Portable Dissolved Ozone Analyzer OXYTRANS TR Transmitter Version

The Principle

OXYTRANS continuously measures the content of oxygen in liquids and gases. Designed for applications that require maximum sensitivity and high accuracy, this device is used in various industries all around the world. Breweries and soft drink manufacturers determine the O2 content in deaerated water and beverages with OXYTRANS. Oxygen measurement during fermentation is an ideal application. Numerous power plants use the sensor to monitor oxygen levels in their boiler water. The state of the art optical measurement technology is based on the effect of luminescence quenching, i.e. the radiationless redistribution of excitation energy via a molecular interaction. An indicator layer on a small glass component (“optical window”) installed in the measuring head is illuminated with blue-green-light. When the indicator molecules absorb the incident light they are promoted to a higher energy state. After a certain time they convert back to their ground state during which a detectable red light is emitted. If O2 is present the energy is transferred from the indicator molecules to the oxygen. The detected signal decreases according to the oxygen content. OXYTRANS displays various units, e.g. ppb, ppm and % oxygen. The lightweight portable device is very robust and can easily be connected with hoses.
