Sensing Foil Considerations:
We offer 3 different types of foils on our optodes. The Pst3 & FDO701 sensing foils are protected by an optical isolation layer, making the foil extra rugged and insensitive to direct sunlight. The fast response sensing foil is not equipped with this layer; ambient light intensity higher than 15000 lux may cause erroneous readings. We recommend the more rugged and stable FDO701 foil in applications where fast response is not needed.
*Only use 4330F if fast response Oxygen, and/or fast response temperature is needed. The standard sensing foil is protected by an optical isolation layer which makes the foil extra rugged and insensitive to direct sunlight. The fast response sensing foil is not equipped with this layer; ambient light intensity higher than 15000 lux may cause erroneous readings. To avoid potential bleaching the fast response foil shouldbe protected from ambient light when storing the sensor. We recommend the standard foil in applications where fast response time is not needed.
**Please note: All sensors use RS-232 for configuration.
