Product Description:
SO-E2-250 Limiting Current Oxygen Sensor Zirconia Oxygen Sensor Can replace SO-B0-250
Features:
First, the limit current oxygen sensor SO-E2-250 working principle:
Because the carrier of the current in the zirconia electrolyte is oxygen ions, when a voltage is applied to the zirconia electrolyzer, oxygen is pumped through the zirconia disk to the anode. If... give
The cathode of the electrolytic cell is covered with a hole, and the rate of oxygen flow to the cathode is limited. Limited by this rate, it gradually increases with the applied voltage
Plus, the current in the cell will reach saturation. This saturation current is called the limiting current, and it is proportional to the oxygen concentration in the surrounding environment.
Second, the limit current oxygen sensor SO-E2-250 application:
Medical: Oxygen concentrator, incubator
Laboratory: inert gas treatment cabinet (glove operating box), bacterial incubator
Food industry: packaging, food inspection, monitoring of fruit ripening process (storage/transportation)
Home/Cooking: Automatic baking/baking (high temperature >100℃)
Measurement technology: Fixed/portable oxygen meter, measurement with controlled oxygen content, air conditioning and circulation
Safety technology/monitoring: fire protection (nitrogen increase, e.g., server room), greenhouse, wine cellar, gas storage, refinery, diving, fermentation unit
Electrical industry: inert gas processors and cabinets, inert gas welding monitoring, storage in the presence of increased nitrogen (anti-oxidation), drying equipment, nitrogen concentration
Instrument, exhaust gas measurement
Three, the limit current oxygen sensor SO-E2-250 advantages:
Wide measuring range, 10 ppm~96% oxygen
High precision
Many models have linear characteristics
The sensor signal has little dependence on temperature
Low cross sensitivity
Long service life
In most cases only one "single point calibration" is required
