Electronic catalyzing device

An electronic catalytic converter relating to microcosmic scientific research equipment, which comprises a catalytic bed (1), a heat-variable light (2), a cooling light (3) a three-way adjuster (4), a power supply AB with 200V (5), a thermosensitive resistor (6), and a cold resistor (7) while the circuit is sequentially connected, which is characterized in that a thermosensitive resistor and a cold resistor are set under and beside the catalytic bed (1) to finish catalyzing via the three-way adjuster. As the thermosensitive resistor (6) is controlled according to the through the instructions of the heat-variable light and the three-way adjuster (4) is set closely to the heat-variable light and the cooling light, the adjustment should be flexible according to situations. The invention is mainly used in that the liquid specimen is put on the catalytic bed (1), and the three-way adjuster (4) is turned to the heat-variable light (2) being turned on .Only seconds later, the picture of microorganisms can be found in rapid change. This is only the summary and the enthusiasts may find out the details themselves.
