  • Why Buy From Delta Pro Meters & Measurement

    The Extech EX623 clamp meter - 5 tools in one!  

    The versatile Extech EX623 5-in-1 clamp meter was specifically designed for plant, HVAC/R, and electrical professionals in commercial, institutional, and industrial settings.  No other clamp meter offers the convenience and versatility of five meters in one tool, enabling technicians to get more while spending less.

    * A robust 400A AC/DC amp clamp meter offers current load readings quickly on AC systems as well as DC systems like industrial DC motors, automotive, heavy equipment, and marine applications. An advanced, True RMS Multimeter offers comprehensive functions for extensive troubleshooting and True RMS accuracy for measuring signals distorted by motor drives, motor controls, power supplies, and other electronic systems.

    * An exclusive built-in infrared thermometer is ideal for quickly identifying overheating motors or locating hot spots on electrical panels, or HVAC vents without contact.

    * A non-contact voltage detector allows you to quickly and conveniently check for voltage prior to attaching the multimeter’s test leads to the device under test.

    * A dual-input Type-K thermometer lets you get readings from two sources and calculate Delta-T with a push of a button.

    * DMM functions include AC/DC Voltage & Current (including DC µA), Resistance, Capacitance, Frequency, Duty Cycle, and Diode/Continuity, 40,000 count display.

    FEATURES

    Extech’s 5-in-1 clamp meter is a smart tool and a smart buy for maintenance professionals. For troubleshooting both new installations and preventive/ongoing maintenance and repairs, the EX623 accurately measures AC and DC current, voltage, and temperatures.

    The EX623’s infrared thermometer and laser pointer make point-and-shoot temperature readings simpler and safer.  And, having two Type K thermocouple inputs makes differential temperature (delta-T) calculations like superheat and sub-cooling measurements easier to perform.

    For furnace and boiler maintenance flame rod current measurements, the DC microamp function is a handy surprise. The EX623’s generous 32mm jaw opening handles large conductors.

    The EX623 makes users’ everyday installation, diagnostic, and maintenance tasks simpler and easier – and with less toolbelt/toolbox clutter.

    Man overwhelmed by choice of multimeters

     

    Confused?

    Overwhelmed?

    It’s one thing to know what basic functions you require of a multimeter - Voltage, Current, Resistance, Capacitance, Temperature etc.  It’s another thing to nut through all the specifications and understand exactly what your multimeter is capable of.

    A lot of the time you only need to know the course parameters of each measurement,  e.g. up to 1000A current,  600V voltage,  1 mega-ohm resistance etc.  But sometimes, particularly in industrial applications, you need to know how your multimeter performs a particular test, how accurate the displayed results are, and whether or not the multimeter will be safe and reliable for the intended application. 

    This is where terms such as count, range, resolution, basic accuracy, IP rating, CAT rating, True RMS, crest factor and others come into play. 

    If you are not familiar with these terms and how they relate to multimeter measurement, Steve has put together a series of blogs to explain in laymen’s terms what each mean.
