)領(lǐng)域CO2測量的新標準。CO2，相對濕度和溫度測量的開關(guān)包含在同一個模塊中。
        EE80的基礎(chǔ)型號 - CO2和溫度測量一體式 - 通過安裝一個插拔式濕度測量模塊，就可便捷的實現(xiàn)功能擴展。
        CO2的測量采用紅外線工作原理，其的自動校準程序可對紅外源老化進行補償，從而保證了其的長期穩(wěn)定性。
        EE80提供模擬信號輸出。利用顯示器（選項）可以即時顯示實際測量的數(shù)據(jù)。
        另外增加了一個可調(diào)節(jié)開關(guān)點和開關(guān)滯后的開關(guān)輸出選項。
        多種模塊形式針對客戶的需要提供了解決方案。
