NHVOC-12 型总烃甲烷和非甲烷总烃便携式监测仪适用于各种VOCs污染源中挥发性有机物现场即时检测。仪器配有伴热管，全程高温伴热，最高可达180℃,有效避免高沸点、高浓度样品损失。仪器采用催化氧化-FID技术进行样品中甲烷、总烃样品的分析检测，催化效率达到99%以上。在采样泵的作用下，采集到的样品分别送入到空管及催化氧化管中进行分离分析，被分离后的样品依次进入到氢火焰离子化检测器(FID)中进行检测。通过集成软件自动计算，得到甲烷、总烃及非甲烷总烃的定性定量分析数据。

产品特点

符合HJ1012-2018中的仪器技术要求，同时满足HJ38、HJ583等方法标准要求；
配有伴热管，全程高温伴热，最高可达180℃，有效避免高沸点、高浓度样品损失；
可配套检测控制APP，配合分析仪主机进行VOCs现场排查分析、定位建档、点位检测数据记录和仪器控制，提高现场检测效率；
内置聚合物锂离子可充电电池，无须外部电源，电池可以持续供电4小时以上；
全自动测量，自动测定总烃、甲烷和非甲烷总烃浓度。
