More Information
Summary:The utility model relates to an atmospheric ion meter, comprising a parallel plate type ion collector, a micro-current amplifier, a mainboard, a liquid crystal display, a miniature printer, a polarizing power supply, a battery cell without maintenance and a charging circuit. The charge collected by the parallel plate type ion collector is amplified by the micro-current amplifier and is input to the analog-to-digital converting circuit of the mainboard. An analog signal is converted into a digital signal. The digital signal is processed by a mainboard circuit and at last drives the liquid crystal display and the miniature printer. The utility model is high in measuring precision, wide in range of application, convenient in operation, advanced in technique and good in performance and is suitable for the field operation in particular.
