This product is an industrial-grade carbon dioxide transmitter that uses microelectronics to measure CO2 concentration, reacts quickly and sensitively, and avoids the life and long-term drift problems of traditional electrochemical sensors. It is suitable for life science incubators, fermentation workshops, mushroom houses, refrigerated and fresh-keeping, gas-controlled庫, incubators, carbonization boxes and other occasions that require stable and accurate percentage-level CO2 measurement.
