85DM-HZ二合一系列数显表有很多优势，高，小型，经济，一个小型按钮可以两值，所以相当于一个当两个用，节约空间和成本，它它通常代替85L17 指针式板表，它适用于发电机以及其它需要显示电压和频率的设备。

85DM-Hz series 2in1 Digital Meter has many advantages: high accuracy, miniature, cost-effective, a microswitch change to display double value, so one can use as two and save space and cost. It usually used to take place of 85L17 series panel meter, and suit togenerator and other device for displaying voltage & Hz, and so on.
