Multimeter - Digital Multimeter RS-232 Interface(DMM 129A) Product ID: DMM 129A


A multimeter which is known as a volt, ohm meter or VOM is an electronic measuring instrument that combines several functions in one unit. A multimeter are usually be used in measurements of AC and DC voltage, AC and DC current, and resistance.

Tecpel provides you digital multimeter which are most widely used because of their accuracy, durability and extra features . Our compact, contemporary multimeter are ideal for use in your home, office or DIY applications .

A good multimeter can also be used to troubleshoot electrical problems in a wide array of industrial and household devices. For example, your wiring systems and motor controls are common problems that can be solved easily by multimeter.

Besides, there are some tips that you must pay attention to before using the multimeter. Such as never measure resistance in a circuit when power is applied and never apply more than the rated voltage between any input jack and earth ground.

No matter what your purpose, our multimeter are a quick, simple and effective way of getting information of electronic measuring .The quality multimeter of Tecpel can fit your needs.
