The ODOT sensor with an
integrated temperature sensor is based on optical measure: a diode
emitting blue light is directed to an oxygen light-sensitive layer.
The sensitive material reacts emitting a red light (luminescence)
which emission depends on oxygen concentration
This innovative method
assures reliable, precise and driftless measures, calibration is no
longer necessary. Without consumable, calibration and maintenance,
the ODOT sensor leads to a rapid return on investment. Only the
DOdisk is to be changed once every two years.
Oxygen-free consumption, the ODOT sensor is adapted to any fields,
including those with very low water circulation.
The PONSEL sensor can
be connected to any types of transmitters, display units,
controllers or data loggers with Modbus RS-485 or SDI-12 inputs.
Thanks to the sensor indexation, over 200 sensors can be connected
on a data logger.
Disruption-resistant: Integrated preamplification and digital
treatment of signals.
The optical sensor saves its calibration data for a better measures
All data concerning
calibration, history, users and measures are directly treated within
ODOT sensor and transmitted via RS-485 or SDI-12.
Compact, robust and light, the stainless steel
sensor allows a handheld or fixed unit application.
