Luminescence-based Optical Trace Oxygen Sensor Features:

• Operates in any oxygen concentration without damaging the sensor

• Highly selective and sensitive to oxygen

• Long life, non-depleting technology - no need to store in an inert gas environment

• Fast response and purge times

• Connects directly to a controller via RS485 interface

• Factory calibrated - User calibratable^a

• Low power - high accuracy

Luminescence-based Optical Trace Oxygen Sensor Benefits:

• Compact footprint, flow-through housing with sealed base

• Contains no hazardous materials; RoHS & REACH compliant

• Insensitive to pressure fluctuations

• Can be used in vacuum applications
