Use the sensor to take measurements in a stream or pond. Remote
logging is required when using the sensor in the field since the
wireless signal cannot be transmitted under water.
Note:
Note: The Metal Guard accessory (PS-3604) is required when
taking field measurements to protect the sensor cap. The accessory
includes a rope that attaches to the eye hook on the protective
cover.

The Wireless Optical Dissolved Oxygen Sensor was specifically
designed to be used in water. However, reasonably good qualitative
results may be obtained in air.
Oxygen gas concentration in air is calculated by taking the DO
2
Saturation value from the sensor and multiplying it by 20.9%. This is
the assumed partial pressure contribution of O
2
in air. Best accuracy
will be achieved in high humidity environments. Long term
measurements in dry air are not recommended as this will dry out
the probe sensor cap.
Note:
Note: The probe should not be used in an environment with
flammable, caustic, or corrosive gases.
Follow the same instructions as using the sensor in water, except
select O
