随着煤矿行业的逐渐扩大，气体检测仪的种类也越来越多，特别是便携式气体检测仪，它能够实现煤矿井下的长时间连续检测，实时反应现场气体浓度情况，并在浓度超限时及时报警，是煤矿生产最基本的安全保障。
便携式气体检测仪的生产商很多，从仪器材料到制造工艺，从工作原理、特性分析到测量技术，从检测对象到应用领域，都可以构成独立的产品标准，衍生出各个不同的生产品牌，但从根本上讲，一个实用的便携式气体检测仪都必须具有最基本的性能。

所谓便携式气体检测仪，就是携带方便，操作简单的气体检测仪，方便使用者随身携带，实时检测工作环境的安全情况。
2、稳定性
稳定性是指气体检测仪在使用一段时间后性能保持不变的能力，这也取决于零点漂移和量程漂移。零点漂移是指在没有待测气体时，检测数值的偏移。量程漂移是指仪器连续置于待测气体中时测量值的偏移。理想情况下，一个传感器在连续工作条件下，每年零点漂移小于10%。 6XV1850-2LN10 CABLE TP CORD 15/RJ45 10 M Siemens
