Rapidox 1100-OPT-MAX Oxygen Analyser
Product Information
The Rapidox 1100-OPT-MAX uses two cutting-edge optical gas sensors working in tandem to deliver the world’s first truly full-scale optical oxygen gas analyser.
This compact instrument can measure oxygen levels from as low as 0.1 ppm up to 100%, offering exceptional performance in speed, accuracy, stability and sensor longevity.

The Rapidox 1100-OPT-MAX is ideal for challenging applications such as measuring ppm levels of oxygen in hydrogen, helium and flammable gases, as well as high levels of oxygen in concentrators, incubators and glove boxes.
The high and low range oxygen sensors switch over automatically using a hysteresis function to optimise readings, with the switching point adjustable by the user.
Optical oxygen sensors are virtually drift free and factory calibrated for life, meaning the lifetime cost of ownership is more economical compared with other sensor types.
These sensors are ideal for demanding high oxygen applications where VOCs, flammable gases, CO, H₂ or He are present in the gas sample.
The optical oxygen sensor technology is based on luminescence quenching of a sensor dye. The dye is excited with red light, and the properties of the resulting luminescence are measured in the near infrared.
The presence of molecular oxygen in the gas quenches the luminescence, changing its intensity and producing a calibrated oxygen measurement.
This principle is very robust, shows virtually no interference from other gases and has a very low drift.
It does not deplete over time, unlike galvanic oxygen sensors with their limited shelf life, as the optics and electronics are hermetically sealed from the measured gas.
For typical indoor environmental conditions, a 5–10 year operating life is expected.
