Detection limits < 0.1 PPB (dissolved) or 0 mbar (v/v) gaseous

Low maintenance costs:

  1. Interchangeable anode/electrode: can be changed in few minutes at low cost

  2. Minimal membrane surface in contact with the sample reduces maintenance frequency

  3. Large anode surface: the anode is less quickly consumed by the electrochemical reaction and must thus be changed less frequently

Easy calibration process (only 1 point needed): an Eeprom stores the calibration parameters and avoids recalibration process if the sensor is connected to another Dextens instrument

Temperature sensor is integrated in the cathode assembly, enabling a faster temperature reading

Protection cap with special surface treatment: the sensor is very hygienic

Stainless steel construction: ideal for harsh chemical conditions and high pressures

The Dextens ozone sensors are ideal for high-precision measurements under harsh conditions. The measurement range varies from trace to saturation level (0.1 ppb to 400 ppm). Its concept and precise mechanical assembly ensure an optimal performance, a life cycle of about 8 years and low maintenance costs.

This Ozone sensor is based on a Clark Cell and consists of a semi-permeable membrane, gold and silver electrodes immersed in an electrolytic solution. It has the same design and uses the same technology as the oxygen sensor, the main difference being that the gard ring is in platinum instead of silver.
