Products Description
DW233
DW233 digital DC low resistance meter, also known as micro-ohmmeter, ohmmeter, equipotential tester, using microprocessor technology, four-wire test, safe, precise and reliable.Mainly used for measuring the conductor resistance of the cable, switch, socket, relay contact resistance, the resistance of the transformer winding coil, motor, shell and equipment, lightning protection zone, ground beam, structure, cabinet, steel bar, pipe, Windows, fence, radiator, assembly line connection between objects such as metal components resistance test.It is widely used in telecommunication, electric power, meteorology, machine room, oil field, electric power distribution line, tower transmission line, gas station, factory grounding grid, lightning rod and so on.
DW233 digital DC low resistance meter consists of host, monitoring software, test line, communication line, etc.Host large LCD display, clear at a glance, port overload protection function, avoid misoperation burnt instrument.Can store 500 groups of data, resistance measurement range: 0.001 m Ω Ω ~ 300.0 K.The upper computer software has the functions of reading, consulting, saving and reporting historical data.
