AMETEK Process Instruments has been the leader in tail gas analysis for over 40 years-with more than 1,100 installed 880 NSL analyzers and more than 100 million hours of run time. The 888, the successor of the 880 NSL uses field-proven and highly reliable UV technology to accurately monitor the H2S and SO2concentrations in sulfur recovery tail gas. This compact, rugged analyzer mounts directly on the process pipe, eliminating the complexity and safety issues of fiber optic coupled photometers.
40多年来,阿美特克过程仪器一直是尾气分析的领导者 - 安装了超过1,100台880台NSL分析仪,运行时间超过1亿小时。 880 NSL的后续产品888,采用经过现场验证的高可靠性UV技术,可精确监测硫磺回收尾气中的H2S和SO2浓度。 这款结构紧凑,坚固耐用的分析仪直接安装在过程管道上,消除了光纤耦合光度计的复杂性和安全性问题。
The 888 is the evolution of a well proven formula. All the best elements of the iconic 880 NSL are still there; Four year lamp life, no shelter required and steam blow back for ammonia salts. Building on this success the 888 offers improvements in a number of key areas.
888是经过充分验证的配方的演变, 标志性880 NSL的所有最佳元素仍然存在; 灯泡寿命四年,无需遮阳棚,蒸汽将氨盐吹回管道。 在此成功的基础上,888在许多关键领域提供了改进。
