Extech EX505 Heavy Duty Autoranging Digital MultimeterDescriptionHeavy Duty, Autoranging Digital MultimeterThe Extech EX505 was designed specifically for industrial, plant maintenance, MRO, electrical and other professionals who need a heavy-duty, feature-rich multimeter.Functional OverviewThe EX505 is a True RMS digital multimeter capable of taking numerous measurements, including capacitance, frequency (dual sensitivity for electrical and electronic applications), diode test and continuity. Other features include Data Hold and Relative Hold, and auto-ranging, which automatically adjusts the measurement range based on the detected source, such as electrical components and electronic equipment.True RMS CapableIt can be very difficult to make accurate current and voltage readings in industrial and commercial environments where electronic devices are present. Fluorescent lights, motor drives, computer power supplies, and other electronic components can distort the AC waveform, making it hard for averaging meters to get an accurate reading. The EX505 uses a more advanced True RMS calculation to compensate for this kind of distortion.Rugged & VersatileDesigned to withstand harsh environments and usage, the EX505’s rugged, double-molded housing is IP67-rated (waterproof and dustproof) as well as drop-tested to 6 feet. The large, illuminated LCD displays a 4-digit readout (to 4,000 counts). The meter features 0.5% accuracy and a CAT IV-600V safety rating, protecting users even on outdoor wiring.Marine-ReadyAs a waterproof tool, the EX505 has become a popular multimeter among marine technicians and boat mechanics who risk dropping the meter off a boat, pier or dock and into water. Since the meter is waterproof and floats, it’s easy to recover and is ready to resume work once retrieved. The EX505 features Auto Power Off (with disable) to conserve battery life, and the meter is backed by a three-year limited warranty.In The BoxHeavy-dutyTrue RMS multimeterDouble-molded test leadsMagnetic hanging strap9 volt batteryCarrying caseUser manualNIST calibration is also available Manufacturer SpecsDisplay Counts4,000 countAveraging/True RMSTrue RMSBasic Accuracy0.5%DC/AC Voltage0.1mV to 1000VDC0.1mV to 1000VACDC/AC Current0.1μA to 10AResistance0.1Ωto 40MΩCapacitance0.01nF to 100μFFrequency (electrical)5Hz to 1kHzFrequency (electronic)0.001Hz to 10 MHzTemperature-4 to 1382°F(-20 to 750°C)Duty Cycle0.1 to 99.9%Diode/ContinuityYesDimensions7.25x3.25x2.25"(184x83x57mm)Weight12.3oz (349g)Tech SpecsMultimeters TemplateTypeDigitalStyleHand-HeldMeasures AC VYesMeasures DC VYesMeasures AC AYesMeasures DC AYesTrue RMSYesMaximum Voltage AC1000 VMinimum Voltage AC0.1 mVResolution AC Volts0.1 mVMaximum Voltage DC1000 VMinimum Voltage DC0.1 mVResolution DC Volts0.1 mVMaximum Current AC10 AMinimum Current AC0.1 uA (0.00010 mA)Resolution AC Current0.1 uA (0.00010 mA)Maximum Current DC10 AMinimum Current DC0.1 uA (0.00010 mA)Resolution DC Current0.1 uA (0.00010 mA)Basic Accuracy V DC0.5%Counts4000 .BacklightYesManual/AutorangingBothDual DisplayNoAnalog Bargraph on DisplayNoDecibelsNoResistanceYesFrequencyYesContinuityYesCapacitanceYesTemperatureYesDiode TestingYesCAT RatingIV CAT Voltage600 VIntrinsically SafeNoPeak HoldNoOverload ProtectorYesKelvin 4-Wire Measurement CapabilityNoWireless DisplayNoData HoldYesLow-Pass FilterNoDuty Cycle %0.1% to 99.9% Test Equipment General AttributesUnique FeaturesDiode Open Circuit Voltage of 2.8VDC, Auto Power Off with Disable Feature, Dual Frequency, Waterproof (IP67), Drop-proofWarranty3 YEARSMultimeter
