Oxygen, the fuel for these electrochemical transducers, reacts chemically at the sensing electrode to produce an electrical

current output proportional to the oxygen concentration in the gas phase. The sensor’s signal output is linear over all four

ranges and remains virtually constant over its useful life. The sensor requires no maintenance or electrolyte addition and is

easily and safely replaced at the end of its useful life.

Advanced Galvanic ppm Sensor Technology

The sensors function on the same principle and are specific for oxygen. They measure the partial pressure of oxygen from low

ppm to 1% levels in inert gases, gaseous hydrocarbons, helium, hydrogen, mixed gases, acid gas streams and ambient air.

Proprietary advancements in design and chemistry add significant advantages to an extremely versatile oxygen sensing

technology. Sensors for low ppm analysis recover from air to ppm levels in minutes, exhibit longer life, excellent compatibility

with CO

and acid gases (XLT series) and reliable quality giving them a significant advantage over the competition.

Advanced Galvanic Percent Sensor Technology

The sensors function on the same principle and are specific for oxygen. They measure the partial pressure of oxygen from low

percent levels (0.05%) to 100% levels in inert gases, gaseous hydrocarbons, helium, hydrogen, mixed gases, acid gas streams

and ambient air.

Proprietary advancements in design and chemistry add significant advantages to an extremely versatile oxygen sensing

technology. Extending the expected life of our new generation of percentage range sensors now range to five and ten years

with faster response times and greater stability. Another significant development involves the first galvanic oxygen sensor

capability of continuous oxygen purity measurements and expanding the operating temperature range from -40°C to 50°C,

excellent compatibility with CO

and acid gases (XLT series) and reliable quality giving them a significant advantage over the

competition.
