Clamp Meters

The Clamp meter was invented by Amprobe in 1948 and they have continued to innovate and evolve since. Amprobe offers many options whether the requirement is for industrial, commercial, or residential use.

The Amprobe ACD-10 Plus Clamp Meter measures AC and DC voltage up to 600V as well as 600AC current. The 10mm thick jaws make it easy to maneuver between tightly packed conductors. Measure capacitance, frequency, and resistance up to 40MΩ. The rubber-over molded case absorbs shock. The meter includes test leads and a soft carrying pouch.

Amprobe’s model ACD-23SW Swivel Clamp meter includes a patented 180-degree rotating head clamp design making easy views of measurement in inconvenient and tight places possible. Rotate the body of the clamp meter for an unobstructed view of the LCD display. Measure AC/DC voltage, AC current up to 400 AC Amperes, and temperature. The ACD-23SW also features Advanced VoltTect non-contact detection.

For HVAC and electrical multimeter versatility, the Amprobe ACD-14 Plus Dual Display Clamp Multimeter with Temperature allows measurements of microamps, capacitance, frequency, and temperature with the included thermocouple. Measure frequency, capacitance to 3000μF, and resistance to 40MΩ. The dual display feature permits simultaneous readings of amps and volts up to 600 Amps AC and AC/DC Voltage up to 600V.

Electrical motor maintenance and HVAC testing in high voltage industrial environments are what the Amprobe AMP-330 1000A AC/DC True RMS Motor maintenance Clamp Meter was designed for. The rugged capabilities of this meter allow AC/DC current measurements to 1000 Amperes and AC/DC voltage to 1000 volts.

The Fluke digital clamp meter is the most versatile tool for everyday use. They are designed for noise-free and reliable readings. Fluke clamp meters are simple to use and great for tight and compact spaces.
Fluke’s model 323 True RMS Clamp Meter is a rugged and reliable basic True RMS Clamp Meter with the ability to measure current to 400 Amperes AC and voltage up to 600 Volts AC or DC. It also measures resistance up to 4kΩ with continuity detection.

The Fluke 325 True RMS Clamp meter provides you with a versatile tool for measuring AC and DC Current, Voltage, Temperature, and Frequency. The instrument comes with a K-Type Thermocouple, soft case and TL75 Test Leads. A reliable tool for troubleshooting both commercial and residential jobs.

For HVAC technicians Fluke offers the model 902FC True-RMS HVAC Clamp Meter. With its wireless Fluke Connect enablement, this instrument is designed specifically for HVAC technicians. Measure resistance up to 60kΩ, capture flue gas temperature, measure start and run motor capacitors and variable frequency drive performance

Advanced troubleshooting for industrial and commercial electricians is the category that requires the highest possible safety protection. The Fluke 376FC carries a CAT III 1000 V, and CAT IV 600 V safety rating. It enables you to log, trend, and monitor measurements while remaining safely away from the arc flash zone through Bluetooth connectivity. Measure voltage to 1000 V AC or DC, 1000 µF capacitance measurement, Resistance to 60 kΩ, 500 mV DC measurement range to interface with other accessories, Includes an 18-inch iFlex Flexible current probe, TPAK magnetic hanging strap, TL75 Test leads, and soft carrying case.

Reduce downtime with the Fluke 368FC Leakage Current Clamp Meter. The ability to detect, document, record, and compare leakage current readings over time helps the user to prevent unplanned downtime and identify intermittent GFCI and RCD trips without taking equipment off-line. The Fluke 368FC features a large 40mm diameter jaw and is fully shielded to accurately capture very small leakage signals and minimize external electromagnetic interference.

Reliably handle a wide range of high-current applications with the Fluke 355 True FMS 2000 A Clamp Meter. Accurate peak measurements can be taken using the in-rush current mode, ideal for motors and inductive loads. A large backlit display allows easy visibility in low lit areas. Use the low pass filter to smooth out noisy loads and stabilize readings.

Extech Instruments has provided Test and Measurement tools for the professional, tradesperson, and DIY’er since 1971. Their diverse Clamp Meter line is loaded with the innovative quality handheld test, measurement, and inspection tools.

The Extech MA200: 400 A AC Compact Clamp Meter features a 2,000 count LCD display. Features include Continuity Beeper, Diode Test, Data Hold, Max Hold, Overload protection for all ranges, test leads, carrying case, and batteries.

Compact in size, the Extech model MA410 AC Current Clamp Meter also includes Non-Contact Voltage Detection. Measure capacitance, resistance, frequency as well as temperature to 1400°F with the supplied Type K bead wire probe.

The EX655 is a 600 Ampere, AC/DC True RMS Clamp Meter. Functions also include AC/DC Voltage, resistance, capacitance, frequency, temperature, continuity/diode test and features Non-Contact Voltage Detection. Equipped with a Low Pass Filter for accurate variable frequency drive signals.

Non-Contact temperature measurement is a feature of the EX840: 1000A AC/True RMS/DMM+IR Thermometer. Measure AC and DC current to 1000 Amps and Voltages to 1000 Volts AC and DC. The 1.7-inch jaw on this rugged meter fits around conductors up to 750MCM.

STB is an American manufacturer of Analog Clamp-On Ammeters intended to read electrical current in a circuit. The hands-free design provides fast and accurate readings while allowing the user to clamp on to any size conductor with various jaw-opening options. Jaw sizes are available from 2.5 inches to 6.0 inches. The ammeter can easily attach to a hot stick with the clamp-on adapter installed at the factory.
