Limiting current type sensor oxygen sensors
When voltage is applied to a zirconia electrolyte cell, oxygen is pumped through the zirconia disc from the cathode side to the anode side because the carriers of the current flowing through the zirconia electrolyte are oxygen ions. By attaching a cap with a pinhole on the cathode side of the cell and by increasing the voltage over the cell the current shows saturation due to the rate limiting step in the transfer of oxygen to the cathode. This saturation current is called limiting current and is nearly proportional to the ambient oxygen concentration.
Below the advantages of the oxygen sensor:
Measuring range 1.00 to 96.0 vol.% oxygen
High accuracy
For many types a more or less linear characteristic
Small temperature dependence of the sensor signal
Low interference with other gases
Long service life
In many cases â??single point calibrationâ?? necessary only once
Applications:
Medical
Laboratory
Food industry
Household/gastronomy
Measuring technique
Security technology/monitoring
(electrical-) industry

LED light.
For the Mosquito killer Led Bulb Light, is a 900 lumen bulb that doubles as an insect killer. The light features a blue UV LED which attracts insects into a Mosquito Killer grid.And the Mosquito Killer grid uses only 1W of electricity, while the light itself uses a meager 9W – and both can be used independently.They are used at home and outdoor. A brush is provided to clean off insects once the bulb switched-off.Compare to other traditional mosquito killer, this bulb has no chemicals, no sprays and hence no fumes to our life. • 2nd generation 2-in-1 LED LIGHT Bulb Plus LED Mosquito Killer Bulb • Wattage: 10W • Blue UV light • Lumen: 900-1000lm • Color Temperature (CCT): 6500K • Input Voltage: AC 90-130V & 220v-240V • With CE and ROHS Operation: Step1: Switch it on,both lighting +killing are on. Step2: Switch on again,light off,only killing on. Step3: Switch on again,killing off,only light on. Step4: Switch off, both off.
