美国斯伽德公司为汽车，工业，潜水，医疗和安全监测市场提供了先进技术和产品。目前美国斯伽德公司研发生产了一款手持式分析仪采用专门的气体传感器，电池操作，易于使用。
美国斯伽德公司结合工程师和营销集团研发出几款气体分析仪，质量好，体积小，易操作，就如同掌上电脑一般。这些气体分析仪分别可测量氧（0至100%），一氧化碳（0 - 100 ppm），氦（0 - 100%），氢（0至100%）和一个组合，分析气体二氧化碳和氧气，二氧化碳可以测量到百万分之100%。所有的气体分析仪的单位，除为二氧化碳氧气，重量不到7盎司和较大的仪器也低于7英镑并且包括可充电电池。

除了气体分析仪，美国斯伽德公司还研发了一系列电化学气体传感器，传感器包括氧，氮氧化物传感器，一氧化碳传感器和氦传感器对于大多数应用程序利用领域中的汽车检测，工业应用，潜水，医疗和安全监控。


C-Squared, Inc. develops Advanced Technology for the Automotive, Industrial, Diving, Medical and Safety Monitoring Markets.

Currently there is a great need for specialized gas sensors and gas analyzers designed to be hand held, battery operated, and easy to use. In addition the analyzers must be rugged and accurate.

C-Squared has combined the resources of their Engineers and Marketing group to release several gas analyzers to the Market that demonstrate both quality, ease of use and performance in a case smaller than a PDA. These gas analyzers are for Oxygen (0 to 100%), CO (0 to 100ppm), Helium (0 to 100%), Hydrogen (0 to 100%) and a combination that will analyze gases for Carbon Dioxide and Oxygen where the Carbon dioxide can be measured from ppm to 100%. All the gas analyzer units, except for the CO2-O2, weigh less than 7 ounces and the larger unit is less than 7 pounds including the rechargeable battery.

In addition to the gas analyzers, C-Squared has a full line of galvanic gas sensors, including oxygen sensors, Nox sensors, carbon monoxide sensors and helium sensors for most applications utilized in the fields of automotive testing, industrial applications, diving, medical and safety monitoring.
