由中国矿业大学、兖州矿务局焦化厂振兴电子设备厂共同研制的 MQCO-Ⅱ型一氧化碳报警器,于近期通过了中国统配煤矿总公司综合利用局组织的技术鉴定。这种报警器采用了对一氧化碳气体具有高灵敏度的 MQCO 型半导体气敏元件作为检测传感器。当室内一氧化碳浓度达到300±50ppm 时,报警器及时发出声、光报警。在连续报警2min 内,报警器自动开启排气扇进行换气。该报警器通过特殊的供电方式,对气敏元件进行动态清洗,保证了整机具有较高的灵敏度和可靠性。为确保使用安全,在报警器内部设有定时自
The MQCO-Ⅱ carbon monoxide alarm jointly developed by China University of Mining and Technology, Yanzhou Mining Bureau Coking Plant Zhenxing Electronic Equipment Factory has recently passed the technical appraisal organized by the Bureau of Comprehensive Utilization of China General Coal Mine Corporation. This type of alarm uses an MQCO type semiconductor gas sensor which has high sensitivity to carbon monoxide gas as a detection sensor. When the indoor carbon monoxide concentration reached 300 ± 50ppm, the alarm promptly sound, light alarm. In continuous alarm 2min, the alarm automatically open the exhaust fan for ventilation. The alarm through a special power supply, dynamic cleaning of gas sensors to ensure the machine has a high sensitivity and reliability. In order to ensure the safety of use, there is a regular internal alarm
