The CoGDEM Guide to Gas Detection

Leigh GreenhamHardback

Now available as an eBook fromAmazon>>

Industrial gas detectors form an important part of safety systems designed to protect users from the harmful effects of flammable, toxic or asphyxiant gases. These gases can cause explosions, damage health or deplete the oxygen content of the air. Consequently, accurate gas detection is vital for protecting human life as well as process plant and the environment.

This practical guide has been written by CoGDEM (the Council of Gas Detection and Environmental Monitoring) to assist users or specifiers of gas detection equipment. The book begins with a quick reference for selecting a gas detection system, which outlines the most salient points. There is more detail on this topic as well as on a variety of other areas such as gas detection requirements and training, sensor technologies, and instrument calibration and maintenance. There is also information on the science of gases and lists of relevant reference documents. The book covers UK, EU and global regulations and standards.

The chapters are written by key experts, providing comprehensive information for novice and experienced industry professionals in the gas detection field.

Author Biography

Leigh Greenham是一名注册工程师，他的职业生涯专注于电子仪器仪表。他毕业于拉夫堡大学(Loughborough University)，获得电气和电子工程学位，由肯特仪器(Kent Instruments)赞助，现在是ABB的一部分。他早期的职业生涯涉及过程工业的仪器设计，包括在日本的两年合同。
1990年，利进入工业气体检测领域，并被任命为克罗康检测仪器(Halma集团的一部分)的技术总监，在接下来的15年里担任该公司的技术总监。

Crowcon’s products cover most of the categories of gas detectors featured in this Guide, including personal, portable, transportable and fixed equipment using remote gas detectors as well as sampling systems. The sensing technologies used by Crowcon encompass most of those covered in Chapter 5 of this Guide.
Crowcon had been a founder member and strong supporter of CoGDEM since it was formed in the 1970s. Leigh’s involvement with CoGDEM began as soon as he joined Crowcon, becoming a member of several of the standards’ working groups and chairing the Industrial Sub-Group.
Leigh于2005年离开Crowcon，成立了Electromagnolia Ltd，这是一家从事仪器仪表项目工作的咨询公司，包括市场研究、产品认证、传感器选择、产品设计/管理和技术培训和演讲。“电玉兰”获委托负责“工业气体检测中心”的日常工作。除了检测工业气体外，“工业气体检测中心”还让利参与本港一氧化碳中毒的调查工作，包括与多个政府部门和贸易组织进行游说活动。
Throughout his career, Leigh has authored and co-authored many gas detection articles, which have been subsequently published in technical journals, and he has presented at global symposia. He has convened BSI standards working groups and is on the steering groups of several industry organisations.
