Optical oxygen sensor (external)

The optical DO Sensor measures the partial pressure of the dissolved oxygen in liquids and gases. It utilizes a measuring principle based on red light excitation and lifetime detection in near infrared using luminescent oxygen indicators. Oxygen measurement is generally temperature dependent. Therefore, the optical DO Sensor is equipped with a temperature sensor for the measured medium and built-in temperature compensation.
