For paint shops, printers, dry cleaners, woodworkers, vehicle repair facilities, chemical production areas and wherever indoor air quality monitoring is required: the Eco Sensors® Model C-21 gas sensor helps you comply with the new VOC air quality regulations for hydrocarbon gases and solvent vapors.
对于油漆店、干洗店、木材车间、汽车修理厂、化工生产领域，室内空气质量的监测是非常必要的。Eco Sensors® Model C-21气体传感器用于监测VOC烃类和溶剂蒸发气体，符合相关空气质量监测法规。
美国ECO Sensor C-21 VOC挥发有机性气体传感器 Benefits优点:
- Constantly monitors your work environment. Detects leaks and poor air quality before they are a health hazard. Alarms below OSHA TLV for most common solvent-based VOCs. 不间断的监测您的工作场所环境。预防性的监测泄漏和空气质量变差，报警值低于OSHA TLV要求的VOCs浓度。
- No installation. Easily used and understood by non-technical personnel. 无需安装。即使非专业人员使用也简单易懂。
- Virtually no maintenance. 几乎免维护。
美国ECO Sensor C-21 VOC挥发有机性气体传感器 Features特点:
- Highly sensitive to solvent vapors and other VOCs. Bright green-yellow-red display clearly shows hazard level of gas or vapor. 对溶剂蒸汽和VOCs气体高度灵敏。高亮清晰的绿-黄-红显示有毒气体浓度。
- Detects down to OSHA, EPA, and other regulatory-mandated levels…typically at low ppm concentrations. 检测低于OSHA、EPA和其他监管规定水平。通常在低的ppm浓度。
- Has built-in rechargeable battery for portable use in tracking leaks. 内置可更换的电池，方便检测泄漏。
- Rugged construction with many safety features. 坚固的结构有许多安全功能。
