The evolution of electronics influences virtually every aspect of our personal and business lives. The world of gas analysis is no exception as the premium placed yields and product quality increase. Often overlooked is the fact that the sensor is the heart of any gas analyzer. Analytical Industries Inc. focuses on optimizing the critical characteristics of the sensor for specific application and has produced the first real advancements in sensor technology in decades.

Designed and manufactured entirely in-house under a quality assurance system independently certified to ISO 9001:2000, MDD 93/42/EEC, EN12598-ISO 7767, ISO 13485:2003 standards for industrial, medical, diving, automotive and personnel safety applications, Analytical Industries Inc. offers the widest range of oxygen sensors and analyzers available today.

Advanced Galvanic Oxygen Sensor 0-1% Range
Most applications for percentage range oxygen analysis emphasize the need for longer life in order to minimize service requirements. But, the grey area transitioning from high ppm to low percent oxygen analysis presents the challenge of providing the best life, performance and price. Our unique ability to offer a number of solutions enables users to select the best option, see below, for their particular application.

Stability: < 1% of FS range at constant conditions

Advanced Galvanic % Oxygen Sensor
Reliability, extended long life and performance are critical to meeting the need for oxygen measurements imposed by today’s industrial process, medical, diving, natural gas and welding applications. In addition, XLT sensors, required when carbon dioxide concentrations exceed 0.5%, do not freeze and are capable of measuring ppm oxygen in 0-100% carbon dioxide gas streams.

• Accuracy: +1% FS under constant conditions
• Sensitivity: 0.5% of full scale range
• Low range: 0-10 ppm full scale
• Expected operating life: 24 months
• Response time 90% of full scale: < 10 seconds
• Recovery: To 0.1% (1000 ppm) from exposure to air < 30 seconds
• Expected life: 32-120 months in normal applications

Advanced Galvanic Oxygen Purity Sensor

The growing demand for a more cost effective method of qualifying medical grade (99.5%) and elevated (80-100% pure) concentrations of oxygen resulted in the
