美国英思科 BM25 复合式气体检测仪
BM25 复合式气体检测仪详细介绍：
BM25 将固定系统区域监测器的优点整合到一种可轻松移动且具抗震性的仪器中，通过扩散或抽样监测一至五种气体。
该设备专为班组保护或区域监视而设计，非常适合在固定检测系统无法工作的区域进行周边监测、钻机检修及移动式工作或短期工作。
有17种可更换的“智能”传感功能供BM25选择，系统可轻松适应各类应用及行业。当BM25检测到某种危险水平的氧气、有毒或易燃气体时，安装于顶端的信号台会朝各方向发出闪烁而明亮的信号，同时发出强大的103dB报警声。
BM25可用做独立监测器或串接使用，使报警信号从一台设备传输至另一台设备。该仪器可在已检测出的大气危险周围创建安全周边区域，或在广泛区域内传输手动发出的紧急信号。
BM25采用标准配置，安装有高性能的镍氢电池，可持续运行170小时。若使用本质安全的点滴充电电源可在危险地带实现长期区域监测。标准配置还包括STEL、TWA读数及将近四个月的数据记录功能（针对五种气体配置）。

America intrinsic BM25 composite gas detector
BM25 composite gas detector in detail:
The advantages of BM25 fixation system area monitorintegrated into an instrument which can easily move andshock resistance, by diffusion or sampling monitoring one or five kinds of gas.
The device is designed for the team to protect or regionalmonitoring and design, very suitable for not working at a fixed detection system region surrounding monitoring,machine maintenance and mobile work or short-term work.
There are 17 can be replaced with "intelligent" sensing function for BM25 selection, system can be easilyadapted to various applications and industries. When BM25 detects a dangerous levels of oxygen, toxic or flammable gases, signal station installed on the top of thedirection toward the flashing bright signal, at the same time, a powerful 103dB alarm.
BM25 can be used as independent monitors orconnected in series, the alarm signal from one device toanother device. This instrument can create securitysurrounding region in the atmosphere around the riskhas been detected, or transmit an emergency signalManual issued in wide area.
BM25 uses a standard configuration, installation of nickel metal hydride battery with high performance, sustainable170 hours of operation. If the use of intrinsic safety oftrickle charging power supply can achieve long-termregional monitoring in the danger zone. Standard features also include data recording function of STEL,TWA readings and nearly four months (for the five kinds of gas allocation).
