Extech Instruments EX623 Clamp-on Multimeter - 400 AC/DCA, 600 AC/DCV, Freq, Res, Cap, Temp True-RMS + NCV & IR-Thermometer


The Extech EX600 series are dual-input clamp-on multimeters which will measure AC Current, AC or DC Voltage, Resistance, Frequency, Capacitance, and Temperature. The EX600 series can also function as a non-contact voltage detector with a LED alert.The EX600 series also come with many of the standard Extech features which makes these meters suitable for a wide range of applications. These features include things such as Data Hold and Peak Hold, Autoranging with manual override and Auto Power Off with an audible alert. The EX600 series also features a 1.4" (36mm) jaw opening to fit conductors up to 500MCM and is built with a double-molded housing for increased protection.Unique to the EX623 is the ability to also measure DC Current. The EX613 will measure up to 400 AC or DC Amps. The EX623 also features the built-in Infrared Thermometer for non-contact temperature measurements.
