Non-Dispersive Infrared Gas Measurement book's cover

Recently  published by the International Frequency Sensor Association (IFSA) Publishing, Non-Dispersive Infrared Gas Measurement is the first book, which describes non-dispersive infrared (NDIR) gas sensors and measurements in its historical development. Based on this unique approach the readers will be able to clear understand the future ways in development of such devices, technologies and applications, and create a solid background for the future patents and investigations.


The book is organized by the following way. A foreword written by R. J. Bruce Warmack - a senior research scientist from the Oak Ridge National Laboratory (USA), is followed by five chapters, which contain new information about various aspects of NDIR gas measurement, sensors and applications in Demand Control Ventilation system and HVAC. The list of references at the end of book contains fundamental publications (some of them are dated by 19th century) and most important patents in the relevant area issued by the authors and others. The Non-Dispersive Infrared Gas Measurement is available in both formats: print (hardcover) and electronic (pdf) formats.


The authors - Jacob Y. Wong and Roy L. Anderson have great industrial, research and business experiences, and hold together more than 100 US and international patents on advanced NDIR gas sensors.


Providing sufficient background information (from general classification to principles of measurements and realizations) and details, the book Non-Dispersive Infrared Gas Measurement is an excellent resource for advanced level undergraduate and graduate students as well as researchers, instrumentation engineers, applied physicists, chemists, material scientists in gas, chemical, biological, and medical sensors to have a comprehensive understanding of the development of non-dispersive infrared gas sensors and the trends for the future investigation and development.


Form the Readers' Feedback:


"That's what I looking for... Jacob Wong is leader in NDIR sensor as I know".


"It is really a good book and I'll recommend it to University library".



From Reviews:


A "must read" Book on Gas Sensors.


Interested in gas sensors? A newly-published book, Non-Dispersive Infrared Gas Measurement, lists various gas measurement techniques and discusses fundamental aspects and cutting-edge progress in NDIR gas sensors in their historical development.


The need for improved sensor technology in residential, commercial, automotive, military and industrial sectors has driven a continuous interest in sensor developments. Published papers usually report the observation of sensing based upon a property change of some material when it interacts with a gas (termed “Interactive” in this book). The reproducibility of such a sensor depends upon the stability of the material, which is nearly always subject to degradation over time. Physical-based sensors, on the other hand, rely upon detecting a measurable change of some physical interaction of the gas with the sensor (termed “Non-Interactive” in this book). Most high-quality analytical instruments depend upon physical interactions. NDIR sensors fall into the category of physical based sensors, which are usually the most reliable over time, if properly engineered.
