AC Milliammeter, Model J0414, is suitable for the laboratories of middle schools and polytechnic schools to measure current intensity in the AC circuit.

J0414型交流毫安表适用于中学、中专等实验室测量交流电路中的电流强度。

To realize the high efficiency of dernisting, thenew type cathode wires and anode tubes with superperformance were developed for increasing the current density and field intensity.

实现除雾高效化，关键在于研制高性能的新型阴极线和阳极管，提高电流密度和电场强度。
