Zirconia O2 Sensors
Probe Series - Short Housing
The Probe Range of zirconium dioxide oxygen sensors are available in three lengths. Suitable for aggressive and polluted applications such as boiler exhausts. Longer probes are an ideal solution for thicker walled, insulated flue pipes.
FEATURES
* Zirconium dioxide (ZrO2) sensing elements
* Long life, non-depleting technology
* Integral heating element
* High accuracy
* Requires an external interface board to operate
BENEFITS
* No reference gas required
* No need for temperature stabilisation
* Compact enclosure

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.
