OLCT 20 固定式气体检测仪详细介绍：
OLC(T) 20系列气体检测仪用于户内外设施监测及其他相关应用，以合理的价格满足您的气体检测需求。
OLC 20 检测器
新一代OLC 20 可燃气体传感器具有抗毒化功能。该设备反应时间极快且性能可靠。并有M25或3/4" NPT螺距的机壳可选。
OLC 20D 检测器
OLC 20D检测器基于OLC 20传感器设备，配有15米长电缆（标准版）及安装压盖，用于与数据记录器的直联。高温版可在200°C环境下运行。
新一代产品：新优势
不锈钢检测器可防止腐蚀剂对设备造成损坏。分类为IP 66，防尘、防水渗。转动设备头部即可断开OLCT 20 及 OLCT 20D预校准传感器。“智能”传感器可在危险区域外的工作台上进行校准。
