ozone gas sensor
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.
-In-line or at-line
-Dissolved and gaseous applications
-Semiconductor, power-steam industries
-Pharmaceutical and chemical industries
Features and Benefits
Detection limits < 0.1 PPB (dissolved) or 0 mbar (v/v) gaseous
Low maintenance costs:
• Interchangeable anode/electrode: can be changed in few minutes at low cost
• Minimal membrane surface in contact with the sample reduces maintenance frequency
• 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.
