Request Quote


The True RMS Clamp-On Meter Model 203 is safety rated at 600V CAT IV. It measures AC + DC volts and amps, frequency, continuity, resistance and can also perform diode checks. An Adapter mode allows external sensor inputs to be displayed. The Model 203 includes temperature measurement and is supplied with a K thermocouple probe. A Delta relative function allows new measurements to be compared to a reference value and a MIN/MAX function keeps track of these high and low values.
