Optical oxygen transducer for permanent measurements in salt water

HIGHLIGHTS:

• Two 4 ... 20 mA (or 0 ... 5 V) outputs: concentration and saturation
• Full pressure and temperature compensated
• Calibration in many applications only 1 time per year!
• No flow required

GENERAL:

The oxygen transmitter GODOX 200 is a robust measuring system for low-maintenance continuous operation. Compared to electrochemical sensors, it does not need any electrolyte. Measurement is done with a fluorescence transit time method. Together with the complete data processing, including automatic ambient pressure and temperature compensation, it represents a carefree package for continuous measurements. Measurement at depths of up to 30 m is possible. The lifetime of the replaceable measuring diaphragm is usually 2 years.
